It's okay if the phone's not fully charged
< br >
This is a self-protection function of the mobile phone battery, if it is found that the charge is more than 90%, the more charging is found to be less, it is normal, this phenomenon is called trickle charging, that is, the small current continues to charge until it is full. Today's phones charge the same way. As the name suggests, although it is fast charging, it is charged to 9%, for safety reasons, and it will also be charged slowly.
