and hold Option + Sym + R, and then release the keys all at once.
Give this method at least 10 seconds for the restart to begin.
Why this might help
A triple-toggle or 3-key restart may be effective if the screen is off and you
can’t turn it on, or if gestures don’t work. These restarts also close all
applications, free memory, and reinitialize wireless services (phone,
Bluetooth
®
technology, Wi-Fi, and VPN).
NOTE Because open applications are forced to close immediately during a
triple-toggle or 3-key restart, some unsaved data may be lost.

due to a low battery.

can be good for your computer. Every once in a while, restart your smartphone.
