On iPad, you can make your screen dimmer or brighter (dimming the screen extends battery life). You can also adjust the screen color and brightness manually or automatically with Dark Mode, True Tone, and Night Shift.
To make your iPad screen dimmer or brighter, do one of the following:
> Accessibility.
Tap Display & Text Size, then turn on Auto-Brightness.
Dark Mode gives the entire iPad experience a dark color scheme that’s perfect for low-light environments. With Dark Mode on, you can use your iPad while, for example, reading in bed, without disturbing the person next to you.
Do any of the following:
> Display & Brightness, then select Dark to turn on Dark Mode or select Light to turn it off.
