During the Android Dev Summit, it seems that Google has confirmed that dark mode is better for overall battery life on Android. The company showed off a presentation slide where an app in dark mode and in max brightness draws considerably less power than an app that uses a lot of white in its design.
Ironically enough as many have pointed out, Google’s apps tend to be filled with white, although to Google’s credit, apps such as YouTube and Android Messages have gotten the option to enable dark mode, which we suppose is a good start. There have been reports in the past suggesting that Android could get a system-wide dark mode, but for whatever reason Google has constantly delayed such a feature.
Perhaps these findings could prompt Google to double down on the feature, but if you’re trying to squeeze as much battery life out of your Android phone as possible, perhaps consider using dark mode on your apps as much as possible.
