Auto-Lock Setting on iPhone Greyed out? How to Fix

Sometimes the auto-lock function on your iPhone might be greyed out and you cannot change the settings because it is stuck on thirty seconds. If this feature is greyed out, it means you cannot make any changes to the settings. The reason for this problem could be that your iPhone is in Low Power Mode which restricts the auto-lock to only 30 seconds. This happens automatically in order to conserve power.

Once you have recharged your device you can disable the Low Power Mode and the auto-lock setting will also be enabled. To enable or disable the Low Power Mode simply go to Settings > Battery > and then toggle the Lower Power Mode switch.
