The tablet is not charging from the network. The tablet is not charging. What to do? Sometimes, the tablet only charges when turned off. This happens for a number of reasons
Many users of Android devices sooner or later face the problem of charging their gadget. It either stops charging at all, or is discharged in a matter of hours. In addition, there are many other problems related to the operation of the charger, battery, etc. So, let's take a closer look at the most common of them and try to find a solution!
Your Android phone or tablet has stopped charging. What to do?
First of all, let's look at the known problems associated with direct charging of devices based on the Android operating system. There are several such problems, and each of them has a number of features. Therefore, before proceeding with the solution, make sure that the reason is appropriate.
Check charging
First, you need to check the charger itself. To do this, do the following:
If the charge has increased, everything is in order with the charging itself. If not, look for the specific issue below.
Device shows charging but not charging
This problem is one of the most common. You plug in the charger and see that the phone is charging. Without a shadow of a doubt, you leave it on charge and leave or continue to use it. However, as soon as you take out the charge, the gadget immediately turns off, or it turns out that the percentage of the charge has not moved, or even dropped altogether. There may be several reasons for this behavior of a smartphone (or tablet):
When using chargers of brands other than the brand of the gadget itself, there is a possibility that both the charger and the phone will not work properly. This is due to incompatibility, for example, voltage or other parameters. It is clear that in this case you just need to change the charge to "native". You can buy it if the standard one is broken at any hardware store.
If the charger itself breaks down, the only way out, of course, is to buy a new one. However, it is difficult to “diagnose” such a breakdown. This can be done with a multimeter by checking the stability of the voltage on the charger. It is unlikely that a typical user at home has such a device, so it is better to contact the workshop. But before doing this, check the battery.
"Humpbacks" on a swollen battery
Battery failure is much easier to determine. Turn off your phone or tablet and open the back cover of the device. Carefully remove the battery. Check it for the presence of characteristic "humps". If there are any, then it is swollen and needs to be replaced. Again, you can buy a new battery at any mobile hardware store. Its price is quite acceptable.
Charger cable defects are also quite easy to identify. Unplug the charger from the socket and, closing your fingers on the wire, run them from edge to edge. You will immediately notice if the cable is torn or incorrectly bent.
If you didn't find any of the above, the charging socket on your phone is most likely broken. Usually it is also used to connect the USB cable. Therefore, you can quickly identify the presence of a socket problem by connecting your device to a computer. Repairing the nest at home is not recommended. Contact the master, who will check everything and, if necessary, change. By the way, this service also does not require large expenses.
Device not charging with USB cable
Check the USB cable
If your Android device is charging from the charger, but not from the USB cable, then the problem is most likely in the cable itself. Run the diagnostics below. Most likely you will find the problem.
If none of the above helped you, the problem may be software in nature. Then take the device in for repair.
Smartphone or tablet not charging after being completely discharged
This problem, in most cases, is not a problem at all. This behavior of the gadget may be due to the lack of any backup energy. For example, the car cannot be started if the battery is completely discharged. Approximately the same thing happens with the phone (tablet). To solve the problem, leave it to charge for several hours, and do not try to turn it on. Soon your favorite gadget will "come back to life".
Restoring the battery after a complete discharge
If the device still does not charge, most likely the problem is in the charging unit or battery. We described above how to diagnose them. Well, if this does not help, contact the service center, because the failure of the operating system can also occur.
The tablet is completely discharged and no longer charges or turns on
Such a problem is most likely the quintessence of the other two. Namely:
Carry out the described diagnostics. If it did not help, the error lies in the operating system itself. Then you need the help of a specialist.
The device stopped charging from the cigarette lighter
Charging from the cigarette lighter is defective
If your gadget "refuses" to charge from the cigarette lighter in the car (but in all other cases it charges), it is obvious that the problem is in the cigarette lighter itself or, more likely, in the car charger. In this case, the only solution may be to replace this block.
Device flickers but won't charge
The most common reason for this phone or tablet behavior is CPU overheating. The device, in order to avoid this, is periodically disconnected from charging by software. The presence of such a problem indicates a hardware malfunction of the smartphone itself. Therefore, only professional diagnostics can help.
What if the device is charging, but something goes wrong?
By "something goes wrong" is meant a number of possible "anomalies" in the operation of the gadget. Despite the strangeness of some of the errors, most likely, finding a solution to them is quite simple. The most common faults are described below.
Charging only when switched off
Such an unusual, at first glance, error often has a very prosaic character. If there are no problems with the charging unit and the battery (see the diagnostics of these parts above), then the whole thing is in the installed software. The fact is that often individual programs “come into conflict” with others. The similarity of the codes being executed leads to the fact that the device simply does not know what to do: whose request to execute first.
Get rid of bad software
If your device is charging only when turned off, then the error is provoked by a program aimed at working with the battery. An example of such a program could be some kind of "battery charge manager" or something similar. Removing excess software will help to cope with the problem. In addition, do not forget to clear the cache using special programs (use only popular and proven ones, for example, Clean Master).
The device is charging, but not completely
Such a problem, most often, appears in budget tablets and phones from manufacturers, which are popularly called "Chinese". Most likely, when collecting this or that gadget, it was decided to save on costs. Anyway, there are several solutions to this problem.
If none of the above helped, contact the wizard to replace the battery or charger.
The device does not charge more than 1%
One or the other solution to this problem is unlikely to work for everyone. It can be associated with a battery or charging malfunction, or with malicious or low-quality software on the device. To determine what caused this behavior of your gadget, carry out a complete diagnosis of it according to all the above recommendations. If all else fails, contact the service center.
Charging is not performed until the device is rebooted
Charging won't happen until reboot
The appearance of this problem indicates, in most cases, a software malfunction. The cause of such a malfunction may be special programs for working with the battery, which were described earlier. "Clean" your phone or tablet from additional software, and the problem will go away.
Device runs out of power even when turned off
In this case, there is hardly any problem. After all, any phone or tablet spends a small amount of energy even when turned off. For example, you need to keep the clock running on the device or turn on the alarm in time (on some phones it works even when they are turned off), etc.
However, if the discharging of the turned off device occurs too quickly, the battery is most likely broken (swollen or leaking). Check it yourself and, if a breakdown is found, buy a new one.
The device is charging, but shows an incorrect charge value
The presence of this problem can be the first signal for a breakdown of any kind (from those described above). Check all hardware and software of the device. You will surely find the problem without the help of a wizard. Most often, in this case, replacing the battery will help.
The gadget on Android runs out of battery quickly: what is the reason and what is the solution?
Solving the problem of fast discharge
Fast discharging of the device is a very common problem of our time. Any phone or tablet from any manufacturer almost always does not withstand even three or four days of work. And sometimes the time from charge to charge is reduced to several hours. What to do? How to prolong battery life? Let's try to figure it out!
What processes contribute to rapid discharge?
The rapid discharge of an Android device in many cases is associated with reasons such as:
All these problems can be solved without the use of special tools or skills. All it takes is a little care.
Frequent network searching is due to the instability of your mobile operator coverage. So, if you are traveling by train, the connection will often be lost, which is why the phone will try to find it again and again. This takes a lot of energy. To avoid running out of juice on the go, turn on Airplane mode. If the search for a network occurs on ordinary days, it may be worth considering changing the operator.
Remember to turn off Wi-Fi when you move away from the hotspot. For example, if you leave it on on your way to work, your phone or tablet will constantly monitor nearby routers. The same applies to GPS, only in this case the connection to satellites is maintained, which also requires energy.
Remove unnecessary programs. If there are none, try choosing the ones you rarely use. Today, almost all Android applications run in the background with some resources, which means that the device needs a lot of energy to support their work.
The device quickly charges and / or quickly discharges
Most of the time this is a battery issue. Most likely, it smudged and the capacity physically fell. Check the battery for bulges as well. Also, uninstall third-party battery management software, if any.
Phone or tablet takes a long time to charge and quickly discharges
What to do if the phone takes a long time to charge?
In this case, we can say with absolute certainty that the device does not have enough battery capacity. Whether the battery itself has broken, or the problem is in a large number of installed programs, it is difficult to immediately say. Check the battery first to avoid further damage. If everything is in order with it, get rid of unnecessary programs and follow the recommendations about networks mentioned above.
Android device runs out of power quickly in standby mode
This problem is almost identical to the previous two. It doesn't matter if your phone or tablet is in standby mode or you are actively using it. There are always background processes, and battery life depends on their proper organization.
Battery drops sharply
Battery charge drops sharply
If you notice that in some cases the battery power drops suddenly quickly, you should try to determine in which ones. Most likely, some program is running its own code, which requires too many resources. The processor receives a lot of tasks and simply overheats. If it was not possible to determine the "pest", it makes sense to completely reinstall the operating system.
The device began to discharge quickly after the update
This problem is usually faced by owners of older versions of devices. For example, phone Samsung Galaxy Ace II originally released based on the operating system Android 2.3.6. However, after a while, the manufacturers decided to "please" the owners Ace II new system Android 4th version. As it soon turned out, the phone is simply not able to cope with it. In addition to frequent glitches, it began to overheat and, accordingly, quickly discharged.
Odin program
How to be in such a situation? The best solution is to make a backup. That is, you need to reinstall the operating system, returning the previous version. You can do this with the program Odin.
A new device from the store runs out of battery quickly
If you are experiencing this problem, check out the reviews of the same device from other consumers. And if the majority does not complain about the fast discharge, you need to contact the seller with a request to change the product. It is possible that the distributor will redirect you to the manufacturer. In any case, this problem is easily solved.
How to check the battery status of a device?
To find out exactly what percentage of battery charge is on your phone or tablet at the moment, go to "Settings". Find the section there. "Device Information" or something similar. In it you will see the numbers you are interested in. It is useful to do this periodically if you want to know exactly how much continuous work time you have left. Besides, in "Information..." you can find information about which applications consume the most energy, which is also very practical, given what we said above.
In rare cases, a question mark ("?") may be seen on the battery icon. Its appearance indicates that something is wrong with the battery. The problem could be both hardware and software. Therefore, it is necessary to conduct a complete battery diagnosis in order to identify possible defects and / or errors.
How to check the battery for swelling was discussed above. As for smudges, the word speaks for itself. If they are found, the battery must be changed immediately. In addition, contact the master to check if the electrolyte liquid has damaged the device itself.
How to charge an Android device if the socket is broken?
Using wireless charging
If you need to quickly charge your device before fixing a broken socket, you can purchase a wireless charger. It is a kind of card that is placed on the battery inserted into the phone. However, not all phones and tablets support this feature. In addition, the cost of wireless charging is usually higher than the cost of repairing the socket at a service center. So it's better to wait.
How to properly charge Android devices?
How to properly charge Android devices?
Finally, it should be said that many battery problems are associated with improper or incorrect charging. To avoid these problems from recurring, follow these simple guidelines:
Users of the Android OS, in most cases, speak positively about it. And if negative feedback appears, most often they are associated with problems with battery charging, battery life, etc. However, this article is direct proof that these shortcomings can be easily dealt with. The main thing is to know where to look!
You may have noticed that the demand for tablets is huge. You can judge this by the number of devices that we meet every day: people with tablets can be seen on the street, in public transport, in cafes ... I won’t lie, this didn’t pass me by - I am the owner of an inexpensive tablet of one little-known in our edges of the firm. I can say that I obviously went too far with the size, because holding an almost 10-inch device in my hands is simply inconvenient. However, I will talk about this some other time.
Today I would like to talk about one very common problem faced by a large number of users using such devices. Yes, I want to talk about why the tablet is not charging, because I myself encountered this problem.
Causes of the problem
I'll start with this. Most often, the problem is encountered by those users who missed the moment when the charge of the device is worn out and did not put it on charge in time. I can say that it is not recommended to bring it to such a state, since it is the complete discharge of the battery that adversely affects its service life. In addition, often after discharging the tablet refuses to charge.
- The first and most common reason is a problem with the charger. Manufacturers are trying to save on everything and the charger is no exception. Poor-quality "chargers" are found all the time. How do you know if it's the charger? You need to connect the tablet to a known working "charger". Here, however, everything can be individual. One of my "chargers" stopped charging the tablet one day. I thought that it had broken down and connected it to a known working one - he charged it. Okay, I thought, but I decided to check the original charger the next day - it functioned exactly the same as before. A few days later the situation repeated itself. Apparently, there is some problem in the "charger", which, by the way, is still working. But I didn’t find out exactly what the problem was, and I didn’t really try, because I bought an additional charger just in case. Probably, the matter is in the stabilizers or the failure of the power circuit.
- Problems in the electrical network, such as power surges, cannot be discounted. In this case, it is recommended to check the presence of voltage in the network. But I recommend doing this strictly to those users who at least work as electricians, otherwise such measurements can end very badly for you. Be careful!
- In cases where there is voltage, and the tablet still refuses to charge, you can try to clean the contacts of both the charger and the tablet connector. Do this carefully so as not to damage the device.
- If we talk about more mundane problems, it very often turns out that when the tablet is initially connected to the charger, it refuses to charge, but once it is left plugged in for at least a few hours, it magically starts charging. Therefore, first of all, hold the device longer on the charge.
- Another category of users connects the gadget to the computer and complains that there is no charge. Should he be? The fact is that not all devices are able to charge from a computer, because for this they simply do not have enough power.
- If the tablet still has the ability to charge from the USB port, then there is a high probability that the port itself is faulty or it is disabled.
- Don't forget about the cable itself. If you have cats, dogs or other animals at home, it is likely that they have had time to play with your charging cable, which has become unusable due to this. In this case, only its replacement will help.
- You may be surprised, but the problem may also be related to unstable firmware. Fortunately, this rarely happens, but I have heard of such cases more than once or even not twice. Flashing to a stable firmware can help, moreover, through the recovery mode (unless, of course, it is possible to boot into it).
- Theoretically, of course, a problem with the hardware or the battery is possible, but in most cases the problem is related to the software. Therefore, before carrying it to a service center, you need to try to reanimate it yourself, especially since it is often easy to do this.
If your tablet is not charging, you can ask your questions through the comments. Just be sure to include the make and model of your device, such as Samsung Galaxy Tab 2 or iPad Air.
With all the functionality and reliability, modern gadgets are not without flaws - they periodically fail and need to be repaired. If the tablet does not charge, turns off after being turned on, freezes or works slowly, it should be shown to the master. The causes of malfunctions can be very different - it is often impossible to determine them without having the necessary diagnostic equipment at hand. To answer the question why the tablet quickly discharges or does not charge, only a professional with many years of experience in servicing devices can do it. Nevertheless, it is desirable for each user of a tablet computer to have a basic knowledge of the principles of its operation in order not to sound the alarm in the event of a breakdown and to avoid malfunctions.
If your tablet stops charging - how to find out the reason?
Many users of modern gadgets are dissatisfied with the fact that their "assistants" are discharged in a few hours, it is absolutely impossible to work with them away from the outlet. However, rapid battery drain is a problem with most devices and can be dealt with by setting the appropriate settings or by using a portable battery. It is much worse if the new tablet does not charge when connected to the network - in this case, the device requires comprehensive diagnostics and competent
Failure of the following elements of the tablet computer can lead to a problem:
- cable (the wire can be damaged both during operation and during storage - being wound up);
- charger adapter (breaks due to overheating or power surge);
- battery (it may lose capacity as a result of natural wear and tear or under the influence of external factors);
- connectors (loosen and deformed);
- power controller.
If the wire is the culprit, it must be replaced. It is convenient and advantageous to use a USB cable. If the tablet has stopped turning on and charging due to the fact that the limit of charge cycles has been exhausted, it is worth purchasing a new battery, it is advisable to repair the existing one in rare cases.
How to solve the problem with a long tablet charge
For those who prefer to use touch devices, buying a tablet computer is an absolute must. With it, you can access the Internet, create graphic and text files, process large amounts of information. The only drawback of modern tablets is that after a certain period of time they charge slowly and discharge quickly. However, this problem can and should be fought - the main thing is to determine what factors led to its occurrence. If your tablet battery takes a long time to charge, you may be experiencing the following problems:
- the battery is worn out;
- connectors for connecting the USB cable are deformed;
- the voltage in the network has decreased significantly;
- faulty charger;
- there was a factory defect.
In some cases, it can be concluded that the device failed due to the fault of the user himself. The battery charge is often disrupted due to careless handling of the gadget - it is dirty, wet, or infected with viruses. If it takes too long to charge your tablet, you should take the following measures - change the outlet, replace the worn cable, install a new battery. If you couldn’t solve the problem yourself, and the tablet is still charging slowly, you should contact the wizard. He will diagnose the device and establish why it is not possible to charge the battery in the allotted time.
How long should the tablet charge
Charging speed and battery life are important criteria for choosing a gadget. The duration of the functioning of the device without recharging is determined by the volume of the built-in battery, and how quickly the tablet charges also depends on it. Devices of well-known brands can work autonomously for about 10 hours, there are also devices on the market that do not reach this indicator. Before you buy a tablet PC, you should ask about its technical characteristics and read user reviews. In most cases, the tablet charges in 2-6 hours - the newer the battery, the faster this process. The battery life is significantly less than the life of the device, so it will have to be changed every 2-4 years.
The tablet does not charge when it is turned on, how to fix the problem?
If the switched off device cannot be charged, first of all it must be turned on and connected to the charger in this state. If the tablet is charged only when it is turned off, do not panic - this is not a breakdown, but a feature of the device. In most cases, the situation can be corrected. The main thing is to understand what caused it. The tablet computer is charged only when turned off if: an unofficial operating system is installed, the power supply is faulty, the contacts are clogged, the cable is damaged. To be able to charge the device while it is on, it is worth flashing it, testing the charging and USB cable, and wiping the contacts from dust with alcohol. Experts recommend charging the gadget exclusively with a “native” device, otherwise the battery capacity may be significantly reduced. Original accessories can be purchased at the company store or service center.
Where to repair the charger for the tablet
Only true professionals can quickly and efficiently - independent intervention in the operation of the device often leads to new breakdowns. Repair charging the tablet and replacing its battery can be entrusted to the specialists of the service center. They will diagnose the gadget and answer in detail the question of what exactly caused the problem. Only original spare parts must be available to the workshop staff. It is desirable that the quality of the work of specialists be documented. Reliable SCs offer a long-term guarantee for all types of services.
Is your favorite tablet not charging? What to do? In fact, this is a fairly common problem with mobile devices, especially tablets. But everything, as always, is solvable - we will help you find the causes and understand how to fix these problems. Some problems you can handle on your own, and some will need to be addressed by specialists.
We want to immediately draw your attention to the fact that you need to contact the service center only before the expiration of the warranty period (information is in the documents for your tablet).
In any other cases, it is better not to go there, because the repair is terribly delayed, they are not responsible for the quality, and the sellers (receivers) are trained to advise you to buy something unnecessary. If the warranty period has not yet passed, then there is no other way out than to contact the service center. They must establish whether the problem has occurred due to external influences and if there is no mechanical damage on the tablet, then you will be required to repair it for free. In the case when the warranty period has already expired, experience shows that it is "more expensive" to contact a service center. I am saying this from personal experience. What they wanted to take 1,500 rubles from me for (but, by the way, they could not do) in an ordinary workshop (express repair street pavilion) was done quickly and for only 500 rubles.
Let's get back to the topic of mechanical damage... With tablets, these same mechanical damages happen just very often, since people buy them to constantly have them with them, and having them with them, they can drop them, leave them in places where they fall, pour them on, and so on. Therefore, be careful, try to store the tablet in the cover, and carefully insert the charger into the socket, as it can be loosened. But let's not get ahead of ourselves. We list the reasons why the tablet may not accept a charge.
THE MAIN CAUSES OF NO CHARGING AND WAYS TO ELIMINATE THEM:
Let's start with chargers. CHARGING DEVICE Tablets are different. Some are solid, while others are arranged according to the cable + adapter principle. Here are photos of both options. Both for one-piece chargers and for a cable + adapter, breakdowns can be the same, the only difference is that you cannot replace the cable separately for a one-piece charger, you need to change the entire device. In a cable + adapter system, either one or the other can be replaced. So, from the more common problems to the less…
CABLE out of order. This is perhaps one of the most common reasons for the lack of charging. Some people often have to twist the cable to put it in a bag or put it on the table. Due to frequent twisting and kinking, the wire inside the cable breaks, the contacts are lost and the cable thus becomes unusable.
The second problem is ADAPTER. She happened to me. Assuming that the charge does not go due to poor contact with the socket, I stirred this socket. In the end, the tablet nest stirred and also deteriorated. And it was necessary to replace the adapter, because, despite all its charms - it was working, native, everything is fine, but - the adapter plug had little contact with the wires in our Russian sockets, tees and extension cords. The charge, thus, was constantly lost - the tablet was either charging or not. When the charging is turned off and on, the screen lights up, which in turn absorbs the charge. It often happened that due to frequent such shutdowns, instead of charging, there was a discharge. It took a long time to notice this... Therefore, check how well the plug of your charger contacts the outlet.
It was a problem with a working adapter that can "dangle" in the outlet. The adapter itself can also fail due to a sudden power surge, overheating, or poor quality. Both of the problems described are solved in one way - by purchasing a new adapter. It's good that they now have a large assortment in stores. When buying an adapter, be sure to pay attention to the current strength in it. To find out which adapter you need, look at the old adapter of your tablet, it should say 1.5A or 2A in small numbers. Buy an adapter with a amperage not lower than yours. A little higher is possible, lower is not desirable - it will not work for long and it will be bad to charge (if at all).
BATTERY
Among other reasons, there may be a failure of the battery. If the tablet, and accordingly the battery, is new, then the reason for the failure of the battery is most likely a manufacturing defect.
Over time, the battery can also fail due to loss of capacity due to the natural exhaustion of the limit of charge cycles. If the warranty period for servicing your tablet has already ended, and there are problems with the battery, you will have to buy a new one, although this is very undesirable, since after repair its reliability decreases.
PORT(connector/charging socket)
The charger connector can also cause a lack of power supply to the tablet. Problems can be different, mainly this happens due to mechanical damage. You may not remember when you hooked your mobile computer in such a way that the socket was damaged.
If you have already determined that your charger is in perfect order and other phones and tablets can receive power from it; that the contact with the outlet is normal, but the charge still does not work, then you should pay attention to the state of the port. To do this, it may be enough just to move the charger in the socket and see if the charge icon appears on the screen. But perhaps this will not be enough if the matter is not in contact with the charger, but in a broken socket. In this case, it will need to be replaced, and this will require the help of specialists. As mentioned above, it is not at all necessary to contact a service center for help (it is not even desirable if you want to quickly, efficiently and inexpensively). Replacing the port in private computer repair shops costs about 500 rubles (together with the cost of the nest itself).
POWER CONTROLLER
There is also a microcircuit in the tablet that is responsible for the distribution and supply of power in it. The reason for the failure of this spare part is also mechanical damage. If the controller is burned out, the battery of the device will not be charged. It is clear that only specialists can fix such a problem. For a good master, this is not a difficult job.
FIRMWARE
Firmware is a reinstallation of the operating system of the tablet. Sometimes the firmware is unsuccessful, but since only the owner of the device can be the initiator of the firmware, no warranty repairs apply to the flashed tablets, and if you need to reflash, you will have to do it at your own expense. As a result of a firmware error, the device may not charge, since the installed operating system is responsible for all processes in the tablet.
A firmware error can occur when the tablet turns off on its own due to battery discharge, with an incorrect system shutdown. Try restarting your device. If you are sure that there is no charge for this reason, then you can try to reset the settings to factory settings. If this still does not help, then there is another option - to reflash the tablet. Also on the Internet you can see articles on the topic “firmware error”, there are tips on what else can be done in this situation.
All of the above cases can cause both a complete absence and a very slow battery charging. Or both together. In general, this often happens. At first, the tablet charges more and more slowly, it comes to the point that it does not charge to the end for several days. Then, after some time, the charge stops flowing at all and the tablet does not turn on at all ...
Some causes of problems can be identified on your own, for example, check whether your charger (adapter and cable) is working, whether there is good contact with the network, whether there are large voltage transfers in the network ... Other problems, as you already understood, can only be identified with the help of specialists.
One more little nuance… when you come to the store for a new charger, before buying it (or a cable / adapter), you need to check the operation of the device on your tablet. If none of the commercially available charges your tablet, then there is no point in buying a new charger - the problem is inside the tablet and you should first seek help from specialists.

If suddenly your smartphone, tablet or phone stops charging or turns on, do not immediately get upset and run to a service center. We'll tell you what you can do to try to solve the problem. We do not guarantee that the following tips will help you. But it's worth trying.
Try restarting your device. If it freezes, press the power button for 5-10 seconds. If it does not help, try the combination of "On / Off" and "Volume Up" or "On / Off" and "Volume Down" (you need to simultaneously hold down two buttons for a few seconds).
If the device is discharged to zero, the first signs of life from the gadget will have to wait a few minutes(or tens of minutes if you are using a low current charger). You can even leave your smartphone on charge for several hours.
Maybe, charger is defective. Try a different, known-good network storage device. Or try to charge your phone from a computer. Please note that if the current from the charger is too low, some smartphones and tablets will not charge at all. Even if the memory is correct.
Try charge off. If a smartphone/tablet draws more current than it receives when charging, it will drain faster than it can charge. In this case, leave the gadget alone, or turn it off. Devices charge faster when turned off. Do not forget about this if you need to charge your phone as much as possible in a short time.
Maybe, cable is defective. This rarely happens. But still test charging with another cable.
Sometimes there are connector problems. Dirt can get into the microUSB connector on the phone, internal contacts can bend. Try to blow out the connector, gently clean it with a scraper. The connector can simply break or loosen in the socket.
Besides, microUSB connectors on cables come in different shapes. I was somehow helped by replacing one cable with another with a slightly different connector configuration.
Sometimes it helps to activate charging simple plugging in / plugging in the cable from the charger, as well as plugging in / plugging in the charger to different outlets. This does not solve the problem, but if you need to recharge urgently, you can try.
Finally, you can try a hard reboot. Please note that in this case all your data from the smartphone will be deleted (!) Press the "Volume Up" button, and then the power button. After the boot menu appears, use the volume buttons to go to Setting, then Format System and Reset Android. The selection is made with the power button. The tablet will reboot and the bare Android system will be restored. And not the fact that it will help.
Tips for using modern gadgets
Previously, we were taught that it is desirable to discharge phones to zero, and after buying a new device, perform two or three “full discharge-full charge” cycles. These tips were relevant for nickel-metal hydride and nickel-cadmium batteries. Modern lithium-polymer batteries do not need these procedures. They cause more harm than pain. Modern smartphones and tablets do not recommend discharging before turning off- put devices on charge if the charge level drops below 50%.
I will also answer another popular question: which charger is best to charge gadgets. The best option: use the memory that came with the kit.
At the same time, you can charge phones and tablets with any other chargers. If the current strength is less than necessary, the gadget will charge more slowly than usual. If the current strength is greater, the charging controller built into the smartphone will limit the current strength to the required level.
Any modern electronics can also be charged from USB connectors on PCs, monitors, etc. In this case, you will get a current of 500 mA (USB 2.0).
Tablets and smartphones familiar to us work due to the batteries built into them. Unfortunately, classic lithium-ion batteries are far from the safest and most durable. Like any battery, a tablet battery can fail. In this case, you will not be able to charge it. This fact is not very pleasant and requires user intervention. However, there may be other reasons why the battery behaves inappropriately. There are many reasons and all of them are completely solvable. In this article, we will try to figure out why your tablet is not charging and what to do in such a situation. And at the end you will find a small guide on the proper "care" of the battery.
What to do if the tablet does not charge and does not turn on
If you look for statistics, then the most popular call to services after broken displays will be a failed battery. Problems with the power controller and cables can also be included in this category. All of them in one way or another affect the charging speed and its operation in general. It often happens that the tablet does not charge at all. Faced with such a nuisance, you need to consider all possible causes and, based on them, make further decisions.
Charger check
Charger problems - The very first and most common reason why the tablet does not charge is a faulty charger. In most cases, one or more capacitors in the power supply case fail. You can test this theory with another charger or with a multimeter. To solve the problem, you can replace the power supply or repair it if you have the appropriate skills. Fans of wielding a soldering iron or those who attended a radio circle as a child will certainly cope with this task.
Cable failure
A damaged cable is the second most common reason for not charging. A visual inspection is almost always enough to be sure of this. Tears, bends, exposed insulation: these factors can indicate "lethal" damage. Try to do without sudden movements, do not pull the cord, do not bend it or throw it anywhere. Often, users save money and purchase unofficial cables, which can also be a problem when charging a device. It is not worth solving the problem with repairs, it is better to replace the cable, especially since they are not so expensive.
Bad contact in connectors
Connector problems are another hardware problem that often torments owners of modern devices and due to which the tablet does not charge. There are two options. Either water or dirt got into the connector, and then to restore functionality, you just need to clean it thoroughly. Or one of the contacts burned out and you need to contact the service center, where the charging port will be replaced with a new one.
Software failure
A software error - naturally, the “brains” of a mobile device can also fail and prevent the gadget from charging. Sometimes the tablet shows charging, but does not charge. Sometimes it charges too slowly. There are many problems, but all of them are solved by reinstalling the firmware. This is the first thing to do if you own an Android device.
Apple gadgets may also stop charging because you are using a cable that is not Apple certified. In this situation, before charging, the device must be completely turned off.
Battery failure
A defective battery is a problem that overtakes everyone who has been using a tablet for a long time. The battery installed in your tablet is not eternal. Its capacity gradually decreases and soon the battery fails. This is one of the most common problems on the iPad. If it does not turn on or does not charge, it is possible that the battery has died. Even more often, the battery fails when the gadget is physically damaged or used in abnormal temperature conditions. The solution is always the same - replacing the battery in a service center. They do it very quickly and very inexpensively.
Failure of the tablet itself
Malfunctions of the device itself are another vice that haunts all lovers of cheap power supplies and cables. If the tablet takes a long time to charge and its back panel overheats, then be sure the power controller is out of order. Another harbinger of this trouble is turning off the tablet when it reaches 20-30% of the charge. To restore the normal operation of the device, a very complex repair is required, so think twice which is better, change the device or give it to a service.
How to properly charge your tablet and prolong battery life
The problems described above can occur both as a result of normal use of the tablet, and in case of careless handling of the gadget. The lithium-ion battery is dependent on the constant circulation of energy in it. Any deviation from normal use may damage the battery. At first glance, this sounds complicated, but in reality, you just need to develop a few good habits and follow them when using mobile devices. The life of the battery, and with it the life of the gadget, can be extended if you follow a number of tips and tricks.
- Do not let the gadget go into a deep discharge. The tablet's battery should always be receiving power. The device must be fully charged and discharged at least once a month, otherwise the battery will quickly use up its resource and simply “die”. If you don't use your gadget regularly enough, don't forget to let it charge occasionally so that it continues to function normally.
- Don't overcharge. You do not need to constantly power the device from the mains. The tablet is not a computer, therefore it cannot take energy directly from the network, but constantly recharges the battery, which significantly harms it. Experts recommend keeping the charge level between 20% and 80%. This is ideal for a lithium-ion battery.
- Do not use the Tablet PC while it is plugged in. This, of course, is very difficult, but it is better not to do this. Let the gadget calmly charge, and only then start working with it.
If the charge has not reached the maximum mark, and you urgently need to get to work or write to someone, then it is better to disconnect it from the network. This is also important if the tablet is 100% charged, before starting work with the gadget, remove the cable from it.
Conclusion
Here we come to the end. Now you know why the tablet stopped charging, what to do in this difficult situation and how to use the device correctly in order to avoid similar problems in the future. The main thing is not to neglect the advice of our experts, and then the device will serve you much longer.
With all the functionality and reliability, modern gadgets are not without flaws - they periodically fail and need to be repaired. If the tablet does not charge, turns off after being turned on, freezes or works slowly, it should be shown to the master. The causes of malfunctions can be very different - it is often impossible to determine them without having the necessary diagnostic equipment at hand. To answer the question why the tablet quickly discharges or does not charge, only a professional with many years of experience in servicing devices can do it. Nevertheless, it is desirable for each user of a tablet computer to have a basic knowledge of the principles of its operation in order not to sound the alarm in the event of a breakdown and to avoid malfunctions.
If your tablet stops charging - how to find out the reason?
Many users of modern gadgets are dissatisfied with the fact that their "assistants" are discharged in a few hours, it is absolutely impossible to work with them away from the outlet. However, rapid battery drain is a problem with most devices and can be dealt with by setting the appropriate settings or by using a portable battery. It is much worse if it does not charge when connected to the network - in this case, the device requires complex diagnostics and competent
Failure of the following elements of the tablet computer can lead to a problem:
- cable (the wire can be damaged both during operation and during storage - being wound up);
- charger adapter (breaks due to overheating or power surge);
- battery (it may lose capacity as a result of natural wear and tear or under the influence of external factors);
- connectors (loosen and deformed);
- power controller.
If the wire is the culprit, it must be replaced. It is convenient and advantageous to use a USB cable. If the tablet has stopped turning on and charging due to the fact that the limit of charge cycles has been exhausted, it is worth purchasing a new battery, it is advisable to repair the existing one in rare cases.
How to solve the problem with a long tablet charge
For those who prefer to use touch devices, buying a tablet computer is an absolute must. With it, you can access the Internet, create graphic and text files, process large amounts of information. The only drawback of modern tablets is that after a certain period of time they charge slowly and discharge quickly. However, this problem can and should be fought - the main thing is to determine what factors led to its occurrence. If your tablet battery takes a long time to charge, you may be experiencing the following problems:
- the battery is worn out;
- connectors for connecting the USB cable are deformed;
- the voltage in the network has decreased significantly;
- faulty charger;
- there was a factory defect.
In some cases, it can be concluded that the device failed due to the fault of the user himself. The battery charge is often disrupted due to careless handling of the gadget - it is dirty, wet, or infected with viruses. If it takes too long to charge your tablet, you should take the following measures - change the outlet, replace the worn cable, install a new battery. If you couldn’t solve the problem yourself, and the tablet is still charging slowly, you should contact the wizard. He will diagnose the device and establish why it is not possible to charge the battery in the allotted time.
How long should the tablet charge
Charging speed and battery life are important criteria for choosing a gadget. The duration of the functioning of the device without recharging is determined by the volume of the built-in battery, and how quickly the tablet charges also depends on it. Devices of well-known brands can work autonomously for about 10 hours, there are also devices on the market that do not reach this indicator. Before you buy a tablet PC, you should ask about its technical characteristics and read user reviews. In most cases, the tablet charges in 2-6 hours - the newer the battery, the faster this process. The battery life is significantly less than the life of the device, so it will have to be changed every 2-4 years.
The tablet does not charge when it is turned on, how to fix the problem?
If the switched off device cannot be charged, first of all it must be turned on and connected to the charger in this state. If the tablet is charged only when it is turned off, do not panic - this is not a breakdown, but a feature of the device. In most cases, the situation can be corrected. The main thing is to understand what caused it. The tablet computer is charged only when turned off if: an unofficial operating system is installed, the power supply is faulty, the contacts are clogged, the cable is damaged. To be able to charge the device while it is on, it is worth flashing it, testing the charging and USB cable, and wiping the contacts from dust with alcohol. Experts recommend charging the gadget exclusively with a “native” device, otherwise the battery capacity may be significantly reduced. Original accessories can be purchased at the company store or service center.
Where to repair the charger for the tablet
Only true professionals can quickly and efficiently - independent intervention in the operation of the device often leads to new breakdowns. Repair charging the tablet and replacing its battery can be entrusted to the specialists of the service center. They will diagnose the gadget and answer in detail the question of what exactly caused the problem. Only original spare parts must be available to the workshop staff. It is desirable that the quality of the work of specialists be documented. Reliable SCs offer a long-term guarantee for all types of services.
The battery capacity of most Android smartphones and tablets allows you to actively use the device without recharging for 12-24 hours. The charging time of the device is two to three hours. But sometimes the gadget abruptly drops the charge level, quickly discharges, loses the battery charge level when connected to a power outlet, or completely stops responding to the charger being connected. If your smartphone has stopped charging, explore the possible causes and solutions for this situation.
What to do if your Android phone or tablet is not charging. Possible reasons
Common reasons for the lack of charging are a breakdown of the power supply or microUSB connector, battery wear, and software failures. Realizing that the smartphone or tablet is not charging, first of all check the voltage on the contacts of the battery and charger. If everything is in order, use other methods to restore your smartphone or tablet.
Indicates that charging is in progress, but not charging from the network
If, when connected to a power outlet, the indicator shows the charging process, and when you disconnect the cable, the smartphone or tablet turns off, the charge level controllers have probably shorted. A short circuit occurs as a result of water entering the case or a broken connector.
Try testing the device with a different cable and battery - if the result is the same, take your smartphone or tablet to a service center. Specialists will find and replace the defective element.
The percentage of charge does not change via USB from the computer
Users often charge smartphones and tablets from a laptop rather than from an outlet. Reasons why a smartphone with a good battery does not receive power from a computer:
- rupture or insufficient cable thickness;
- insufficient current for charging;
- the connection is blocked by the PC operating system;
- USB charging is disabled in the device menu.
Finding a broken wire, connect the two torn ends together and rewind with electrical tape. If the current supplied to the USB port is not sufficient for charging, try connecting the device to a different port.
More often than others, the Ubuntu operating system blocks charging. To bypass the blocking, blacklist your smartphone along the path /etc/default/tpl.
Fully discharged and not charging
Smartphones and tablets do not respond to the connection of the charger when the battery is deeply discharged. If the gadget has been discharged more than a day ago and does not show signs of life, plug it into an outlet and leave it off. After 10 minutes, check if the charge indicator is on. If yes, you can turn on the device.
If the indicator does not light up, clean the contacts of the Micro USB connector and plug on the charger cable. Take a thick needle and use the reverse end to remove small dust particles and spools. Insert the plug into the socket and leave the smartphone or tablet for another 10 minutes.
A common situation when users suspect problems with charging is display failure. At the same time, the gadget is charging, but you do not see it - the screen remains dark. To check whether charging is in progress or not, use the indicator light on the case. If there is no indicator, turn on the device. If the display breaks, you will hear the characteristic sound of the system starting up, and if the charging connector does not work, the gadget simply will not turn on.
Stopped charging from cigarette lighter
When charging your smartphone in the car, you may encounter the problem of not being charged from the cigarette lighter. First of all, try connecting another device and check the fuse box in the car. It is possible that the one that is responsible for supplying current to the cigarette lighter socket has burned out. If the fuse is OK, disassemble the charger plug and check the condition of the fuse.
If the battery indicator is displayed on the screen, but the charge level does not increase or even drops, it means that the cigarette lighter is receiving low current, insufficient to power a smartphone or tablet.
The device blinks but does not charge
Smartphones and tablets equipped with a color indicator flash during charging. If your indicator flashes unusually while charging (for example, it was always blue, but now it is flashing green and red alternately), and the device is discharging, the problem may be in the processor overheating. In this case, restart your tablet or smartphone in Recovery mode and try to charge it. If the situation does not improve, clean the connector and plug contacts and reconnect the cable. A continued flashing indicates that it is time to replace the battery with a new one.

Problems when charging a smartphone or tablet
The problems of modern gadgets are connected not only with the lack of charging when the cable is connected. It happens that a tablet or smartphone is charging, but then the charge level drops sharply, or the device turns off when the battery rate is 90% and stops turning on. The recommendations below will help you deal with the problem.
Charges only when turned off
After a fall or software failure, the smartphone can only accept charging when it is turned off. Solutions to the problem:
- factory reset;
- flashing the device.
If the software methods do not help, the Micro USB connector may be damaged, and the help of a service center specialist is required.
Charging but not completely
If the power indicator is displayed, but the smartphone does not show a 100% battery level, the battery needs to be calibrated. The second reason is insufficient current for a full charge. Check the charger for cable integrity and if necessary, change to a 2-amp model with a thicker cord.
If the suggested methods do not help, replace the battery with a new one.
Not charging more than 1%
In a situation where the charge percentage does not rise more than 1%, check chargers with other gadgets and try charging your smartphone or tablet from a computer. If it doesn't help, replace the battery with a new one.
Doesn't charge until rebooted
Incorrect charging of gadgets is often associated with software. If your smartphone does not charge without rebooting or reboots during the charging process, follow these steps:
- remove unnecessary programs from the system that can affect the charging process;
- roll back to default settings;
- connect another cable;
- reflash the device.
The device runs out of power when turned off
For a working battery, it is normal to gradually reduce the charge level even when the smartphone or tablet is turned off - by about 1% per week. But if you turned off the device at night with a 100% charge level, and turned it on in the morning and saw a value of 50%, most likely you need to replace the battery. If the replacement does not work, the problem is in the processor - take the device to a service center.
The device is charging, but shows an incorrect charge value
When the charge indicator displays an incorrect value - for example, it shows 50%, and turns off after a minute and displays 0-5% when it is turned on again, battery calibration helps. To calibrate the battery:
- Discharge your smartphone or tablet. When it turns off, turn it back on and wait for it to turn off. Do this until the device starts to turn off after a second of active mode.
- Take the battery out for five minutes and put it back in.
- Connect the charging cable to your gadget. Charge it without turning it on.
- Remove the battery again for 5 minutes without turning on the device.
- Install the battery and turn on your smartphone/tablet.
If manually calibrating doesn't help, try downloading a calibrator app.
Why does an Android phone or tablet drain quickly?
Android gadgets keep the charge level throughout the day. If your device is running out of power faster and you need to extend the battery life, use the recommendations below.
What processes contribute to the discharge of the battery
The charge level is affected by screen brightness and communication modules. You can optimize battery consumption by making a number of settings. Go to device settings and disable the following features:
- 4G connection - 4G networks do not work in all regions, and when the option is connected, the smartphone is in constant network search mode;
- bluetooth - connect only for file transfer;
- wi-fi - increases charge consumption by 15%;
- gps - needed only for navigation and positioning;
- auto-rotate display - the function uses the accelerometer and gyroscope, consuming energy;
- vibration response to touch.
Close applications running in the background. If you use the launcher and themes, disable them. Also turn off automatic sync and app updates.
The device charges quickly and discharges quickly
If the smartphone is quickly discharged and just as quickly charged, the problem lies in the battery. Try to charge the phone to 100%, then discharge it until it turns off, and so on several times. If the battery does not charge better, replace it with a new one.
The device takes a long time to charge and discharges quickly
How long it takes to charge a smartphone or tablet depends on the power source. It is not recommended to use universal cables to power the device - the current strength may be insufficient and charging will be slow.
If you are using the original charger, but the battery level is growing slowly, try charging the device that is turned off. If 2-3 hours after turning off the phone, the charge indicator shows 100%, look for problems with the software. If charging the switched off gadget takes longer, the problem is in the hardware.
Charging a cold battery is slower, so do not connect the cable to the phone immediately upon returning from the cold. Wait for the machine to warm up to room temperature.
The gadget is quickly discharged in standby mode
In standby mode, the battery is consumed by the accelerometer and gyroscope. They are designed to control the movements of the device relative to the ground and the human body. To decrease the level more slowly, disable the sensors. Also close background applications. To do this, go to the "Settings" menu, select "Applications" and on the "Running" tab, stop unnecessary ones.
If the actions with the software do not help, there may be damage to the motherboard. In this case, the smartphone or tablet needs to be repaired.
Battery drops sharply
Changes in the values of the charge level do not give the user the opportunity to navigate how long the smartphone or tablet will last without recharging. If you're worried about battery fluctuations, try manually calibrating your battery or using the Battery Calibrator app.
When calibration does not help, connect a light bulb directly to the battery contacts and wait until it stops shining. Then install the battery in the smartphone and charge it to 100%. After repeating the procedure three times, the charge level will be displayed more evenly.
The charge began to sit down quickly after the update
Software updates require more power from smartphones and tablets, and therefore consume battery faster. If after the update your gadget began to discharge faster, perform a factory reset, after saving important information.
Another common cause is a virus that got into the phone with an update. Find the virus program and remove it. To do this, use an antivirus - Kaspersky, McAfee or Dr. Web.
How to check battery status
There are various ways to check the battery status.

A working battery will make a couple of turns and stop, and a worn one will spin for a long time. |
During charging, you can see a question mark on the battery icon - it appears when the battery is worn out, notifying you of the need for replacement, or in cases where the plug contact comes off.
How to charge an Android device with a broken connector
Charging problems are often associated with a broken Micro USB connector. If it is out of order, and you need to extend the life of the gadget, use a wireless charger. Attach the receiver to the battery and turn it on. After an hour, the battery will be charged.
In extreme cases, the battery can be charged directly from the power cable. To do this, just cut off the plug, connect the wires to the contacts and plug the power supply into the outlet. Do not use this method if you are not sure of your knowledge of electrical engineering, and if you do, constantly monitor the charging process.
How to properly charge Android devices
To prolong battery life, charge it properly. The method of charging depends on the material from which the battery is made. Lithium-ion batteries charge up to 100% and discharge completely, and recharge lithium-polymer batteries as needed. Other rules for charging smartphones and tablets:
- Do not leave a charged gadget connected to the cable. After the battery is 100% saturated, turn off the power.
- Use original power supplies from manufacturers.
- Do not charge the device when you return from the cold.
Charging problems usually occur for users a year or two after buying a smartphone or tablet. If you notice a problem from the moment you purchased the device, before repairing it yourself, contact a service center where the gadget will be repaired or replaced under warranty.
