While it’s very easy to lock the screen on your iPhone by pressing the Power button on the side of the device, it’s also very easy to forget to do it when you’re done using the phone. Fortunately your iPhone has a setting called auto-lock that will automatically lock the screen when you haven’t interacted with it for a period of time.
Typically the iPhone screen will auto lock after a few seconds or a couple of minutes, but it’s possible that the auto lock feature can be turned off entirely. Our tutorial below will show you where to find the auto lock setting on your iPhone 5 so that you can make it happen more quickly, or turn it off completely.
