After the phone is fully charged, it should not continue charging as it may damage the battery and the phone's circuit. When the phone battery is fully charged, the charger will automatically stop charging the phone, which is also the design of the phone charger. If you continue to charge, the phone battery voltage will continue to rise, which may cause the battery to expand, leak liquid, and even catch fire. In addition, overcharging can shorten the lifespan of mobile phone batteries and affect phone performance.
If you need to use your phone for a long time, it is recommended to charge it when the battery level is below 20% to keep the battery in a healthier state. When the phone is fully charged, the charger should be promptly unplugged to protect the battery and phone circuit. When charging, the original charger should be used, and inferior chargers or charging cables should not be used, as this can cause slow charging speed or overcharging.
