Google: Here's why dark mode massively extends your OLED phone's battery life

At its annual I/O developer conference, Google showed a graph illustrating the relationship between screen brightness and power draw. If you crank brightness on your phone, a damn dark theme on your keyboard could save you 21%. That is pretty insane, and a huge difference. Thus, with an AMOLED screen, a black color simply means that none of the red, green or blue pixels are turned on.

Tap on the toggle for "Dark theme" to enable it. Which is always a good thing with smartphones, especially those that have smaller batteries, or might be a bit older.

As Google presenter Chris Banes noted, the screen itself is one of the biggest drains on battery, so the company has been looking at ways developers could minimize the screen's power usage. Switch to dark mode on the micro-blogging platform by going into Settings and Privacy Display and sound Turn on Night Mode.

While Google will likely continue to release "Dark Mode" in their apps in the near future - it is also testing the feature in the mobile Google Feed - it has reportedly drawn the line at adding a system-wide night mode.


In addition to the YouTube application, Google's Messages app also has a dark mode. So if you're serious about saving battery, dark mode on YouTube is definitely worth toggling on. So we do know that Google's teams are working on dark modes for different apps from Google. From a list of options, select the black theme or any darker shade to suit your preference.

WhatsApp is clearly a popular messaging app with over a billion users, but it lacks a dark mode. Google suggested today that Files Go recently had 30-million monthly users worldwide. It's actually pretty significant.

Files Go has been rebranded Files by Google, and the updated version of the app is starting to roll out now. As the name implies, Dark Mode reverses the white background to black which is said to be more comforting to eyes.

Google is giving developers tools to push users into updating their apps. They aren't forcing everyone to move to a dark mode on their app, but they do at least want users to have the choice.
