What to do if the tablet is not charging. The tablet is not charging - what to do?

Facebook

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 suddenly drops its charge level, quickly discharges, loses battery charge when connected to an outlet, or completely stops responding to the charger being connected. If your smartphone has stopped charging, explore the possible causes and solutions to this situation.

What to do if your Android phone or tablet is not charging. Possible reasons

Common reasons for lack of charging are a breakdown of the power supply or MicroUSB connector, battery wear, or software failures. When you realize that your smartphone or tablet is not charging, first check the voltage at the contacts of the battery and charger. If everything is fine, use other methods to restore your smartphone or tablet.

Shows that charging is in progress, but is not charging from the mains

If, when connected to an outlet, the indicator shows the charging process, and when you disconnect the cable, the smartphone or tablet turns off, the charge level controllers are probably shorted. A short circuit occurs as a result of water getting inside 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 service center. Specialists will detect and replace the faulty element.

The charging percentage does not change via USB from the computer

Users often charge smartphones and tablets from a laptop rather than from a wall outlet. Reasons why a smartphone, with a working battery, does not receive power from the computer:

broken or insufficient cable thickness;
insufficient current for charging;
the connection is blocked by the PC operating system;
The “USB charging” function is disabled in the device menu.

If you find a break in the wire, connect the two broken ends together and rewind with electrical tape. If the current supplied to the USB port is not sufficient to charge, try connecting the device to a different port.

The Ubuntu operating system blocks charging more often than others. To bypass the blocking, blacklist your smartphone at /etc/default/tpl.

Completely discharged and won't charge

Smartphones and tablets do not respond to connecting the charger when deep discharge battery If the gadget was discharged more than a day ago and shows no signs of life, connect it to an outlet and leave it turned off. After 10 minutes, check if the charge indicator lights up. If yes, you can turn on the device.

If the indicator does not light up, clean the Micro contacts USB connector and the plug on the charger cable. Take a thick needle and use the opposite end to remove small dust particles and pellets. Insert the plug into the connector and leave the smartphone or tablet for another 10 minutes.

A common situation when users suspect charging problems is a broken display. At the same time, the gadget is charging, but you don’t see it - the screen remains dark. To check whether charging is in progress or not, use the light indicator on the case. If there is no indicator, turn on the device. If the display breaks down, you will hear a characteristic system startup sound, and if the charging connector does not work, the gadget simply will not turn on.

Stopped charging from the cigarette lighter

When charging your smartphone in a car, you may encounter the problem of a lack of charging from the cigarette lighter. First, try connecting another device and check the fuse box in the car. Perhaps the one 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 and even decreases, it means that the cigarette lighter is supplied with a low current that is insufficient to power the smartphone or tablet.

The device blinks but does not charge

Smartphones and tablets equipped with a color indicator blink while charging. If your indicator blinks unusually when charging (for example, it was always blue, but now blinks green and red alternately), and the device is discharged, the problem may be that the processor is overheating. In this case, restart your tablet or smartphone in Recovery mode and try charging. If the situation does not return to normal, clean the connector and plug contacts and reconnect the cable. Continued flashing means it is time to replace the battery with a new one.

Problems charging a smartphone or tablet

Problems modern gadgets are associated 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 level is 90% and stops turning on. The recommendations below will help you cope 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. Options to solve the problem:

reset settings to factory settings;
reflashing the device.

If software methods don't help, maybe it's damaged Micro USB connector, and assistance from service center specialists is required.

Charging, but not fully charged

If the power indicator is displayed, but the smartphone does not show a 100% charge level, battery calibration is necessary. The second reason is insufficient current for full charge. Check Charger check the integrity of the cable and, if necessary, change to a two-amp model with a thicker cord.

If the suggested methods do not help, replace the battery with a new one.

Doesn't charge more than 1%

In a situation where the charge percentage does not rise above 1%, check chargers with other gadgets and try charging your smartphone or tablet from a computer. If that 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 restarting or restarts while charging, follow these steps:

remove unnecessary programs from the system that may affect the charging process;
roll back to standard settings;
connect another cable;
reflash the device.

The device discharges when turned off

It is normal for a working battery to gradually decrease its 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 reading of 50%, the battery most likely needs to be replaced. If the replacement does not produce results, 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 after a minute it turns off and displays 0–5% the next time it is turned on, calibrating the battery helps. To calibrate the battery:

Discharge your smartphone or tablet. When it turns off, turn it back on and wait until it turns off. Do this until the device begins to turn off after a second of active mode.
Remove the battery for five minutes and install it back.
Connect charging cable to the 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 the smartphone/tablet.

If manual calibration does not help, try downloading a calibrator app.

Why does my Android phone or tablet run out quickly?

Android gadgets maintain their charge level throughout the day. If the device discharges faster and you need to extend the operating time of the device, use the recommendations below.

What processes contribute to battery discharge?

The charge level is affected by the brightness of the screen and communication modules. You can optimize battery consumption by making a number of settings. Go to your 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 search networks;
bluetooth - connect only to transfer files;
wi-fi - increases charge consumption by 15%;
GPS - required only for navigation and location determination;
auto-rotate display - the function uses the accelerometer and gyroscope, consuming energy;
vibration response to touch.

Close applications running in background. If you are using a launcher and themes, disable them. Also disable automatic synchronization and application updates.

The device charges quickly and discharges quickly

If your smartphone discharges quickly and charges just as quickly, the problem lies in the battery. Try charging your phone to 100%, then discharging 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

The charging time for a smartphone or tablet depends on the power source. It is not recommended to use it to power the device universal cables- the current may be insufficient and charging will be slow.

If you are using an original charger, but the battery level is growing slowly, try charging the device while it is turned off. If 2-3 hours after turning off the phone the charge indicator shows 100%, look for problems with software. If charging a 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 after returning from the cold. Wait until the device warms up to room temperature.

The gadget quickly discharges in standby mode

In standby mode, the accelerometer and gyroscope consume the battery. They are designed to control the movement of the device relative to the ground and the human body. To make the level drop more slowly, turn off 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 actions with the software do not help, there may be damage to the motherboard. In this case, the smartphone or tablet requires repair.

Battery charge drops sharply

Changes in charge level values do not give the user the opportunity to determine how long a smartphone or tablet will last without recharging. If you're concerned about battery level fluctuations, try calibrating your battery manually 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 drain quickly after the update

Software updates require more energy from smartphones and tablets, which means they drain their charge faster. If after the update your gadget begins to discharge faster, reset the settings to factory settings, first saving important information.

Another common reason is a virus that got into the phone with the update. Find virus program and delete it. To do this, use an antivirus - Kaspersky, McAfee or Dr. Web.

How to check the battery status

Exist various ways checking the battery condition.

Name of the technique	Implementation
Digital Team	· *In dialing mode, enter the combination ##4636##* and select “Battery Information”.** · use the Battery application - it displays information about the battery status: voltage, temperature and other parameters.
External inspection (if the battery is removable)	· Disconnect the battery and inspect for any bulges. If the battery is swollen, it means it is faulty and requires replacement. · If there are no visible irregularities, place the battery on a table and twist it. A working battery will make a couple of revolutions and stop, but a worn battery will spin for a long time.

During charging, you may see a question mark on the battery icon - it appears when the battery is worn out, indicating 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 fails and you need to extend the operating time of your gadget, use a wireless charger. Attach the receiver to the battery and turn it on. In 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 confident in your knowledge of electrical engineering, and if you use it, constantly monitor the charging process.

How to properly charge Android devices

To extend the life of your battery, charge it properly. The charging method depends on the material from which the battery is made. Lithium-ion batteries charge to 100% and discharge completely, and recharge lithium-polymer as needed. Other rules for charging smartphones and tablets:

Do not leave a charged gadget connected to the cable. Once the battery is 100% saturated, turn off the power.
Use original power supplies from the manufacturers.
Do not charge the device after returning from the cold.

Users usually experience charging problems a year or two after purchasing a smartphone or tablet. If you notice a problem since purchasing the device, before repairing it yourself, contact a service center where the gadget will be repaired or replaced under warranty.

Today, tablets are extremely popular, which is not surprising - for many users they have replaced computers and laptops. Indeed, why do you need a massive device when a lightweight tablet can replace it? You can surf the Internet, play games and even work on your tablet.

Tablets, like any other electronic device, can experience problems. For example, the tablet may simply stop charging. Why does this happen and what to do in this case?

Reboot your device

The very first thing we can recommend in such a situation is to reboot the device. There may be some kind of failure in the system and a reboot will fix the problem. Please note that on some tablets there is no reboot as such: you first need to turn off the device, then turn it on again.

Change your charger

If the reboot does not work, the problem may be with the charger. If possible, use a different charger. If it charges your tablet, great.

It should be noted that chargers can fail. For example, quite often there are cases when charging works at its own discretion - today it does not want to work and charge the device, but the next day it works as before. It is better to replace such a charger, as it can damage the tablet.

By the way, although the chargers themselves are inexpensive, it is better to use original ones, but they are much more expensive.

Check the cable

It is also worth paying attention to the cable, and not just the charger. This is especially true in cases where you have pets who are not averse to eating wires.

In this case, everything is simple - replace the cable with a new one and see if the tablet is charging.

Clean the contacts

It often happens that there is voltage, the current is normal, and the LED on the charger lights up, confirming the fact that charging is in progress. Only the tablet itself does not charge. In this case, you should check the contacts - a lot of dirt can accumulate in them. Cleaning your contacts may help.

At the same time, move the connector, perhaps this is the problem. This may be due to some contact coming loose.

Charging the tablet from the computer

Sometimes users complain that the tablet does not charge from the computer, but charges from the charger. Why? This is due to the fact that tablets really are not always charged from a computer, because they simply do not have enough power. There are no such problems with the charger. Just accept it as a feature.

Connect the charger and wait

If all else fails, try connecting the tablet to the charger and leaving it like that for an hour or two. Perhaps after some time it will start charging. It’s difficult to say exactly what this “amateur activity” involves, but the method works, believe me.

Reflash your tablet

In exceptional cases, the problem may be software related. It is recommended to either roll back the device to its original state or reflash (update) it.

Let us repeat, this happens in rare cases.

The tablet won't charge or turn on

In what cases should you contact the service center?

If you dropped your tablet and now it won't charge or turn on.

If the tablet does not charge due to a faulty power controller.

If none of the described methods helped you.

It's coming in the yard New Year, New Year's advertisements began to air on TV, but the stream of broken mobile technology does not decrease. Recently they came again to repair the tablet. Symptoms of the malfunction are such that when you connect the charger (Charger), information is displayed on the display that charging in progress. But in reality it is not there - you can follow this process and see: the percentage numbers do not rise, but gradually fall, just as without a connected memory. From all this we can say that the power control chip is working normally, well, if not normally, it will do, the tablet turns on and displays charge and discharge. Then I started thinking - maybe the field workers were covered, in the photo the transistors are circled in blue, I also highlighted the MT6323 power management chip.

Then another symptom was discovered: when OTG connection The cable does not work, or rather the USB mouse did not work, even power was not supplied to the mouse, there was definitely a break in the power circuit, but it was not possible to trace the tracks. I started calling with a multimeter, but it was of little use.

Next, I decided to look for limiting resistors - they are the largest and the value is usually up to 5 ohms. I found one of these, measured the resistance, and it showed 5 kOhm! The markings were erased, everything was in the old Chinese style, I first replaced it with 100 Ohms - no result, but the voltage at the battery terminals rose to 2.5 volts - that's already something. Then I set it to 10 ohms - it seemed like it even started charging, but this was clearly not enough, then I decided to set it to 1 ohm, but I didn’t have such a resistor, so I just shorted it with a wire, as shown in the photo, hurray - everything works, the charge is coming, OTG cable works USB mouse discovered and it works well!

But the repair was not completed, my network was not working, then I found an antenna in the form copper wire in isolation, I saw the inscription “GSM” on the board near the coin. Yes, we are at the address, by the way GSM WIFI GPS antennas all are soldered to the ground, so there is no point in soldering an antenna for GSM, then another one for WIFI GPS - they are all connected, but I think that this is not the case for all phones and tablets - it is better to call. We solder the wire and see that our tablet has already begun to catch the network.

At this point the repair is complete, I also forgot to say that the flux needs to be washed off later, I forgot to take a photo and already assembled the tablet, but you need to wash it with the battery and charger disconnected, so as not to do it by accident short circuit. I didn’t want to take it apart again, since everything here was fastened with latches, and this tablet only has 3 bolts that hold the motherboard in place. Thank you for your attention and as always I was with you Kalyan.Super.Bos

Discuss the article IF THE DEVICE SHOW CHARGING BUT IS NOT CHARGING

The tablet suddenly stopped charging or is charging incorrectly (too long, not completely, discharges quickly after fully charged etc.) – what to do in such a situation? First, calm down. Secondly, familiarize yourself with the possible causes of such changes, available home remedies for eliminating them, and useful accompanying recommendations. This is what you are asked to do next.

Why might my tablet stop charging?

Helpful advice! First check whether the adapter charges another tablet and whether the battery of your gadget is replenished when you connect a third-party working charger to it - this will narrow down your search.

A complete list of reasons why the tablet may stop charging is given below.

1. Problem with the cable. The most common reason. Do you store wires tightly wrapped? The result is obvious. Most often, the wires become bent and break where the cable enters the charger plug. You can try to solder the damaged contacts yourself, but it’s better to immediately buy a new cord - such patches still won’t last long.

2. Problems with the adapter. An equally common reason. Most often it occurs among users living in apartments/houses with unstable power grids. To solve this, again, you will have to buy a new adapter.

3. Battery failure. To check its functionality, just connect another working charger to the tablet. If the battery does not respond, you will have to buy a new one, because... Repairing an existing one will lead to a significant decrease in its reliability, and not every master will agree to take on such work.

4. Connector failure. Again, you can check by connecting a 100% working charger to the tablet. The solution comes down to replacing the port. Can be done in any specialized workshop.

5. Problems with the power controller. This element of the tablet’s internal “stuffing” is responsible for the operation of the power system. If it breaks down, the battery will not be charged or its reserves will not be replenished correctly.

6. Problems from outside operating system. IN in this case Either resetting the settings to factory settings or flashing the device will help.

What to do with a tablet that won't charge?

As noted, you can find the problem that led to the breakdown in question using the method of elimination.

The problem may be not only in the adapter and the device itself, but in your network, for example, low voltage or unstable voltage in the network. All this can damage the charger, as a result of which it may not work correctly or even burn out.

If you have a voltage meter at home, then you can check the “current” according to the instructions below, but be careful!

First, measure the voltage in the network. A multimeter will help you with this. If the voltage deviates from the recommended 220V by more than 5V, the functionality of the charger may be impaired (it will not have enough power or it will burn out), which is why the tablet will stop charging.

Using the same multimeter, check the output voltage on the charger and compare it with the numbers given on the adapter body. Deviation of indicators above acceptable limits indicates a breakdown of the adapter.

Next you need to check the voltage at the cable output. To do this, connect it to the adapter and test it with a multimeter. If the cable output has a lower voltage than the adapter output, the problem is the former. Additionally, you can ring the cord. If it rings, everything is fine. You can check the cable without this device - just connect the tablet to your computer/laptop through it.

Is everything ok with the adapter and cable? Resetting the settings didn't help fix the situation? The problem is with the tablet hardware. Only a qualified service center employee will help solve it.

If it turns out that the cord/adapter is broken, simply buy similar new components, and very soon your tablet will “come to life” and will delight you again!

Today, some users simply cannot imagine how they can live without mobile phones. Modern world simply obliges one and all to be “electronically equipped.” Information for us people has become a kind of drug, and a tablet that has stopped functioning becomes for the user global problem. “Why isn’t my tablet charging?” - one of the most common questions among those who own such a wonderful device. The article you are reading is intended to help solve some difficult situations and is a valuable practical guide.

So, with a 40% probability the reason lies in the charger

Yes, it is the power supply, through which you “refuel” the battery capacity of your electronic assistant, that is most often the culprit for the question that arises: “Why is the tablet not charging?” First of all, you need to measure output voltage on the charger: tester or multimeter in this irreplaceable helpers. If the displayed value does not correspond to the charger rating (information on the case), the charger needs to be replaced. For people who are familiar with radio electronics firsthand, it will be enough to repair the power supply, because in this case, most likely one or more capacitors have failed.

The second possible reason when the tablet does not charge

What to do and how to solve the current problem if the first method did not have an effective effect?

Pay attention to the integrity of the structural elements of the device’s charging connector. Inadmissible points: play, instability and deformation of the input element located on the tablet’s motherboard. You can verify that it is working as follows:

It is enough to move the limit switch of the charger when it is in active state(connected to the tablet and the mains). If a charge indicator appears during manipulation, the problem can only be corrected by replacing the gadget socket or the contact device included in it. In most cases, it is the device’s connector that becomes unusable, since the owner often uses the tablet at the time of “refueling” battery capacities, bending and stretching the connecting cord, thereby disrupting the moment of fixation of the charger end switch in the device socket.
A visual inspection of the inside of the connector can resolve the question of why the Samsung tablet is not charging, since most often the reason lies in the positioning of the contacts, which become stuck and bent as a result of careless actions of the owner of the device or when devices of the wrong type and purpose were inserted into the connector. The centrally located pin contact can be bent or pressed into the gadget. Such a violation can only be corrected in a specialized workshop, since the process of disassembling the body part is inevitable.

The third group of malfunction symptoms

Sometimes the question “why is the tablet not charging” may be related to the residual manifestations of liquid, dust or other foreign substances that have gotten inside the device. The most dangerous and capable of critically influencing working condition tablet is water. The oxidation process destroys the integrity of the solder joint and can cause a short circuit. It should be noted that minor manifestations of corrosion on the contact elements of the device can be removed independently: cleaned or washed with alcohol. And yet, if external traces of destructive properties are detected, the tablet must be subjected to specialized diagnostics. Prevention in the form of inspection of the internal hardware of the device is highly desirable, because local type oxidation tends to spread to components and parts located directly nearby. By the way, the harmful effects of water in the form of steam or condensation may also be the reason for another quite popular question: “Why does the tablet take a long time to charge?”

Four signs of the same type of breakdown

If your gadget quickly discharges even after a slight load, you should pay attention to this fact Special attention, and not condone the increased “appetite” of the battery and frequent charging sessions. It's time to replace your pet's battery. What could this be connected with, since your tablet is not even a year old? Cross question: “Why does the Samsung tablet take so long to charge?” will become a kind of guideline that will allow us to determine the main reason, so to speak, to find the absolute culprit of the two incidents.

1. When 220V is a necessity

A banal lack of proper voltage in the network can be the essence of the problem, when the device “refuses” to charge, or the “recharging” process turns into a “protracted leap into nowhere.” Turn off household electrical appliances that are the most power-hungry. These can be considered various heating equipment and power current consumers. Then measure the voltage in the network and check whether the tablet is now charging.

2. Hardware culprit

If the tablet takes a long time to charge and gets hot rear end panels - the power controller has “decided to live for a long time.” A critically unpleasant moment associated with the need for specialist intervention and the use of professional equipment. It is possible to restore the functionality of the microcircuit (controller) by thermal positioning and putting it in place. Often the cause of such a malfunction is the moment of shear, displacement or separation of the part from the original contact pad after a significant impact or fall.

3. The importance of the right team

Software failure is least likely to be the source of the problem. Sometimes the tablet software becomes a kind of intermediary of incorrectly processed commands, thereby disrupting the course of energy management of the device. Reflashing or updating the software of the device will help fix this type breakdowns.

4. Special Offender

The “most popular” reason why the tablet takes a long time to charge can be considered However, possible malfunctions We will devote a special chapter to this particular element of a modern tablet’s configuration.

“Fuel” must be supplied to the system stably

It's no secret that correctly redistributed Electric Energy can be significantly saved by a device that uses and implements a special energy-saving power management scheme.

Agree, why bright lighting when sunlight or loud music in a quiet environment? So, after it has become obvious to you that the tablet is not charging, what should you do in such a situation? Let's still focus on the direct source of energy, so necessary for full and efficient work your tablet. Incredibly, it can most often fail the owner of a portable device. Of course, the fault of the battery is a somewhat exaggerated definition. Most often, it is the person who forgets to promptly “fill” the battery’s capacitive reservoirs with “life-giving” energy or who performs energy maintenance incorrectly electronic device. When a gadget is not used for a long time (for example, waiting for a birthday), being someone’s gift, then in such a situation, the question “why is the tablet not charging” will become a natural consequence of not entirely correct storage. Battery at deep discharge It may simply not respond to the charger, or after some time it may still “wake up”, so to speak, become active. It is very important, when dealing with the issue of operation and maintenance of the compact “electronic assistant”, to observe a number of simple rules, in order to avoid the occurrence of sometimes unjustified situations when the Samsung tablet does not charge due to a failed battery.

Avoid systematic deep discharges.
Connect the charger only when the battery has no more than 20% of the total energy potential.
When “refueling” from electrical network do not use a tablet.

Finally

Along with the speed, power and elegance of the outline of the body frame, a modern device must meet the parameters of efficiency, which, in turn, should not affect the efficiency of the device in operation. As a result, the energy consumption of the gadget simply must be minimal. That is why the battery of trendy tablets is the most important element that ensures comfort and reliability while using the tablet.
