With phone displays getting more and more pixel-dense and faster refresh rates, like the OnePlus 9, batteries can drain even faster. Thanks to OLED screens, knowing how to enable dark mode on your OnePlus phone is a thing that not only looks cool but can also save you some battery life. You see, OLED panels don't activate any pixels when representing "black" — instead, black represents what it really is, the absence of light. By not activating large swaths of pixels, you inevitably save battery life. While it's not as simple as a quick settings shortcut like on Samsung Galaxy phones, enabling dark mode on a OnePlus phone is still darn simple.

How to enable dark mode on your OnePlus phone

  1. Open the Settings app from either the app drawer or from the quick settings in the notification pane.
  2. Tap on Display.
  3. Tap on Dark Mode.

By giving Dark Mode a proper set of easy-to-use toggles, you can choose to live on the dark side all the time or schedule your phone to adjust from light to dark automatically. Much like being able to turn on your phone's blue-light filter based on the time of day, you can do the same thing for Dark Mode.

OnePlus's implementation of a system-wide theming system isn't near the level of what Samsung offers. Still, it's better than what Pixel phones bring. From the ability to use some of the best icon packs for Android on OnePlus phones to simply changing out the system accent colors, the world is your oyster.
