If you find that your iPhone 11’s auto brightness feature is making your screen too dim or too bright for your preference, turning it off gives you full manual control over your display brightness. This can be especially useful if you’re trying to conserve battery, work in specific lighting conditions, or simply prefer a consistent screen brightness. Before you begin, ensure your iPhone 11 is updated to the latest version of iOS for optimal performance and access to the latest settings options.
What You’ll Need
- An iPhone 11 with iOS updated to the latest version
Step-by-Step
- Unlock your iPhone 11 and go to the Home screen.
- Open the Settings app by tapping on the gear icon.
- Scroll down and tap on “Accessibility.”
- Within Accessibility, find and select “Display & Text Size.”
- Scroll down to locate the “Auto-Brightness” option. It is usually towards the bottom of the page.
- Toggle the switch next to “Auto-Brightness” to the OFF position. When disabled, the switch will no longer be green.
- Exit Settings. Your screen brightness is now manually controlled.
- Adjust your brightness manually by opening the Control Center: swipe down from the top-right corner of the screen. Drag the brightness slider up or down to your preferred level.
Common Mistakes
- Not scrolling to “Display & Text Size” in Accessibility — auto brightness is located here, not directly in the main Settings menu.
- Forgetting to toggle the switch off — leaving it on will keep auto brightness active.
- Attempting to turn off auto brightness in the wrong settings section, such as in Display & Brightness instead of Accessibility.
- Not updating iOS — sometimes, features or settings locations change with updates, so ensure your device is current.
- Confusing auto brightness with other display settings like True Tone, which is a separate feature.
Tips
- If you want to revert to auto brightness later, follow the same steps and toggle the switch back on.
- Adjust brightness in the Control Center for quick changes without diving into Settings.
- Use auto brightness if you want your screen to adapt automatically to changing lighting conditions, saving battery and reducing eye strain.
- Remember that manual brightness settings may drain the battery faster in certain lighting conditions.
Troubleshooting
If you’ve turned off auto brightness but notice your screen still adjusts unexpectedly, try the following:
- Restart your iPhone 11 to refresh system settings.
- Ensure that “True Tone” is turned off if you want absolute manual control over brightness, as it can affect display appearance.
- Check for iOS updates by navigating to Settings > General > Software Update. Installing the latest updates can fix bugs related to display settings.
- If the brightness slider is unresponsive, try resetting all settings by going to Settings > General > Reset > Reset All Settings. Note this resets personalized settings but not your data.
Frequently Asked Questions

Go back to Settings > Accessibility > Display & Text Size, then toggle the “Auto-Brightness” switch back on.
