Hello, several problems and solutions of automatic shutdown:

1. Confirm whether the contact between the battery and the battery connector of the mobile phone is reliable and normal. If it is found loose, there is a hidden danger of automatic shutdown. You can improve the contact between them by adding a "pad". Simply put, squeeze the battery tightly and don't let it shake casually.

2. There is a phenomenon of virtual welding between the nickel belt or the protective plate inside the battery and the battery core, which will also lead to unstable power supply and automatic shutdown. It is recommended to replace the battery.

3, motherboard failure, usually CPU, memory or PM (power management) problems, resulting in unstable power supply, at this time need to be repaired. Most people don't know that mobile phone products are guaranteed to be repaired within 1 year according to the mobile phone three-guarantee law. If the manufacturer refuses, you can call 123 15 to complain or report to the consumer association.

4, software failure, because there is a BUG in the software operation, the internal mechanism automatically determines to restart, so you will find that you often shut down and automatically restart. You can try to upgrade the software version again.

That's basically all ~
