In fact, the difference between restart and restart is very simple. The switch needs to restart the system, but the restart mode does not. Because turning off and turning on is to re-test the whole hardware and system of the mobile phone, the processor needs to run at full speed during this process, so the whole process will be slow. The restart mode doesn't need so many steps, just shut down the software and restart, which has no effect on the hardware, so it is faster and more power-saving.
