iOS 11: Turn off auto brightness on iPhone

If you have an iPhone with the iOS 11 operating system, the device uses automatic brightness. Your iPhone then adjusts the display brightness to the ambient light. If you want to save your battery or the automatic brightness bothers you, you can disable it in the settings.

Disable adaptive brightness on iPhone

Like most smartphones, an iPhone with the iOS 11 operating system also uses so-called adaptive brightness. This automatically adjusts the display brightness to the lighting conditions of the environment. In strong sunshine, your display will then automatically use the brightest setting, while in darkness or dim artificial light, the phone will dim the lighting to avoid blinding the user. This adaptive brightness can have some drawbacks. For example, the smartphone uses more battery with this setting than if you set the screen to a low brightness level by default. Some users also find the automatic change annoying. In the settings of your device, you can turn off the automatic brightness in a few steps.

How to change the settings

1. Start the settings on your iPhone.
2. Tap on "General".
3. Select "Operating aids".
4. Go to "Display adjustment" and tap next to the option on "Off".
5. The slider turns gray. Die automatische Helligkeit wurde deaktiviert.
