Change the auto-lock on iOS

Changing the auto-lock time in iOS can be a big battery saver, especially if you’ve set the screen to just stay on all the time.

To turn it off after a certain time, head to the Settings app, then to “General”, and then select “auto lock”.

There you’ll be able to select when you want the screen to turn off, ranging from two minutes, to 15 minutes, or never.
