The notion already existed and now Google confirms what we already knew. If you want to save battery on your Android smartphone then switch to dark mode "Dark Mode" on your smartphones and mobile devices.
Firstly, the charts recently released by Google show us the impact of this dark mode on battery life. Here it is important not to confuse autonomy with the service life (charge cycles) a battery can withstand over the years.

Second, the comparative charts that Google now provides us allow us to bury any doubts. If you want to get even more out of your smartphone and extend its range you should use dark mode wherever possible.
In this sense, the North American technology shared its findings during the Android Dev Summit. In other words, during the congress dedicated to the Android operating system, programmers as well as software developers.
The impact of dark mode on Android and an OLED screen
Thirdly and as the international press goes, SlashGear is not only the screen brightness that greatly influences battery life. To this important factor we must also add the colors used, something that is especially true in OLED displays. However, on LCD screens the same principle no longer applies, at least with such intensity. Let's look at all the conclusions presented by Google itself, always aware that the "battery" never hurts.
Looking at the graph above, we can see here the amount of energy spent on each pixel on an OLED display when displaying certain colors. Moreover, it should be noted that the maximum brightness is being used here. In short, it is very clear that white is the most energy consuming on an OLED screen.
White is the most energy consuming on an OLED screen
In short, this confirms the widespread view that OLED displays can use less energy if you choose, for example, a dark wallpaper. Therefore, you can improve the autonomy of your Android smartphone by choosing dark mode wherever possible in applications that support it.
Second, Google experts shared their findings on the impact of "Night Mode" on energy consumption. To do this they can use their Android smartphone, the Google Pixel against the competition, in this case the iPhone 7.
The importance of color in the autonomy of your Android smartphone
However, it should be noted that not all Android smartphones will enjoy "Night Mode" in the same way. Therefore, while proving that software can be used to optimize power consumption, not all devices behave the same way.
Google also shared its findings regarding the impact of color on different applications. How an application's particular color palette could use more or less energy. That is, cause an increase or decrease in energy consumption.
Google recognizes the impact of dark mode on their Android apps
Again, the brighter an app's color scheme is, the more energy it consumes. There is an easy-to-interpret pattern here that brings us back to the importance of dark mode.
In short, if you have an Android smartphone with an OLED screen then you can easily squeeze a little more autonomy. This will be enough to decrease brightness, use dark wallpapers / themes as well as dark mode whenever possible.
The impact of maximum brightness on OLED screen smartphones
Google also studied the different behavior in maximum brightness situations on an OLED screen. In short, it concluded that black, even at maximum brightness, consumes virtually no power. Already white is the color that uses most energy, especially with the maximum brightness.
Google even made a moment my fault, recognizing that so far it has stimulated the opposite behavior. Above all with your Material Design which brought us several very light colored Android apps.
Incidentally, the vast majority of Google applications for Android smartphones turn out to have a very clear complexion. However, US technology will now make dark mode available for most of its smartphone apps.
In short, realizing that until now has stimulated the development of apps whose interface is predominantly white. Something that ends up spending more energy, the company wants to reverse the behavior.
