Phone charger does not pull out, it will accelerate aging

Everyone likes to play mobile phones before going to bed. In order to have enough power to go to work the next day, many people plug the phone into the charger and charge it all night. Then, the phone that can be fully charged in two hours can be charged for seven or eight hours. Why is there no explosion?

The mobile phone battery management chip has a function of cutting off the power supply after the power reaches 100% during charging, which is done by adding an overcharge protection circuit. Therefore, although the mobile phone was charged for one night, in fact, after the battery was fully charged, the charger stopped supplying power, which had no effect on the mobile phone. However, the plug that is fully charged will have some impact.

Sometimes the battery of the mobile phone is not broken, but the charger is broken, and it is easy to damage our mobile phone battery when it is charged. If the charger head is also plugged into the power socket when not in use, the charger will be aging and damaged for a long time. Once the problem occurs, it is a short-circuit and other serious consequences that may cause fire.

The mobile phone should not be played while charging. The charging process converts electrical energy into chemical energy. This process will release a lot of heat. If the mobile phone is used at this time, the temperature is too high, which may cause damage to the processor and affect the stability of the voltage. The power management chip not only distributes the battery power like the housekeeper, but also manages the voltage during charging and discharging. The mobile phone continues to be used during charging, which easily affects the judgment of the power management chip.
