Causes:
1. Fast charging is normal for phones that support fast charging.
2. Low battery or long idle time of the phone.
3. Aging battery, low capacity.
Solutions:
1. The charging speed of the phone is related to the protocol supported by the adapter and the charging power. If the phone supports fast charging, it is normal for the phone to be fully charged in about 20 minutes.
2. If your phone is in low battery or after a long period of idle, it may carry out an automatic calibration of the power level. The battery displayed will change in a certain range, and after a few times of charging and discharging, it can return to normal.
3. This occurs as the battery ages and its capacity becomes smaller. For a better experience, it is recommended that you replace the battery at your nearest service center.
If none of the above methods solve your problem, please back up your phone data and bring your purchase certificate to the nearest realme customer service center for testing and processing.
