What Is Auto Lock On iPhone
The Auto–lock setting on the iPhone is a feature that allows you to set the amount of time before your iPhone automatically locks and turns off the display. This feature is designed for two main purposes:
- Saving battery life when your iPhone is not being used.
- Security by locking itself (You don’t want someone using your iPhone if you forgot to lock it)
You can change the duration time at which the iPhone auto-lock itself or turn off and completely disable it, but you may experience having the Auto lock setting greyed out, find below why and how to fix this problem.
