Does iPhone 13 Auto-Lock dim screen before locking

Is the below true?


AI Overview


Yes, you are exactly right. When Auto-Lock is enabled, your iPhone 13 is designed to dim its screen first as a brief warning before turning off the display entirely to a black, locked screen to save battery.

Yes, the screen dims for about 10 seconds before turning off (at least in iOS 26.6). If you are trying to test the functionality, do not hold your phone or turn off Raise to Wake in Settings > Display & Brightness.
