The sleep assist mode of Apple's mobile phone refers to a mode in which the mobile phone is in standby state, which can be set through the power saving mode in the menu of the mobile phone security center.
This mode can save electricity and prolong the service life of the mobile phone. When the sleep mode is turned on, the screen of the mobile phone will be black when not in use, so that the mobile phone keeps low power consumption and the standby time is prolonged.
