The brightness feature is a much-loved iPhone feature that many of us take for granted. The screen keeps dimming automatically when you’re in bed, or any other dark environment, so that it doesn’t keep you awake with its bright blue light. When you’re outside in daylight and want to read something on your phone, the screen will automatically brighten again. How nice is that? But there are times when things don’t go exactly as we would like them to. Because the automatic brightness feature on iPhones can be a little finicky sometimes, especially if your device is getting old. If your iPhone screen keeps dimming at random intervals, here are 5 reasons why and how you can fix it:

This is a really handy feature because it means your phone will last longer between charges, but it’s not great if you’re trying to use it as a reading light in bed, or in any other situation where you want the screen to stay at a certain brightness level.

If you were turning your device to landscape mode to activate the magnification feature. If you don’t want this to happen or you think it’s way too bright when it does, you can turn it off in your iPhone’s settings (go to Settings > General > Accessibility > Magnification and toggle the Magnification switch off).

iPhone Shakes When the Screen Is On
