1, non-original charger charging, charging abnormal, please use the original charger.
2, the use of mobile phones when charging, resulting in slow charging or less charging, please do not use the mobile phone when charging, and clean the background program before charging or shutdown charging observation.
3, malware caused by the exception, please uninstall the recently downloaded software to try.
4. If the system is abnormal after the mobile phone is root, you need to remove root and observe. Solution: It is recommended that you try the following operations: 1. Shutdown charging test. 2. Replace the charging position to eliminate intermittent charging problems caused by poor socket contact. 3. If conditions allow to replace the original charger for testing. Or send it to repair for testing. 4. When charging, if the phone is equipped with a third-party plug-in such as charging doctor, it is recommended to uninstall and test. 5.

Now there are two mainstream fast charges:
low voltage high current and high voltage low current
low voltage and high current based on OPPO's vooc flash charge (OnePlus Dash flash charge)
A matching data cable and charging head are indispensable.
High voltage and low current based on Qualcomm QucikCharge
The charging head is more important, and the inferior data cable will have an impact, but it will not affect it very seriously.
In fact, first you need a mobile phone that supports fast charging haha
