What's wrong with the wisdom of mobile phones?

Huawei's mobile phone system version is above EMUI 10. 1, and it will automatically turn on when the battery power of the mobile phone is lower than 15%.

Intelligent refueling is a function of Huawei's mobile phone. When the version of Huawei's mobile phone system is above EMUI 10. 1 and the battery power of the mobile phone is below 15%, it will be automatically turned on. The function of intelligent refueling is to extend the battery life of mobile phones by optimizing the operation of system resources and applications. When the battery of the mobile phone is low, intelligent refueling will automatically shut down some unnecessary background applications and system functions to reduce battery consumption. This can help extend the use time of the mobile phone and continue to use the mobile phone when the power is insufficient.
