Slack's doing its bit in the quest to save your phone's battery life: The Bahamascompany just launched dark mode for mobile.

The feature, which recently launched in beta, is now available to everyone.

Turning on dark mode on both iOS and Android is easy: Tap on the three dots in the upper right corner (from channel view), tap Settings, and tap Dark Mode.

The feature will give the channels and the settings windows a white-text-on-dark-background look. The sidebar, which already had a sort of a dark mode look, will stay the same in both dark and normal mode.

With this feature, Slack is following in the footsteps of numerous other apps that have recently added a similar option, including Facebook's Messenger and YouTube.

And if you're frantically looking for the dark mode option in the desktop version of Slack, don't bother: It doesn't exist yet. There's hope ahead, though: Slack has announced it's working on it.
