Turn Off Auto Brightness iPhone feature running on iOS

March 24, 2020

With the introduction of iOS 13, Apple has somewhat hidden the auto-brightness toggle. The option no more appears under the ‘Display & Brightness' section of the phone's settings but that doesn’t mean the feature has been wiped out. Follow this post to know how to turn off the auto brightness iPhone feature, running on iOS 13 or later.

How to turn off auto brightness iPhone option

The auto brightness iPhone setting works as a battery-saving feature. It resides deep inside the ‘Accessibility’ section. In case this hideous relocation is driving you nuts, here’s how to find and disable it on your iOS device.

  1. Go to Settings.
  2. Select the Accessibility option.
  3. Choose the Display & Text Size option.
  4. Set the toggle for the Auto-brightness option to Off position.
  5. Exit Settings.
  6. The option will be disabled permanently.

iOS devices use an ambient light sensor that automatically adjusts brightness levels based on the light conditions around you. It lowers brightness in dark locations and raises it in light locations.


How do I turn off auto-brightness on iPhone?

When auto-brightness is enabled, it will automatically change your iPhone's screen brightness based on how much light is surrounding you. Let's say, if you are in a dimmer room, you'll find the screen brightness going down, and when you move into the brighter room, it'll go up. Although good, some may find it nothing more than a nuisance. Find how to disable it completely!

On your iPhone, go to the ‘Settings’ app and scroll down until you find the ‘Accessibility’ tab.

When the Accessibility page opens, choose ‘Display & Text Size’ in the first section.

Scroll down to locate the ‘Auto-brightness’ option. It should be visible to you at the very bottom of the page.

Simply toggle the slider to the ‘Off’ position. The feature will be instantly disabled.

Hereafter, your iPhone should no longer change the brightness automatically.

You need to disable it since the feature is on by default. In case you would like to enable the feature again to save the battery power, repeat the above steps to ‘Turn On' the toggle. We do not recommend disabling the feature as it dims the screen to extend battery life and automatically adjusts the screen for your lighting conditions.

iPod touch doesn't support this feature.

Hope this helps!
