Dark mode is an optional setting that changes the background of an app’s interface, like Facebook, from white to black, and text from black to white.
Dark mode consumes less battery on your device because displaying darker pixels on an LED screen uses less power than displaying white ones. Some people also find that it’s less straining on the eyes, and many believe that the reduced blue light helps them sleep better, though it’s not scientifically proven.
Facebook dark mode
All Facebook users have access to the dark mode feature in any desktop web browser, like Google Chrome and Safari, for both PC and Mac computers.
When dark mode first rolled out on the Facebook mobile app, it was only available to some users during beta testing. But dark mode should now be available to all users of the Facebook mobile app for iPhone and Android.
Here’s how to enable dark mode on the Facebook website, or on the Facebook mobile app for iPhone or Android.
