An electronic butterfly that says goodbye as soon as it is turned off.

The meaning of electronic butterfly is a metaphor, which means that once the electronic equipment is turned off, the data stored in it will fly away like a butterfly and cannot be retrieved. The metaphor of saying goodbye as soon as the electronic butterfly is turned off stems from the difference between deep sleep mode and off state. In deep sleep mode, the device is still running and the data still exists, but in the off state, all the data of the device is cleared. "Power off" means that the mobile phone is completely turned off, that is, the power is cut off and the mobile phone will not do any more operations. When the power off button on the mobile phone is pressed, the mobile phone will stop all running programs and systems, all tasks will be interrupted, and the memory of the mobile phone will be completely emptied. "Restart" refers to the restart of the mobile phone, which will close all running applications, clear all temporary data and restart the mobile phone system.
