Does Your iPhone’s Screen Keep Dimming? [How To Fix]

iPhone’s Screen Keep Dimming

Many iPhone users have reported that the iPhone’s screen keep dimming. Actually, iPhones have an in-built feature of adapting different lighting conditions around the user, rather than around the phone. iPhones come with an ambient light sensor that automatically adjusts the display brightness if the ‘auto-brightness option is enabled. This is usually a default feature of the iPhones. Also, the iPhone’s screen is designed to get dimmed under certain circumstances. One of them is if the device gets too warm.

Anyhow, some iPhone users have allegedly reported that their iPhone screen gets dimmed automatically for no reason. And it stays like this for several minutes.

Methods You Can Use If Your iPhone’s Screen Keep Dimming

In this article, we will suggest what you can do if the brightness feature is not working as it should be.

Method 1: Turn off automatic dimming

If your iPhone’s screen keeps dimming and you don’t want it, you can just turn off the auto-brightness option and the True Tone option.

  • Go to Settings > Accessibility > Displays & Text Size > Toggle Off the Auto-brightness option.
Toggle On Auto Brightness

To turn off the True Tone settings, follow the steps below

  • Go to Settings > Display & Brightness > Toggle Off the True Tone option.

Anyhow, if you think that the Auto-brightness option is not working properly and you don’t want to turn off the settings either, you may try resetting the Auto-brightness option. In this case, you need to turn the Auto-brightness option off, then restart your device once and turn it on again.

Method 2: Attention Aware Features

This is a feature supported on iPhone X and the above models. If this feature is turned on; it will not dim the display brightness as long as you’re looking at the screen. But if you see the brightness dim while you’re looking at the screen, maybe this feature is not turned on.

To enable this feature on your iPhone, follow these steps: Settings > Face ID & Passcode > Attention Aware Features.

Method 3: Clear the ambient light sensor

Another reason why your iPhone’s screen keep dimming might be an uncleaned ambient light sensor of your iPhone. Sometimes it might happen that dust, dirt, water, etc. covered the sensor and not letting it detect the surrounding lightings.

Now, again go to the Settings > Display & Brightness. Carefully observe the brightness slider in the brightness section of the menu. Try moving to a darker and a brighter room alternatively. This should lead the slider to move from its place and the brightness should go up and down.

If you find the slider moving, then your ambient light sensor is fine and working perfectly. But if it doesn’t, it means your device has a hardware issue and you might need to go for the service of your iPhone.
