Dark Mode is designed to be easier on the eyes by providing less harsh display brightness in situations where ambient lighting is lower, while maintaining contrast and vibrancy.
If you have an OLED iPhone, such as an iPhone X, iPhone XS, or iPhone XS Max, enabling Dark Mode may also conserve battery life whenever true blacks are on screen, since black pixels in an OLED panel basically switch off and consume far less power.
Enabling Dark Mode in iOS 13 is easy – simply follow the steps below.
- Launch the Settings app on your iPhone or iPad.
- Tap Display & Brightness.
- Under Appearance, tap Dark to switch to Dark Mode.
Alternately, you can set a custom schedule for the display change by using the Options menu that appears when you toggle on the Automatic switch.
