Check the charging interface
It is very likely that the charging interface located at the bottom of the mobile phone enters dust, resulting in poor contact between the interface and the data cable plug. So when the phone can't be charged, you can first check whether the interface at the bottom of the phone is blocked by foreign objects.
Replace the charger and power cord.
If there is nothing wrong with the power interface of the mobile phone, then we can use the replacement method to replace the charger and power cord we usually use. If you have a computer at this time, you can connect one end of the data cable to the USB port of the computer to see if it can be charged normally. If it can be charged, there is something wrong with the charger.
Replace data cable
If we connect the mobile phone to the computer and can't charge it, we can try to charge it with other data cables at this time to see if it can be solved after changing the cable. If changing the line can solve the problem, it means there is something wrong with the line. Replace the data cable connector.
Restart the phone
You can also try to restart your phone. The mobile phone battery can't be charged, which may be a system problem or a battery temperature problem. If it is the latter, you can try to turn it off and let it stand for a while or put it in the shade before trying to recharge.
Send for repair inspection
If none of the above methods can solve your problem, at this time, you need to recall whether the mobile phone is flooded or dropped. Because water or falling may damage the internal parts of the mobile phone, it can't be charged. Of course, it may also be caused by the aging of the mobile phone battery. If it is a hardware problem of the mobile phone itself, the mobile phone can only be repaired and tested.
