Adjust brightness in Control Center
You can quickly adjust brightness in Control Center:
- On an iPhone X and later, or iPad with iOS 12, swipe down from the top-right corner of your display. On an iPhone 8 or earlier, or on an iPod touch, swipe up from the bottom edge of your display.

Adjust brightness in Settings
- Go to Settings > Display & Brightness.
- Drag the slider to the right or left to adjust the brightness.
From here, you can turn on True Tone*, which uses advanced multichannel sensors to adjust the color and intensity of your display to match the ambient light, so that images appear more natural.
You can also turn on Night Shift, which automatically adjusts the colors of your display to the warmer end of the spectrum—making the display easier on your eyes.
Some display accessibility settings, including Invert Colors, Grayscale, and Increase Contrast, might turn off True Tone.
About brightness levels
iOS devices use an ambient light sensor to adjust brightness levels based on the light conditions around you. The sensor lowers brightness in dark locations and raises brightness in light locations. The auto-brightness feature is on by default.
When auto-brightness is on, you'll notice that your device's brightness slider moves according to changing light conditions.
In iOS 11 and later, you can turn auto-brightness on or off in Settings > General > Accessibility > Display Accommodations.
iPod touch doesn't support the auto-brightness feature.
* You can use True Tone with these devices: iPhone 8 and later, iPad Pro 12.9-inch (3rd generation), iPad Pro 11-inch, iPad Pro 12.9-inch (2nd generation), iPad Pro 10.5-inch, and iPad Pro (9.7-inch).
