What to do if the phone battery stops charging

Frequent cases of contacting specialized services with a fully discharged smartphone battery. Users are puzzled to turn to specialists with an "extinct" phone, but is it worth it? Is it possible to eliminate such a problem yourself? What to do if the battery on the Android phone is not charging? We will understand in this article.

Kinds of problems

Problems with charging can be divided into two types: problems with the charger, phone accessories, or a fully discharged battery. With the first case, everything is clear, we replace the damaged elements and deal with the end, but the dead battery can be completely working and not be charged, so we will first deal with the components, and then with the manipulations that can revive our battery.

IMPORTANT. All manipulations must be performed with the phone turned off, disconnected from the network.

Problems with the phone or charger

Dust, debris or oxide

With intensive use of the device, contamination or oxidation of the contacts is almost inevitable both for connecting the battery and for connecting the charger. First of all, we remove the back cover, take out the battery, if possible, we clean the contacts. We do the same with the USB-out, we also check if there is any garbage there.

Mechanical damage

We got the battery, carefully consider it. If there is a bulge, the battery is swollen - urgently changed, in no case to connect to the network.

Comparison of normal and swollen battery

We look carefully at the USB output. If there is any physical damage, change the same. If the tongue is slightly oblique or crooked, then you can try to return it to the desired position with a flat screwdriver or other similar tool.

If the problem with charging appeared after mechanical damage, such as falling or hitting, then you will most likely have to carry the device to a service center to specialists.


Usually, if the phone battery is not charging, they sin on the charger, and rightly so. Elementary damage to the wire may cause you to buy a new cable or charger. The charger itself can burn out, often it happens, but there are some nuances.

It is advisable to charge Android with a native charger.

If for some reason you are using a non-native device that produces an insufficient number of amps, then your battery will inexorably lose its charge until it is completely exhausted, but more on that later. In the most general case - use either a native charger, or similar, pay attention to the output current.

If the charger looks fine and the current for our phone is suitable, then try to charge them with another phone. Depending on the success of the work done, either read the article further, or change the charger.

Low Battery Syndrome

The new battery for the phone is not charging? Let's figure it out. In any phone there is a special controller that will refuse and forbid charging the battery, the voltage on which fell below 3.5 V. Therefore, you should not run feverishly and buy a new battery if it does not want to charge, it is quite possible that it is too low. The native charger will not help in this case, we need another power source.

Using a device with free terminals

A universal solution can be considered a "frog". This is a charger with free terminals, you can connect almost any battery to it. It is unlikely to fully charge a serious battery, but we don’t need it, we need to catch up with the battery voltage above 3.5 V. In case the frog isn’t near, you can use any other charger, having previously calculated what current we need will need, and creating additional resistance, if necessary. We will not go into details, the average user is hardly capable of this, and the one who is capable does not need instructions. In any case, it would be nice to have a multimeter with you, charge our battery in any way possible and measure the voltage on it. If there is no multimeter, we set the battery to charge for a decent period of time, after which we experimentally check to see if our beauty “came to life”.

In most cases, the phone will boot with a restored battery, but it can and will not charge. In which case? Again, we check the current on the charger, which we connect to the phone. If the amp is not enough - replace it with a suitable one that matches our native charger.

If the problem is not resolved, then check the iron for conductivity. We disassemble the phone, we need to get to the USB-port and ring it. There can not do without a multimeter. Minus leaning against the skin of the port, and plus to the capacitor, as shown in the figure.

Check USB port multimeter

If the current does not pass, you will have to replace the port yourself or contact the service center. Further, in principle, it makes no sense to climb myself, so here we stop.


So why not charging the battery on the phone? The reasons can be a huge number, and not all problems can be eliminated without special training and equipment. Small problems that are usually solved by diagnosing and replacing some parts or components are simple. Problems with the board can be an impossible task for the average user. Contacting a certified center can hit your pocket, but you will definitely get a competent answer to any question, fix your device and save a lot of time.
