The low power mode is a power saving mode. When the mobile phone turns on the low power consumption mode, the system will reduce the frequency of using various resources, reduce the screen brightness and shorten the screen display time. At the same time, in this mode, the system will also turn off functions such as WiFi and Bluetooth to achieve the purpose of extending battery life.

In low-power mode, incoming calls and short messages can be received normally, but other online functions are temporarily prohibited. At present, most mobile phones are equipped with the function of turning on the power saving mode when the remaining power of the mobile phone is not much. When the power is lower than a certain value, the system will prompt whether to turn on the power saving mode.
