iOS’ built-in Auto-Lock feature is great for saving battery life by killing the backlight on your screen, but there are times when it can be less than ideal. Luckily, there’s an easy way to take control of the feature—or turn it off altogether. Open up the Settings app, tap on General, tap on Auto-Lock, and set it to the time limit you’re comfortable with. Just remember if you turn it off completely that you’ll need to manually lock your phone every time you’re done with it—or face a battery that’s out of juice way before its time.
