Dark Mode is not just more aesthetically pleasing to many people, there are real battery-life boosts to be had — and Google has the numbers to prove it. From a report: Touting the benefits of Dark Mode, Google showed that with screen brightness set to 50 percent, using YouTube with Dark Mode enabled resulted in 14 percent less battery usage. With screen brightness set to 100 percent, the saving jumps to 60 percent. These are not numbers to be sniffed at, but the biggest savings are to be seen on phones with AMOLED screens as anything that is black does not require pixels to be powered. Slides from the event show Google comparing the power usage of its own Pixel phone with an LCD iPhone 7. It shows a 63 percent battery saving when displaying a screenshot of Google Maps in normal and night mode.
