Your iPhone’s screen can be difficult to see in very bright environments, which can lead you to dramatically increase the screen brightness. But a maximum brightness screen is often harsh on your eyes in indoor, low-light environments, so you will need to adjust that when you get back inside.
One way to manage this is to use the Auto-Brightness setting on the iPhone. But you may have found that Auto-Brightness is affecting your ability to control your own screen’s brightness, so you might be looking for a way to turn it off. Our guide below will show you where to find and disable the Auto-Brightness option on your iPhone.
How to Disable the Auto Brightness Setting on an iPhone 7
The steps in this article were performed on an iPhone 7 Plus, in iOS 10.3.3. This is going to disable the feature on your iPhone that causes the screen color to update automatically based on the ambient light in your current environment.
Step 1: Open the Settings menu.
Step 2: Select the Display & Brightness option.
Step 3: Tap the button to the right of Auto-Brightness to turn it off. You will know that the setting is turned off when the button is in the left position and there is no green shading around it. I have turned off Auto-Brightness in the picture below.
Keeping your screen brightness as low as possible is one good way to conserve battery life. Another is to use the Low Power Mode on your device whenever possible.
