iOS 13’s Dark Mode looks awesome, but it also can boost iPhone battery life. How much more time between charges will you really get using Dark Mode?

You can see the dramatic difference for yourself in a new test video.

iOS 13 Dark Mode battery life

Dark Mode boosts iPhone battery life because, at least on phones with OLED screens, black pixels are turned off instead of being backlit. See how much extra work or play time you can squeeze out of an iPhone in the video from PhoneBuff:

Using an iPhone XS for the test, PhoneBuff used robot arms to carry out various identical functions in regular light mode and Dark Mode. Tasks included using the Messages app, navigating with Google Maps, and viewing a video.

The results showed that Dark Mode really does extend the battery life of a handset. When the iPhone XS in regular mode died, the version running Dark Mode still had almost one-third of its battery power left.

As more and more developers of third-party apps add Dark Mode support, the battery boost should increase. So, a future Dark Mode test could show even better results.

This is one for OLED iPhone owners

It’s important to remember that this effect is the greatest when it comes to OLED devices. That means people with an iPhone X, XS, XS Max, iPhone 11 Pro or iPhone 11 Pro Max will get the most benefit. However, those (such as myself) with an iPhone XR or iPhone 11 will not.
