Why can’t I change auto look on my iPhone

If you’re unable to change the auto-lock settings on your iPhone, there are a few possible reasons:

  • Restrictions:

Check if you have enabled any restrictions or parental controls on your device. Restrictions can limit certain settings, including auto-lock options. To adjust the restrictions, go to Settings > Screen Time > Content & Privacy Restrictions.

  • Software version:

Make sure your iPhone is running the latest version of iOS. Apple periodically releases updates that address various issues and bugs, including any related to auto-lock settings. To check for new updates just go to your phone Settings > General > Software Update.

  • Battery settings:

If your device’s battery level is critically low, some iPhone models may automatically enable the “Low Power Mode,” which overrides the auto-lock settings. Connect your iPhone to a power source and check if the auto-lock settings become editable.
