How to control the brightness of your iPhone or iPad

Macworld

We’ve come a long way in adjusting the brightness setting on our iPhones to strike a balance between legibility (especially in sunlight) and battery life. Modern iPhones and iPads have bright enough screens to remain clearly viewable in summer while also consuming much less power despite the larger size.

But brightness isn’t everything. iOS/iPadOS generally adjusts the brightness of a device’s display to match its analysis of the lighting conditions you’re currently amid.
