With Android 10, and iOS 13, you can now apply a systemwide dark theme across Google’s and Apple’s mobile OSes. The dark mode isn’t automatically applied everywhere, however, and a few popular apps — including Gmail — lack a dark-mode setting. Starting this week, however, Google’s popular mail app is no longer a holdout, as the company is rolling out a dark-mode setting for Gmail on Android 10 on iOS. Google is pushing the update out slowly — over a few weeks — so if you don’t have it yet, Google says it’s coming shortly.
With dark mode, you can conserve a bit of battery life and your phone’s screen will be easier on your eyes at night. Google first added dark mode to an Android Pie update earlier this year, but the theme didn’t show up everywhere. In Android 10, dark mode is much more widespread, and apps that use the default system theme will automatically adopt the new dark mode when you turn it on, inverting dark and light colors. The new version of Apple’s mobile operating system also applies the theme broadly, from wallpaper, widgets and notifications to Calendar and Messages.
