How to Change Screen Timeout on iPhone to Save Battery

This guide uses an iPhone 12 with iOS 18.1.1. If you're using an older version, don't worry, the menu locations remain the same as shown in the images.

Steps:

1. Open Settings

   Start by opening the "Settings" app on your iPhone.

2. Display & Brightness

   

   Scroll down and tap on "Display & Brightness." This menu allows you to adjust screen-related settings, including brightness levels and dark mode.
3. Auto-Lock

   

   Scroll down until you see the "Auto-Lock" option. Tap on it to open the automatic screen lock settings. Here, you'll see several time options for auto-locking the screen.
4. Select Auto-Lock Time

   Choose the auto-lock duration that fits your needs.

   • If you frequently transfer large amounts of data between iPhones, select the longest duration, such as 5 minutes, to prevent the screen from turning off in the middle of a transfer.
   • To save the battery, select the shortest duration. Setting it to 30 seconds or 1 minute will reduce battery usage by turning off the screen quickly when not in use.
5. Test the New Auto-Lock Time

   Return to the home screen and test the new auto-lock time to make sure it meets your expectations. Ensure that the screen turns off as expected according to the new setting.
