What causes the charger to not charge

Under normal circumstances, if the mobile phone does not respond after plugging in the charging cable, there are two possibilities. One is that the system has a problem, and the other is that the charger or the mobile phone battery is faulty. Then the mobile phone charger What should I do if I can't charge it? The experts of the Qiqi charger manufacturer teach you to find out why you can't charge.

1. The mobile phone can't be charged. Of course, we need to find out which part is out of order. Only when we find the problem can we take the right solution. Below I step by step to check what is the problem from simple to difficult.

2. Change a cable or a charging plug, and then recharge to see if it can be charged. If it is charged, it proves to be the problem. Change the cable or change the charging plug. Note that when changing the charging plug, pay attention to the same parameters as the current and voltage of the original charging plug of your mobile phone to prevent harm to the mobile phone. If you ca n’t rush, the possible problems are: phone interface problems, battery problems, system problems.

3. First, the mobile phone is connected to the charger and plugged into the plug-in board to see if it can be charged. If it cannot be charged, then the current possible problems are: the charger is broken, the connection cable is broken, the mobile phone interface is broken, the battery is broken, and the system is defective.

4. Remove the battery (do n’t remove it if you ca n’t remove it), use a universal charger to charge, if it is the problem of the charging interface of the mobile phone, if not, continue to investigate, there may be problems: battery, system.
5. Try another battery to see if it can be washed in. If you can charge it after changing the battery, it is likely that this battery is scrapped. Just change the battery. If it still fails to charge, then this can only be a system problem. Note that the battery is best to be an original one or to buy a good-quality business battery. I have broken my phone because of a poor-quality battery. Everyone must pay attention!
6. Many people do n’t understand how the system will affect charging or not charging. I take the Android system as an example. There is a file in the Android system log that records battery information. If the battery information is incorrect, it will cause the mobile phone to fail to charge .
7. Mobile phone battery problem This step only applies to smartphones that can remove the battery by themselves. You can put the battery on a universal charger. If it fails to charge, it is a battery problem. Note that it is best to choose original or high-quality batteries when replacing batteries.
8. System setting failure The Android system has a log that specifically records the battery information. Once the information is wrong, it is naturally difficult to charge it. It is not recommended that users forcibly brush the machine for this reason, unless users with flashing experience can try it. General users can refer to their mobile phone system and take different methods to solve it.

In the past, our mobile phone had to be connected to a charger when it was out of power. At this time, it was often very difficult to use. So now that our mobile phone is out of power, we can charge the mobile phone through the power bank, and also ensure the normal use of the mobile phone. The emergence of the power bank solves the problem of charging and using our phone. However, when we charge the mobile phone, it is best not to play with the phone, because charging and playing the mobile phone is very dangerous and easy to cause the mobile phone to explode.

The above is what Xiaobian introduces to you how the mobile phone can't be charged. I hope it can help you. If the above methods still cannot be solved, it can only be repaired by a professional maintenance organization.
