The phone shows that it is charging. What to do if your phone won't charge: practical advice

So yours smartphone or tablet started showing 1% charge. In particular, some Meizu smartphones are guilty of this, including my Meizu M2 Mini. What to do in this situation? I will tell you using my own situations as an example.

This problem can be either software or hardware. Software problem It is possible to solve, but with the hardware it will be more difficult.

So how did I solve the 1% charge problem?

Method 1. Hardware solution to the problem.

First of all, I charged the smartphone, even if it showed only 1%. I knew that for fully charged About two hours will be enough for me. Accordingly, he had to stand charging for that long. Turn off your device (this is important) and put your smartphone on charge and let it charge a little.

After two hours, try turning it on. In one of the cases, the correct battery charge was immediately shown to me. Only you know how it will work out for you, but if nothing works out for you, then you should wait until the phone or tablet is discharged to zero again and turns off. Then put it on charge again.

This method will help solve a hardware problem with the battery by calibrating it. But if your battery is already “many years old,” then this method may not help at all. All you have to do is replace the battery with a new one.

Method 2. Software solution to the problem.

The problem with 1% battery charge may also be software. In particular, I rebooted my Meizu smartphone several times so that it began to show the correct battery charge, but only resetting the smartphone to factory settings helped me.

If, after resetting the settings, nothing worked for you, then the battery needs to be replaced. Also, for some users, it happens that the smartphone is charging only half or is gradually charged to a lower value. Again, in Meizu smartphones there is a situation when The smartphone does not charge above 70%. Calibrating the battery will help here, although partially. After some time, the problem returns and a complete battery replacement will be required.

Some users tell me that they have non-removable battery . By the way, if anyone is interested, go read it. So, all smartphones have a removable battery. It’s just screwed to the body and sometimes it’s quite difficult to unscrew it, and at home it’s often impossible. Plus, when disassembled, you will lose the warranty, if any. In such cases, the battery will need to be replaced service center.

Quite often users mobile devices They are faced with one not very pleasant problem - the phone is discharged while charging. The reasons for this can be completely different, as well as ways to eliminate them. In this article we will try to consider everything possible options why the phone discharges when charging, and how you can deal with it.

Faulty charging socket

The most common reason why a phone dies while charging is a faulty charging socket. This situation occurs quite often, especially when the voltage is unstable or there is a manufacturing defect. "Symptoms" are standard:

• The phone displays an indicator that charging is in progress or there are no indications at all.
• After some time, the phone does not gain charge, but, on the contrary, spends the remaining one.

And although some of the described “symptoms” will appear more than once during the course of the article, in in this case everything points precisely to a faulty charging socket. To finally make sure that the socket is broken, you need to try connecting the phone to a different outlet and changing the charger to eliminate its malfunction. If nothing has changed, you can proceed to repair.

Elimination

In order to fix a faulty charging socket, you can go to a service center, but only if the phone is under warranty. There it should be accepted without any problems and repaired within a few days, although everything depends on the service center itself.

If your phone is already out of warranty, contact any well-trusted mobile phone repair shop. Repair times are usually much shorter than in a service center, and the quality of work is approximately the same.

Another option is to change everything yourself. Fits this method only to those who are well versed in soldering and have the necessary equipment.

The charging socket is oxidized

The next reason why the phone discharges while charging is the oxidized connector for the charger. The reason is primarily moisture getting into the charging socket, for example, through wet hands or rain, perhaps water spilled near the phone and got on the contacts. Another reason for oxidation may be the banal and harmful habit of taking a smartphone with you to the bathroom. This is not recommended, because the bathroom is a room with high humidity. The only exceptions are those phones that are protected from moisture.

Signs that the charger socket on your phone has oxidized are as follows:

• The charger is connected.
• The screen shows an indicator that charging is in progress.
• After some time, the battery charge did not increase, but rather decreased.
• The phone became noticeably warm in the area of ​​the charging socket.
• The charger plug is hot.
• Upon visual inspection, there is an extraneous characteristic coating on the contacts and the socket itself.

By the way, not only the connector on the phone itself can be oxidized, but also the charger plug, so this also needs to be taken into account.

Elimination

There are several ways to eliminate c oxide, but they can be divided into two groups - temporary help and a 100% solution.

Temporary

A temporary method involves cleaning the contacts from oxide yourself. It is called temporary because the oxide will sooner or later appear again, and the procedure will have to be done again. Besides, this method does not guarantee 100% success.

To clean, you will need a very thin needle or any other sharp object, a small piece of cloth and soda. You need to secure the fabric at the tip of the needle so that it does not slip and fits into the connector. After this, you need to slightly wet the cloth, dip it in soda powder, place it in the charging socket and clean everything as much as possible.

Replacement

Since the effectiveness of the first method is not very high, and the problem itself is not eliminated 100%, the only correct method is to replace the socket. This can be done through a workshop or independently.

Faulty charger

Another reason why the phone is charging and discharges is a banal malfunction of the charger itself. The fact is that it is enough for just one wire somewhere inside the cable to break - and that’s it, a full charge will not flow. There is no point in describing the symptoms here; just check the charging operation on another phone or connect your phone to a working charger.

Elimination

Eliminated this problem easy and fast, just buy a new USB cable or completely change the charger.

Burnt board

A burnt socket board is the reason why the phone runs out of power while charging. In this case, the socket itself may be fine, but the board on which it is installed sometimes burns out or fails. With such a breakdown, the charging indicator does not appear, but if the corresponding icon does appear, the phone will simply discharge.

Elimination

This breakdown can be eliminated only by completely replacing the circuit together with the charging socket. You can do this in any service or yourself.

Fast discharge

A common problem is that after charging the phone discharges, and quite quickly, within an hour or a little more. The main and only reason for this is faulty battery, which has exhausted all its resources.

Elimination

This breakdown can be fixed quickly, you don’t have to send your phone for service - you only need new battery for the corresponding phone model.

If your phone's battery isn't charging properly, don't think it's just the battery or the charger that's causing the problem. Based on personal experience, the problem and its solution may be much simpler than you think. If your smartphone or tablet is charging poorly or not charging at all, then check out 10 ways to fix these problems.

Why is the device not charging?

Problems arise to varying degrees. Either the phone doesn't want to charge at all when it's connected, or the process is too slow. Here are some solutions for you.

1. Poor contact

Very often the metal coating inside the USB port and micro USB It has bad contact, either through a manufacturing defect or through cable wear.

All you need to do is turn off the device, remove the battery if possible, and clean the contacts inside with something like a needle or toothpick. Do this very carefully and carefully, then insert the battery and connect the charger again. 9 times out of 10, that's all you need to do.

2. Clean the charging port from dust and foreign fibers

Do you keep your phone in your jeans pocket? If so, then fibers could be the culprit behind the problem: we've lost count of how many times it's caused faulty charging became the fibers of our clothes.

You can also return the charging connector to normal condition by blowing it with compressed air.

3. Try a different cable

The most fragile part of the charger is the cable. It constantly bends, which can damage it over time.

The easiest way to diagnose a damaged cable is to take another one and see if it works properly with your device. If yes, you know that original wire charger is faulty. If not, then you need to look for a solution further.

4. Use a different adapter

You have ruled out problems with the cable, then you need to check the functionality of the charging device itself. This is much easier if you can pull the wire out of the adapter. We've encountered many chargers where the USB ports have become worn out due to endless plugging and unplugging of the cable.

Also check the charging/wire functionality on other phones as this will help rule out the possibility that it is a problem with your smartphone. In addition, you must make sure that the outlet is working properly.

5. Remember - safety comes first

Do not charge your device near water or in extremely hot or humid conditions. Do not keep the device connected to the charger for too long. Don't leave it charging overnight when it only needs 2-3 hours. This may cause damage hardware.

If you want to replace the charger or its cable, be careful: cheap third-party adapters are quite dangerous. Behind Lately There have been many cases of mobile phones catching fire due to them.

The video below captured one of these cases:

6. Replace the battery

Life battery does not last forever and after a few years of use it loses its capacity. The more often you charge and discharge it, the sooner it will deteriorate. Of course, if the battery stops working after six months of use, then you need to contact the seller for a warranty.

Some defective batteries can be easily identified by appearance. If it is swollen, then it should be replaced immediately.

7. Charge from the correct source

Charging from a wall outlet will always be faster than from a computer because its USB ports have too little power. Thus, the phone charges much faster from a power outlet.

The problem may also be that you are using an adapter from another device, for example, from a Bluetooth headset, which is not intended for your gadget. This adapter does not supply enough current. When latest models smartphones high class, you may have a device that supports fast charging, but the adapter is not suitable.

8. Update the software or roll back to the previous version

Updates software may degrade battery life mobile phone, especially when the old device gets a fresh one Android version. Newer smartphones and tablets are often optimized for benefits latest version BY.

If this happens to you and you can't find a solution, try rolling back to previous version. Of course, you can try first full reset, as recommended by manufacturers, so as not to compromise the data on the device due to old version Android.

Likewise, sometimes autonomous operation smartphone can be significantly improved with a fresh update.

9. Try turning it off

Using heavy applications while charging affects the duration of the process. For example, if you are chatting on Skype or playing games, the device will take longer to charge.

Therefore, charge the device in the off state or in airplane mode.

10. Calibrate the battery

Sometimes, the battery charge level displayed on the screen may differ from the actual battery level. Because of this, your phone's behavior may seem strange to 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 connecting the charger ( Charger) the display shows information 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 - perhaps 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 has only 3 bolts that hold motherboard. 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

According to reviews from service center workers, charging problems are one of the most common reasons to contact them. Sometimes this is due to really serious problems, such as a failure of the power controller, which requires replacement of components. But most often, problems with charging the device can be solved yourself. Here is a list of steps, in order of increasing difficulty, that you can do yourself before calling a repair shop.

1. Remove debris, dust and grains of sand

If you never part with your smartphone for a minute, carry it in your jeans pocket and carry it to the sea, then sooner or later charging socket the gadget will accumulate so much garbage that it will completely refuse to charge. Therefore, first of all, carry out visual inspection USB port. Then blow it out with a can of compressed air and gently brush it with the bristles of a stiff toothbrush.

2. Clean the USB port contacts from oxidation

Sometimes the device does not charge due to oxidation of the contacts. This happens especially often if the smartphone has not been used for a long time or is used in unfavorable climatic conditions. In this case, cleaning the contacts with a toothbrush dipped in alcohol or even a thin needle can help you out. Do not forget to first turn off your smartphone and remove the battery from it, and perform the operation itself as carefully as possible.

3. Replace the cable

The next weak link to check is the USB cable. Their lives are often full of trials and hardships, so it is not surprising that some of them may die without any warning. The easiest way to check this problem is to take a known working cable from another device and connect it to your gadget. If the problem persists, then proceed to the next step.

4. Test the power adapter

The charger is also often a source of problems. We are talking about that very small box that is plugged into an outlet. First of all, touch it to check the temperature. An adapter that is too hot, like one that is too cold, can serve as an indirect sign of failure. Make sure the cable connection is in good condition and clean it if necessary. Try to find another power adapter that suits your specifications.

5. Buy a new battery

Modern technologies have made batteries much more durable than before, but still not eternal. Each battery has its own lifespan, expressed in maximum quantity charge and discharge cycles. If you use your gadget intensively and it is already several years old, then it is likely that the battery life is running out. To check this, simply take it out and make sure there are no bulges, smudges or other signs of aging. However, it is most reliable to check the voltage supplied by the battery using. If it is too low, then you should look for a replacement at a service center or online stores.

6. Do a factory reset

If you have gone through all the steps and none of them helped you figure out the cause of the problem, then perhaps the problem is software glitch. operating system Android collects device usage statistics in order to prevent the battery from being completely drained. In some devices, a full discharge causes the built-in power controller to malfunction, which in turn prevents the device from accepting a charge as usual. In this case, resetting the device to factory settings may help (remember to do this first backups important data). Of course this last resort and you need to resort to it only if you have already tried everything else.

In this article, I tried to describe the most common problems with charging gadgets and ways to solve them. Of course, in real life there may be many more of them. Write about the cases you have encountered in the comments.
