Fortunately, there are ways to stop your iPhone from automatically adjusting its brightness.
In this blog post, we’ll show you several methods to stop your iPhone from automatically adjusting brightness, including the pros and cons of each method. We’ll also provide some recommendations for what to do if your iPhone’s screen continues to adjust its brightness on its own.

What’s Needed
To stop your iPhone from automatically adjusting its brightness, you’ll need to have an iPhone running iOS 11 or later. You’ll also need to have access to the Settings app on your iPhone.
What Requires Your Focus?
While the methods for stopping your iPhone from automatically adjusting brightness are straightforward, there are a few things to keep in mind.

Different Methods to Stop iPhone from Automatically Adjusting Brightness
Method 1: Disable Auto-Brightness in Settings
One of the easiest ways to stop your iPhone from automatically adjusting its brightness is to disable the Auto-Brightness setting in the Settings app. Here’s how:
- Open the Settings app on your iPhone.
- Tap "General."
- Tap "Accessibility."
- Scroll down and tap "Display & Text Size."
- Turn off the "Auto-Brightness" toggle switch.
Pros: This method is quick and easy to do. Disabling Auto-Brightness can also help extend your iPhone’s battery life since it won’t be adjusting the screen brightness as frequently.
Cons: Disabling Auto-Brightness means you’ll need to adjust your iPhone’s brightness manually as needed, which can be inconvenient if you’re moving between different lighting environments frequently.
Method 2: Turn Off True Tone Display
Another way to stop your iPhone from automatically adjusting its brightness is to turn off the True Tone Display feature, which adjusts the color temperature of your iPhone’s screen based on the ambient light around you. Here’s how:
- Open the Settings app on your iPhone.
- Tap "Display & Brightness."
- Turn off the "True Tone" toggle switch.
Pros: Turning off True Tone Display can also help extend your iPhone’s battery life since it won’t be adjusting the color temperature of the screen as frequently.
Cons: Disabling True Tone Display means you’ll lose some of the benefits of the feature, such as more accurate color representation and reduced eyestrain in certain lighting environments.
Method 3: Turn off Night Shift
Another feature that can cause the screen brightness on your iPhone to adjust automatically is Night Shift, which reduces the blue light emitted by your iPhone’s screen at night. While this can be helpful in reducing eyestrain and promoting better sleep, it can also interfere with your ability to adjust your iPhone’s brightness manually. Here’s how to turn off Night Shift:
- Open the Settings app on your iPhone.
- Tap "Display & Brightness."
- Tap "Night Shift."
- Turn off the "Scheduled" toggle switch.
Pros: Turning off Night Shift will allow you to adjust your iPhone’s brightness manually without interference from the feature.
Cons: Turning off Night Shift means you’ll lose some of the benefits of the feature, such as reduced eyestrain and better sleep quality.
Method 4: Adjust Brightness Manually
If all else fails, you can always adjust your iPhone’s brightness manually instead of relying on the automatic adjustment feature. Here’s how to adjust your iPhone’s brightness:
- Swipe up from the bottom of your iPhone’s screen to open Control Center.
- Drag the brightness slider up or down to adjust the screen brightness to your liking.
Pros: Manual adjustment gives you complete control over your iPhone’s screen brightness, so you can adjust it to your liking in any lighting environment.
Cons: Adjusting your iPhone’s brightness manually can be inconvenient if you’re moving between different lighting environments frequently, and it can also drain your iPhone’s battery more quickly if you have the brightness set too high.
Why Can’t I Stop My iPhone from Automatically Adjusting Brightness?
If you’ve tried the methods above but your iPhone’s screen brightness is still adjusting on its own, there are a few potential reasons why this might be happening:
1. iOS Glitch
Occasionally, iOS updates or other software changes can cause glitches that affect the way your iPhone’s brightness adjusts. To fix this, try performing a hard reset by pressing and holding the Sleep/Wake button and the Home button at the same time until the Apple logo appears on your screen.
2. Ambient Light Sensor Malfunctioning
The ambient light sensor on your iPhone is responsible for adjusting the screen brightness based on the light around you. If this sensor is malfunctioning, it may cause your iPhone’s brightness to adjust on its own. To fix this, you may need to contact Apple support for further assistance.
3. Display Issues
If your iPhone’s screen is damaged or has other issues, it may affect the way the brightness adjusts. To fix this, you may need to contact Apple support for further assistance.
Recommendations:
