Many users who know that the inclusion of "night mode" helps significantly extend the operating time of a smartphone with an OLED screen. Bright and bright images spend more energy on the backlight of each pixel, but when the dot is black – that is, it is turned off, practically does not consume battery power.
This was called by Google to developers at this week's Android Dev Summit Conference. Using the example of the Pixel smartphone itself, the company shows that the most "greedy" white color consumes 320 mA, while black only spends around 50 mA. The advantages of "night mode" become clearer when the display of the device is not locked at 100 percent brightness. In normal mode, the YouTube application consumes 239 mA, but when the dark theme is activated, only 96 mA.
At the same time, Google acknowledged that they themselves underestimated the importance of "night mode". The search engine's own manual on "material" design styles requires developers to design programs with solid and solid colors with white dominance.
In this case, the company has promised to make more applications that are less energy intensive. "Dark" themes are available on YouTube and Android "Post", and will soon be added to "Phones" and personalized feeds on Google Search. Android itself can be transferred to "night mode": to do this, you must drag the shutter and activate this function on the quick access panel.
The new flagship smartphone equipped with three cameras, a 3D face scanner, high-resolution OLED panels, and other energy-intensive technologies continues to charge less than older models. To expand work, smartphone owners with OLED panels are recommended to reduce screen brightness as much as possible so that less energy is spent on backlights, connect to Wi-Fi than LTE networks, and on Android use energy-saving modes.
