While most people will opt to keep their smartphone turned on all the time, there are many of reasons you'd want to turn off your iPhone, however it's not immediately apparent how (save for just letting it run out of charge).
Maybe you want to have a digital detox and remove the temptation of a quick Instagram scroll. Maybe you're going into a movie theater where your phone should be off. Or maybe you want to restart the device to install new software or get rid of an annoying glitch.
