This week we noticed that we talked about using an AMOLED display on a mobile phone. Using your phone in "dark" mode with a black background will save you some battery life. This is because the screen technology displays black rather than white and consumes less energy. And, regardless of the color displayed on the screen, energy consumption is different from the same LCD.
Some manufacturers have made this possible by setting the phone to dark mode (especially with a black background in the configuration menu or application list), but now Google records the number. According to the company, this savings is between 14% and 60% (in the latter case a blank screen with maximum brightness). Also, displaying blue on the screen consumes 25% more energy than using red or green on average. White people consume a lot and consume less.
Samsung, LG and Motorola will display a notification when the screen is blocked. Power consumption is very low because only the darkest part and the least part are brightened. Samsung said that in the case of the Galaxy S7, the clock always has 1% of the battery per hour, which is the time (represented by a small brightness white on the black background).
At the last meeting for developers last week,
After the company announced support for folding screens, Google noticed that white consumes more energy than black, and opened up the possibility of using dark backgrounds in the original way.
Because they already offer iOS (but it only affects models with OLED screens like iPhone X and XS), macOS and Windows 10
Like the company itself did on YouTube (Twitter has a dark mode, for example, activated in the same way as the map app when done at night).
However, most companies that apply "themes" to operating systems such as Samsung, Huawei, LG, or Sony already offer alternatives that use black backgrounds rather than specific interfaces.
