Dark mode is one of the features of the tent for iOS 13 this year and is rapidly spreading to third-party apps and websites. A new test from PhoneBuff this weekend aims to find out how much better the dark mode is for the battery life than the Light mode.

Using the iPhone XS as a test device, PhoneBuff uses robotic weapons to do different things through iOS while in Light and Dark Mode. This included using the Messages app, navigating Google Maps, watching YouTube videos, and more.
The end result is actually quite impressive. The PhoneBuff test found that the iPhone XS uses a depleted dark mode battery at a much slower pace than the iPhone XS using Light mode. When the iPhone XS of light mode died, the iPhone XS with dark mode still had 30 percent battery life.
Here is a complete chart showing the comparison:
One important detail here is that the test was performed with displays set to a brightness of 200 nits. You will notice some differences with lighter and darker brightness settings, but in all scenarios iPhone XS using Dark Mode exceeds that using Light mode.
Another important detail is that Dark Mode has the greatest effects on battery life for devices that have OLED displays. This includes the iPhone X, iPhone XS and iPhone 11 Pro, but not the iPhone XR or iPhone 11.
