The automatic shutdown of the mobile phone is usually caused by the reason of the mobile phone battery.
1. low temperature
Smart phones are all lithium batteries or lithium polymer batteries. Although compared with nickel batteries, lithium batteries have the characteristics of high temperature resistance and low temperature resistance, but its best working temperature is 20±5℃ (non-limited use temperature). when the ambient temperature of the mobile phone is higher or lower than this temperature, the power stored in the mobile phone will drop sharply, especially in the low temperature state, the mobile phone will automatically shut down.
2.The battery connection is loose
The port connecting the internal battery to the motherboard is loose, and there is a virtual connection. In the virtual connection state, the user frequently shakes the mobile phone or uses the mobile phone, which will cause the current output by the battery to fluctuate, resulting in an automatic relationship between the mobile phone.
3. Fault
When some software is installed or an incompatible system version is upgraded, the phone will automatically restart due to incompatibility between the software and the system or between the system and the phone's hardware.
