How to solve an exception during mobile phone charging

1. Check whether the mobile phone charger is used for charging and whether the charging is normal.
2. If an exception occurs during charging with the standard charger, you can try to connect to the USB port of the computer through the data cable and record the charging. If the charging is normal, the charger header may be abnormal.
3. If the charging is still abnormal when the USB port of the computer is connected through the data cable, it may be caused by oxidation of the metal contacts of the data cable and the metal contacts of the mobile phone. It is recommended to use an eraser or alcohol (for industrial purposes) the battery metal contacts and interfaces are cleaned. It is recommended to compress the data line and the contact port of the mobile phone during charging. Loose or poor contact may lead to charge failure.
4. You can also change the charger or battery of the same standard to charge the instance. If other chargers are normally charged, the charging may be abnormal due to abnormal charger. If the charging is normal after other batteries are changed, the cell phone battery itself may be abnormal.
5. If the power-on period is too long, check whether you are using your mobile phone while charging or whether the backend is running many applications. Because mobile phones work with a large number of hardware-related components and call a large number of processes, in order to ensure a good user experience and fully load the CPU, the power consumption is high, it also consumes a lot of power, so the charging time will be extended. Applications running in the background can be set through the path "system settings"-applications (applications) -Running: shut down unnecessary applications (The following figure uses S890 as an example ).
