During a presentation at the 2018 Android Dev Summit, Google urged its developers to use darker colors in their apps to get the best battery life on the end user's phone. When an OLED screen displays black, it doesn't really display anything. Google's device draws 250mA while at maximum brightness in normal mode, while Apple's phone was at 230mA. As the reduced brightness of the mode would help smartphones and tablets immensely in their conservation of battery power.
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.
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. They discussed that using a dark theme in their keyboard, GBoard, can reduce power consumption by up to 21%.
Note that changing to Dark Mode only converts the UI colour to black background. The company plans to introduce the dark mode to its Phone app after getting it to YouTube and Android Messages. At 100% screen brightness, the dark interface is saving a whopping 60% of screen energy. This is the first thing that appears on the phone when you unlock so it makes sense to have a dark wallpaper. For instance, YouTube users can manually activate Dark Mode by following these steps.

How much China impacts Google's statistical modeling is hard to say; the company did not immediately respond to a request for comment. Again in the Android N beta, we saw dark mode. Twitter with a dark theme is less blinding than a day theme that's mostly white, especially when you're looking at it in the dark or in places that aren't bright (like bars, restaurants, etc.). Google is just priming the pump with all these white apps. The latest example that can be cited here is the YouTube dark theme. Guess which one was better on battery life?
Google are rolling out a new In-App Updates API that will let apps updated while still running.
However, the most informative news from the session concerns the use of color.
