If you do not do any operations on your iPhone in a period of 3 minutes or 5 minutes, the screen will be off. That is when we consider that the iPhone is now in sleep mode. But sometimes, we just don't want the iPhone screen to be turned off or frequently enter the passcode or use your finger to unlock the iPhone over and over again. Here we will show you how to change it.
You can change the sleep mode on your iPhone by changing the Auto-Lock period. You can set the period of time that should last before sleep mode is activated or switch off the sleep mode completely.

Step 2. Scroll down and find Display & Brightness.
