Most software glitches can easily be fixed with a system reboot. If none of the other troubleshooting steps worked in your case, it’s likely that the screen dimming is caused due to a software-related glitch that’s associated with iOS/iPadOS.

Just make sure that all the toggles under the Night Shift section are disabled as shown in the screenshot below and you’re good to go. The Night Shift setting can be accessed from the Display & Brightness settings menu and it’s located right below the True Tone toggle. Due to the increase in warmer tones during nights, you may feel that your iPhone’s display has become slightly dimmer. Night Shift basically just makes your display warmer close to your bedtime and reduces the amount of blue light that causes eye strain. Instead, the feature works according to your time. Night Shift is a feature that’s very similar to True Tone, except that it doesn’t rely on ambient lighting. If you’re sensitive to these changes, you can disable it by going to Settings -> Display & Brightness -> True Tone on your iPhone or iPad. It can make the display appear slightly warmer or cooler depending on the surrounding lighting and give you the perception that the display has dimmed. True Tone is a display feature that allows your iPhone’s screen to adjust the screen based on the ambient lighting conditions so that colors appear consistent across different environments. Turn it off if you find that it’s enabled. Open the Settings app and go to Accessibility -> Display & Text Size and you’ll find the “Auto-Brightness” toggle at the bottom. Instead, you’ll find it in the accessibility section.

Weirdly enough, the auto-brightness feature isn’t located under the display settings.

As mentioned earlier, it’s a feature that’s enabled out of the box, so if you haven’t fiddled with the display settings, this is likely the culprit. The first thing you need to do when you’re facing screen dimming issues is to check if auto-brightness is enabled on your iPhone or iPad. You can follow these troubleshooting steps to first diagnose what’s exactly causing the screen dimming and then turn off some unnecessary features to maintain a certain brightness level. Fix Random iPhone / iPad Screen Dimming Automatically If you’re the kind of person who prefers using a fixed brightness setting or you’re sensitive to screen dimming, read on to take a look at the possible reasons why your iPhone or iPad’s screen is dimming automatically and how you can fix it. These aren’t really issues per se, but just configurations that can be easily changed. Sometimes, other display features that Apple advertises can affect the perceived brightness of your device’s screen. However, this is not the only reason for screen dimming. Both iPhones and iPads are set to automatically adjust the display brightness out of the box, so unless you changed your display settings, this is the reason why you notice that your screen is dimming on its own.
