How to control the brightness of your iPhone or iPad

iPhone and iPad brightness: Fine-tuning your display for optimal viewing and battery life

We've made significant strides in optimizing iPhone and iPad screen brightness, balancing readability (especially outdoors) with battery efficiency. Modern devices boast bright displays for excellent visibility, even in bright sunlight, while consuming less power than previous generations, despite larger screen sizes.

However, brightness isn't the whole story. iOS/iPadOS automatically adjusts screen brightness based on ambient lighting. This isn't always ideal. You can disable automatic adjustments and use manual controls for consistent brightness.

Manual Brightness Control

Even with automatic brightness enabled, you can override it. Simply access Control Center and adjust the brightness slider. This change remains until the device locks (adjust Auto-Lock time in Settings > Display & Brightness) or you press the power button. The brightness slider is also accessible directly in Settings > Display & Brightness.

For iPhones and iPads with True Tone, the Display & Brightness settings include a True Tone toggle. True Tone uses sensors to adjust color and intensity based on ambient light, ensuring consistent visual appearance across different lighting conditions. Disable this feature if you find it distracting. (True Tone is available on iPhone 8 and later, iPhone SE (2nd generation) and later, and many iPad models.)

Disabling Automatic Brightness

If you prefer a fixed brightness level, disable automatic brightness adjustment. Navigate to Settings > Accessibility > Display & Text Size and toggle off Auto-Brightness.

Note that Apple uses Auto-Brightness for battery management. Disabling it may lead to increased battery drain. Monitor your battery usage in Settings > Battery to track consumption.
