Why You Should Turn Off S21?

Turning off Samsung Galaxy S21, S21 Ultra, or S21 Plus 5G can help you in various ways in order to improve the workability of the smartphone and improve the performance of the RAM as well as the battery.

Firstly, when you power off your S21 and start it again, all the cached data in RAM is erased. All previously operating app fragments are deleted, and all currently open applications are terminated. RAM is effectively “cleaned” when the phone restarts, so eventually you’re beginning with zero once again.

Consider how many applications are open on your phone, steadily draining memory and battery capacity. Thus, turning off your phone clears any open apps or memory leaks, as well as anything else that is consuming your battery.
