Effectively using the touch ID and passcode on your iPhone is one crucial step to ensuring that the important sensitive data on your iPhone is as secure as possible. In most situations, your iPhone screen should automatically lock after a period of inactivity, then the device will require a fingerprint of password before the device can be used again.
But you may find that your screen is not automatically locking as it should which presents a security risk, a potentially needless battery drain, and opens the iPhone up to pocket dialing. If your screen is not turning off, then the first place to look is the Auto Lock setting. If that setting was adjusted to remain on, or if the amount of time that it remains on has been extended, then you can follow our steps below to make your iPhone screen start turning off again.
How to Get Your iPhone 7 Screen to Turn Off When Not in Use
The steps below were performed on an iPhone 7 Plus, in iOS 10.2.
