Google tells developers that Dark Mode saves battery life

Posted November 09, 2018

This is when Google realized its mistake: it made white the default background color in its Material Design guidelines, which Google admits isnt using the phone to its best efficiency, not when Night Mode could potentially save a good deal of power. The Pixel's current draw was 92mA, while the iPhone 7's was 230mA. Another chart shows that a 2016 Pixel, with the screen at at maximum brightness, consumes approximately 330mA of power compared to approximately 60mA of power with the display set at maximum black.

Like the LCD panels, the AMOLED displays do not use a backlight and a black screen does not require Red, Green or Blue pixels which intern saves battery life.

It turns out it's something as easy as switching to dark mode whenever possible. Dark Mode helps power conservation in devices with OLED screens as the pixels are completely turned off unlike LCDs where power is required to display both white and dark shades. The company acknowledged that white is "less than ideal". This can save up to 43% battery usage during video playback and 60% when paused (with the phone set to 100% brightness). You may have to manually enable Dark Mode on different applications. Apple's iPhone UI, meanwhile, is also heavy on white, and there's no dedicated dark mode on iPhone either.

Results between the two phones were comparable in Normal Mode, though results showed a much greater disparity with Night Mode. Which is why having more ways to get users to update their apps is a good thing for developers.

The other option is what Google is calling a flexible update.

Jack Wallen lists flexibility, Google integration, and open source as reasons why he chooses the Android operating system over iOS for his mobile devices.

Google has also announced that in less than a year, the app has a whopping 30 million monthly users, which I am sure is earning Google some $$$.
