How to change the screen lock time on your iPhone

You have probably noticed that the iPhone screen turns off automatically after a period of inactivity. When this happens, the iPhone will also be locked and you will need to enter your passcode or use Face ID or Touch ID to unlock it. The amount of idle time before this happens is your iPhone’s screen lock time setting.

Follow these steps to change your iPhone screen lock time. These instructions apply to all iPhones with recent versions of iOS.

  2. Tap Display and brightness.

  3. To elect auto lock.

  4. Select the amount of idle time you want before the iPhone screen locks. A shorter time is probably better (as discussed in the next section). You should probably avoid choosing Never unless you really understand the risks and benefits.

Why do I need to change the screen lock time on my iPhone?

There are three main reasons to change the screen lock time setting on your iPhone:

  • Easy to use: It can be annoying to lock your iPhone’s screen too quickly and have to unlock it several times a day when you want to use it. If your unlock tolerance is low, it may be best for you to extend the screen lock time.
  • Battery: Battery power is required to keep the iPhone’s screen lit. As a result, the longer you wait for your screen to automatically lock, the more battery life you’ll use. By keeping the screen lock time low, the battery may last longer before it needs to be recharged. (Screen lock settings are just one of our many tips for extending iPhone battery life.)
  • Safety: Security is perhaps the most important reason to check your screen lock time. The longer your iPhone is unlocked, the more likely someone will gain unauthorized access to your personal information (texts, photos, banking and health information) stored on it. A faster screen lock time improves iPhone security because it shortens the period of time your data can be accessed without entering your passcode.
