Why Does My iPhone Keep Dimming With Auto-Brightness Off?

The auto-brightness features on your iPhone are designed in such a way that they automatically change the brightness of your device based on your surroundings. But why does my iPhone keep dimming with auto-brightness off? This question is asked by many users on the internet.

Even with the auto-brightness feature off, many users are still seeing their screen dimming based on their surroundings. There can be many reasons behind the issue. Features like these are meant for comfort and not for annoyance. A constantly dimming screen, even with auto-brightness off, can be frustrating. If you are facing the same issue, you are in the right place.

In this article, we’ll discuss why your iPhone keeps dimming even with auto-brightness off and how to fix this.

Why does your iPhone keep dimming with auto-brightness off?

The problem of the iPhone screen dimming even with auto-brightness off is very common. Not a lot of people know the reason behind this issue. Here are some of the common reasons behind this issue:

  • Overheating: There is an in-built feature on the iPhones that prevents the internal components from being damaged. So, in case of overheating, the system automatically dims the screen to lessen the overheating damage.
  • Accessibility Features: There are several accessibility settings on your iPhone, like “True Tone” or “Night Shift,” that can cause your screen to dim. Though these features are meant for accessibility, sometimes they can mess with your brightness.
  • Always-On Display (iPhone 14 Pro/Max): This useful feature displays essential information on the locked screen but dims the rest of the display. If you own an iPhone 14 Pro or Max and prefer to avoid this dimming effect, ensure that the Always-On Display feature is turned off.
  • Software Glitches: Sometimes there are software glitches that may cause the dimming issue. If you have recently updated your device to a newer iOS version and have been facing issues since then, the update may have contained bugs.
  • Hardware Issues: Although uncommon, a faulty display or ambient light sensor could be causing the problem.

How to Stop Your iPhone Screen from Dimming?

Now that we know some of the main reasons why your iPhone screen may be dimming, let’s move on to the solution part. Keep in mind that you have to perform every method below. This is because the actual reason behind your screen dimming is not known, and we don’t know which method may work for you.

1. Check Auto-Brightness feature

Sometimes we think that we have disabled the auto-brightness feature, but it is enabled. Even if you have recently disabled the feature, it’s better to cross-check. Here’s how you can disable the auto-brightness feature on your iPhone:

  • Open the “Settings” app on your iPhone.
  • In settings, tap on “Accessibility.”
  • Then tap on “Display & Text Size.”
  • Scroll down to the bottom of the screen and check the auto-brightness feature. If it is enabled, disable it.

2. Disable Night Shift

The Night Shift is an in-built feature of the iPhone that automatically dims the brightness of your screen to minimize strain on your eyes. It is particularly used at night. Here’s how to disable it.

  • Open the Settings app on your iPhone.
  • In settings, tap on “Display & Brightness.
  • Tap on Night Shift.
  • Disable the “Scheduled” option by sliding the bar to grey. Check if the issue is resolved.

3. Turn off true tone

If you have an iPhone SE (2nd generation) and later, there’s a true tone feature on your device. The true tone feature adjusts the color temperature and brightness of your devices according to your surroundings. Though it is a beneficial feature, it may be the reason behind your iPhone screen dimming. Here’s how you can disable it:

  • Open the Settings app on your iPhone.
  • In settings, tap on “Display & Brightness.
  • You’ll find the feature “True Tone.” If the feature is enabled, disable it by sliding the bar to grey. Check if the issue is resolved.

4. Disable low power mode

Low Power Mode is specifically designed to minimize iPhone battery consumption. When enabled, this mode decreases various activities, including screen brightness. If the screen of your iPhone is constantly dimming despite having auto-brightness turned off, check if Low Power Mode is enabled. Here’s how to disable it:

  • Open “Settings” on your iPhone.
  • Tap on Battery.
  • Check if the “Low Power Mode” is disabled. If it is enabled, disable it by sliding the bar to grey.

5. Wait for the iPhone to cool down

If you find your iPhone screen dimming on a bright, sunny day despite having Auto-Brightness turned off, it’s likely the device is beginning to overheat. Even with the auto-brightness feature disabled, iPhones automatically adjust brightness levels as a safety measure when they detect excessive heat. However, the screen will automatically brighten up once the phone has cooled down.

If that’s the case, there’s nothing you can do, as you can’t change this feature. It’s just a safety measure incorporated by Apple into every iPhone. However, you can prevent your iPhone screen from dimming or being overheated by avoiding using heavy apps in sunlight. If you think it is about to overheat, relocate the iPhone to a cool environment.

6. Update your iOS

Apple regularly releases updates to fix bugs and glitches. If you haven’t updated your iOS for a long time, issues like these may occur. So, it is highly recommended to regularly update your iOS to the latest version. Here’s how you can check for pending updates:

  • Open Settings on your iPhone.
  • Tap on General.
  • In the list of settings, tap on “Software Update.”
  • All the pending updates will appear on your screen. Update to the latest version and check if the issue is resolved.

Conclusion

That’s how you can fix the issue of screen dimming even after auto-brightness is turned off. There are high chance that, by performing the above methods, you will solve the issue. However, if you are still facing the issue, there are chances that there’s a hardware issue on your device. If that’s the case, take your iPhone to the nearest service center to seek professional help.
