Screen Auto Lock is grayed out on iPhone

iPad auto-lock will be fixed at two minutes if you have enabled Low Power mode:

Settings > Battery > Low Power Mode - set to OFF

If the problem persists after disabling Low Power Mode, perform a forced-restart of your iPad:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

You might also check that Date & Time and TimeZone are also correctly set for your iPad - as these settings are known to cause various functional issues if incorrectly configured:

Settings > General > Date & Time

Have you recently added a professional email account, especially a Microsoft Exchange account, to your iPad? Doing so will prevent some security-related settings to be changed.

Hi Tod,

Thanks for letting us know. This will certainly help other users. I upvoted your reply so that it appears at the top of the thread. It’s been a few months now that the “Solved” button is no longer available so upvoting is the only way to bring useful answers to the top.

Excellent 2024 to you as well!
