The overcharging phenomenon of mobile phone chargers refers to the situation where the battery is already fully charged during the phone charging process, but the charger still continues to deliver current to the phone, resulting in overcharging of the battery. Normally, the built-in smart battery management system of a mobile phone will automatically stop charging to avoid overcharging. However, if the charger itself has defects or incompatibilities, or if human factors cause the charger to be turned on for a long time, it may lead to overcharging.
Overcharging can cause serious damage to the battery life. Long term overcharging can lead to accelerated chemical reactions within the battery, thereby accelerating the loss of battery life, gradually reducing battery performance, and ultimately causing the battery to no longer maintain sufficient charge. Moreover, overcharging can increase the internal temperature of the battery, and in severe cases, it may cause safety hazards such as overheating and explosion.
To avoid overcharging of mobile phone chargers, it is recommended to use matching original chargers. Do not use low-quality or inferior chargers, and do not allow the phone to be connected to the charger for a long time to avoid affecting battery life and safety. In addition, you can choose some chargers that support fast charging and have overcharge protection function.
