Turn it off and charge.
Try turning it off and charging it, and see if it can solve the problem. This can prevent the mobile phone from running applications while charging, thus improving the charging efficiency.
Replace the charging port
Change the charging port. Is it the socket? Sometimes the poor contact of the socket will lead to a slow charging speed or even no charging.
Spare charger or send for repair inspection.
Spare charger or send for repair inspection is a good choice. If there is something wrong with the charger itself, even changing the charging port will not help. If there is something wrong with the mobile phone itself, it needs to be repaired.
Uninstall the charging doctor plug-in
Is there a charging doctor plug-in in the mobile phone? Try to uninstall it. Some charging doctor plug-ins will occupy a lot of system resources and affect the charging efficiency.
Check the charging interface
Check the charging interface and don't let foreign objects make trouble! Sometimes foreign objects such as dust and hair will enter the charging interface, which will affect the charging efficiency.
Back up important data
Backing up important data and restoring factory settings may help you. If none of the above methods can solve the problem, then restoring the factory settings may be the last choice. But before restoring the factory settings, be sure to back up important data.
