One of iOS 13’s most highly anticipated changes is also one of its simplest. The latest version of Apple’s mobile operating system finally introduces a Dark Mode for your iPhone and iPad’s interface, much as last year’s macOS Mojave finally bought a Dark Mode to Apple’s desktop operating system.
Once it’s on, formerly white interface elements of iOS change to black (or a deep slate gray), and the text shifts to a brighter color for better legibility. That means that many Apple apps (such as Mail and Music) will now put less of a strain on your eyes at night, and there’s a small chance that Dark Mode will even improve your battery life. And, of course, it just looks cool.
