Operation method
Wiring problem Change a connecting wire or a charging plug, and then charge again to see if the power can be charged. If the power can be charged, it is the problem. Just change a wire or a charging plug. Pay attention to replacing the charging plug with the same current and voltage parameters as the original charging plug of your mobile phone to prevent harm to your mobile phone.
Interface problem Remove the battery (don't forcibly remove the battery if it can't be removed), and use the universal charger to flush it. If it can flush it, it is the problem of the charging interface of the mobile phone.
System problems Many people don't understand how the system affects the inability to charge. I take the Android system as an example. There is a file in the log of the Android system that records the battery information. If the battery information is wrong, the phone will fail to charge.
The output voltage is insufficient. The output voltage and power of the computer charging cannot meet the standard charging voltage and power. As a result, the more you charge, the less you charge. This will also have some impact on the mobile phone hardware.
