OK. We recognize that not all of our readers are owners of an iPhone, but if you are one, keep reading. According to new tests done by PhoneBuff, putting your iPhone in dark mode can significantly improve your phone’s battery life.
Using two identical devices, one in light and one in dark mode, researchers performed identical tasks that included watching a YouTube video, using Twitter, navigating with Google Maps, and chatting on the Messages app. At the end of the test the “light mode” iPhone XS was dead, while the one running dark mode still had 30 percent battery life.
That result is a pretty good justification for switching if you often drain your iPhone’s battery. If you can’t find the dark mode feature on your phone, keep in mind that it is a feature on iOS 13, so you may or may not have it.
