Part 3. Troubleshooting: Can't Change Screen Timeout?

Many users encounter issues where their iPhone screen timeout is not working properly, either the screen stays on indefinitely, or turns off too soon, or they can't change the screen timeout on iPhone. Following the solutions below, you can fix these issues and ensure your device functions properly.

Step 2. Toggle off Low Power Mode.

Solution 2. Remove Management Profiles

When you are about to change the screen timeout on iPhone, only to find that the option is greyed out and you can't change the screen timeout, the most possible reason is that your iPhone is under management. If there is a management profile installed on your iPhone, you may be restricted from changing settings like screen timeout. To adjust the screen timeout successfully on an iPhone, you can remove the management profiles first. Here, MagFone iPhone Unlocker comes to the rescue.
