The screen on your iPhone 7 is probably the biggest drain on the device’s battery. The brighter the screen, the more battery life it consumes.
Finding the right balance for that brightness setting is an important aspect of making sure that your phone doesn’t die so quickly.

This setting allows the screen to adjust automatically based on the ambient lighting around the device. That means that the screen will dim or brighten as your environment is darker or lighter.
Our guide below will show you where to locate that Auto Brightness setting so that you can turn it on or off.
