Change the brightness setting in iOS

You can adjust your screen brightness on iPhone, iPad, and iPod touch.

Set brightness or use Auto-Brightness

  • To change your screen brightness, tap Settings > Display & Brightness and drag the slider to the right or left.
  • If your iOS device has an ambient light sensor, you’ll see an Auto-Brightness setting under the slider. Auto-Brightness uses your device’s light sensor to pick the right screen brightness based on your surroundings.

Under Brightness and Display in the Settings menu, use the slider to adjust brightness.

To personalize Auto-Brightness:

  1. Tap Settings > Display & Brightness and turn on Auto-Brightness. You might notice that the brightness slider moves according to the current lighting conditions.
  2. Adjust the slider to set the Auto-Brightness yourself—and Auto-Brightness will pick future brightness settings based on that.

 

If Auto-Brightness isn’t working as expected, you can reset it. Just tap Settings > General > Reset > Reset All Settings.
