Auto-Brightness is a highly user-friendly feature that automatically adjusts the brightness of your device based on the light conditions around you. Because of the Control Center slider, brightness has always been quite easy to adjust.
In iOS 10 and prior, you would toggle automatic brightness on and off right from the Display & Brightness section of Settings to improve your viewing experience. Now in the latest version of iOS 11, that option has disappeared. The actual thing is that it hasn’t gone but just moved to another place. So, where has it moved? In iOS 11, Apple has moved this feature to the “Accessibility section.”
iOS devices use an ambient light sensor to adjust brightness levels. The sensor lowers brightness in dark locations and raises brightness in light locations.
Auto brightness in iOS 11 is turned on by default. And you can still change the brightness level from the slider in the new Control Center. But once the environment changes, the auto brightness feature will jump in and override your manual brightness level.
Apple is strongly discouraging users from disabling auto brightness feature. Other than being placing it in Accessibility section, where pretty much no-one will find, it actually has a warning – “Turning off auto-brightness may affect battery life”.
However, sometimes, it’s possible that auto brightness feature on your iPhone or iPad isn’t working out well. Or maybe, you like to control the brightness level yourself. In that case, we can turn the feature off.
How to Turn On/Off Auto Brightness Feature
Step 1: Launch Settings and go to General.
Step 2: Tap on Accessibility.
Step 3: Tap on Display Accommodations.
Step 4: Now, turn off the switch next to Auto-Brightness.
It is also a good idea to keep your brightness on low to extend the battery life of your device. To maximize battery life, let auto-brightness adjust your device’s display, or dim your screen.
