iPhone brightness keeps dimming? When your iPhone screen dims randomly, it gets difficult to use the phone and enjoy multimedia content. If you find yourself in a similar situation, I can help you to fix the issue and make your iPhone brighter again.
Why does my iPhone keep dimming?
Your iPhone may dim the screen to save battery. This is a normal phenomenon. But for most users, the main reason for an unusually dimmed iPhone screen is an accessibility feature called Reduce White Point. When this is enabled, the intensity of bright colors is significantly reduced, resulting in a dim iPhone screen.
Other reasons might include auto-brightness not working, a bug in iOS, enabling zoom, a faulty iPhone screen, and more. But before moving on, consider the following basic points which may cause the issue.
1. Are you using a screen protector that dims the display?
Several screen protectors (low quality or matte ones) reduce the brightness. If you are using one, consider removing it or switch to a better screen protector. The same goes for plastic screen lamination/protector.
2. Are you using a non-Apple display?
Did you ever get your broken iPhone display replaced cheaply from an untrusted, non-reputed, or unauthorized service center? If yes, they may have used a low-quality display that is not too bright.
In this situation, you can get a better screen by taking your phone to an Apple-authorized repair shop or at least one that is reputed and has good reviews. Talk to your friends about this or look for a local repair shop with good reviews.
3. Is an app lowering the screen brightness?
Are you using a video, photo, or game app that manually lowers the screen brightness when you are inside it? If yes, take a minute to explore the app’s settings and make sure to turn off any screen brightness or customization options.

7 Ways to stop iPhone dims automatically
- Increase the brightness and turn off auto-brightness
- Turn off Reduce White Point on iPhone
- Disable screen zoom
- Turn off Dark Mode, True Tone, and Night Shift
- Restart your iPhone
- Make sure your iPhone is not too hot
- Reset all settings
1. Increase the brightness and turn off auto-brightness
The first step (which you surely know) is to increase the iPhone screen brightness manually. You can do this from the Control Center or Settings.
To increase brightness via Control Center:
- On iPhone with Face ID, swipe down from the top right corner (where the battery icon is).
- On iPhone with Home button, swipe up from the bottom of the screen.
- Drag the brightness slider (with a sun icon) up.
To increase brightness via Settings:
- Open Settings and tap Display & Brightness.
- Drag the BRIGHTNESS slider to the right.
Auto-brightness won’t work correctly if the top portion of your iPhone is extremely dirty or covered using a front case. This will prevent the ambient light sensor from functioning and adjusting your screen brightness correctly. To address this, clean your iPhone or remove the weird front case.
Alternatively: You may also turn off auto-brightness which will keep the screen brightness you set manually. This will prevent changing the brightness in different lightings automatically. Thus, you will have to adjust the iPhone brightness manually from the Control Center or Settings app.
If your iPhone brightness keeps dimming even with auto-brightness off, move on to the following way.
2. Turn off Reduce White Point on iPhone
This is one of the main reasons why your iPhone screen brightness is low. You may have enabled it intentionally (and forgot) or someday while exploring the options.
Here’s how to turn off Reduce White Point to fix the dim iPhone screen issue.
- Open iPhone Settings and tap Accessibility.
- Tap Display & Text Size.
- Toggle off Reduce White Point.
3. Disable screen zoom
If you have enabled screen zoom, this may be the reason for a dimmer screen. To fix this, tap Accessibility inside iPhone Settings. Next, tap Zoom and turn it off.
4. Turn off Dark Mode, True Tone, and Night Shift
Dark Mode: The iPhone screen has a black background, and the text is shown in white. If you have an iPhone with an OLED screen (iPhone X, XS, XS Max, 11 Pro, 11 Pro Max, and any model from 12 series), dark mode saves battery.
True Tone: This automatically adapts the iPhone 8 and later model’s display according to the ambient lighting conditions. True Tone ensures that there’s color consistency in all environments.
Night Shift: This filters out blue light and shifts the screen to a warmer orangish tint. Apple claims that this may help you get a better night’s sleep.
Turning off these display preferences may help make the screen more pleasing and comforting to you. I do not use Dark Mode, True Tone, or Night Shift. I like normal mode. If you also have similar preferences, follow the steps below to turn these off and see if you like the screen better now.
- Open iPhone Settings and tap Display & Brightness.
- To turn off Dark Mode, choose Light under APPEARANCE.
- Toggle off True Tone.
- Tap Night Shift and toggle off all the green switches.
You can also enable and disable all these three options from the Control Center. For this, press the brightness slider, and you will see the icons at the bottom.
Tip: If your iPhone screen dims after 30 seconds, tap Auto-Lock inside Display & Brightness settings. Next, choose any option other than 30 seconds. However, if you enable Low Power Mode, the phone display will automatically dim and lock after 30 seconds.
5. Restart your iPhone
At times, the most complex issues can be successfully solved by a simple restart. Before looking at the other solutions, go ahead and turn off your iPhone. After a minute, turn it back on.
6. Make sure your iPhone is not too hot
Is your iPhone too hot? If yes, although rarely, it may alter the screen appearance. Make sure you close unnecessary apps and remove the case. Let the iPhone cool down. Turning it off for some time will also help a lot.
7. Reset all settings
At last, if nothing helps, try resetting all settings. This will delete all the settings you have customized. Everything will go back to the default state. However, this won’t affect your personal data like applications, photos, videos, music, and more.
- In Settings, tap General.
- From the bottom, tap Reset.
- Tap Reset All Settings and proceed.
- After it completes, see if the dim screen issue is solved or not.
