What is Auto-Lock on iPhone? Just as its name suggests, it is a feature that controls how long your iPhone screen stays on before it automatically turns off and locks. If you don't use your iPhone for a set period of time, your iPhone screen will automatically turn off and lock to reduce unnecessary power consumption and protect your privacy when you are away from your iPhone.

By default, Auto-Lock is set to 30 seconds, which means your iPhone will automatically turn off and lock the screen after 30 seconds of inactivity.

However, some users may not want the screen to turn off automatically, especially when they are reading long content or following a recipe. Therefore, this post is going to introduce how to turn off Auto-Lock on iPhone.
