2. Overcurrent: When the mobile phone battery current is too large or the charger output current is too large, the power IC may be affected by overcurrent and burn.
< br >
3. Short circuit: When there is a short circuit in the mobile phone circuit, the power supply IC may be burned by excessive current impact.

Therefore, in order to avoid the burning of the mobile phone power IC, we need to pay attention to factors such as the charger, battery and ambient temperature when using the mobile phone, and choose a reliable quality power IC.
The power IC of Apple 12 is damaged because of the following reasons: 1. The use of time is too long, there may be some oxidation or circuit aging phenomenon, resulting in damage to the power IC.
2. Accidental impact or drop may cause the power IC to be damaged due to excessive force.
3. The use of incompatible or inferior chargers, the voltage is unstable, may lead to power IC overpower and damage.
Due to the damage of the power IC will cause the Apple 12 can not be turned on or charged normally, so it should be repaired or replaced in time.
Hello, the power IC damage of Apple 12 May be caused by the following reasons:
1. Overvoltage: If the device is subjected to too high a voltage, the power supply IC may be damaged.
2. Overheating: Prolonged use or excessive use may cause the device to overheat, which may cause damage to the power IC.
3. Static electricity: If the static electricity is not handled correctly, it may damage devices such as the power supply IC.
4. Bad parts: If the power IC itself has manufacturing defects or bad parts, it may cause it to be damaged.
5. Mechanical damage: If the device is hit or other mechanical damage, the power IC may be damaged.
