Hello, several problems and solutions for automatic shutdown:

You can improve the contact between the two by adding a "pad", which is simply to squeeze the battery tightly and don't let it shake casually.

2. There is a virtual welding phenomenon in the nickel strip inside the battery or the link between the protection plate and the battery cell, which will also lead to unstable power supply and automatic shutdown. It is recommended to replace the battery in this matter.

3. If the motherboard fails, there is usually a problem with the CPU, memory or PM (power management), resulting in unstable power supply, and it needs to be repaired. Most people don't know, according to the mobile phone three guarantees law, mobile phone products are repaired within 1 year, so that if the car manufacturer refuses, you can call 12315 to complain or report to the Consumer Association.
