Android P has its own dark mode.

On Friday, Google hosted its Dev Dev Summit 2018 for Android, where it talked about everything about Android. In one of his presentations, Google talked about the energy consumption and the way your phone drains his battery life. During this presentation, Google made an interesting conclusion: the dark mode saves battery on Android.
Of course, some people may have already worked under this assumption. But the information and research shared by Google is a good context and can help you save the battery of your phone.
Pixel vs. iPhone 7 exhaust the battery.

Google compared the amount of current (milliamps or mA) Google Pixel and iPhone 7 Aspire when you view a screen capture with the maximum brightness (see above). Although the amount of power is comparable for both phones, this number decreases by 63% when you use the pixel at maximum brightness in dark mode.

Google has also broken down the amount of current used by different colors when the pixel is set to the maximum brightness. His data shows that the white color uses the most current color, the blue coming in second. Black consumes as little power as possible. Red and green are almost linked and at the lower end of the spectrum, consuming about half as much current as blue.
Google then measured the impact of pixel color on power (in mW). The results show which colors and color combinations consume the most power.
Blue always has the highest energy consumption (compared to red and green alone).

These data tell us two things: First, the night mode or night mode will significantly reduce the amount of battery your phone uses. Second, the colors on your screen also make a difference. So, if you want to save the battery, you can turn on the dark mode or swap the color balance to use less white / blue light (much like Night Shift on iPhone turns your screen into the hottest part of the color spectrum).
There was a moment in the presentation of Google where he admitted that Android developers were invited to use more white as the main color for layouts. Google's research implies that it makes Android apps more energy-hungry. Android Pie has a dark mode this can counteract that, however.
