On February 18, 2019, Xiaomi’s executive director, Lee Tsun, on his official website in the Weibo social network, said that the company has found a way to increase the time of work on one charge, more than twice. Due to a special innovation that will be embedded in the flagship Mi 9, its owners will be able to increase autonomy by as much as 83%, without using any kind of energy saving mode by reducing overall performance.
All this became possible due to the fact that the “box” in the firmware MIUI 10 based on Android 9.0 Pie for the smartphone Xiaomi Mi 9 will be built in dark mode, with the activation of which battery life will increase to 83%. This result was achieved thanks to features of OLED matrices, which spend much less power on black and dark colors. That’s why the developers have decided to add to the operating system support night mode, which can be used on a permanent basis.
In the future, the night mode will appear in all other Xiaomi smartphones that were released to the market over the past 2 to 3 years. Models that have an OLED screen can work much more than usual. Such an innovation will absolutely appeal to all users to taste, but you must understand and take into account that in the framework of its testing, the Chinese brand used only installed on the phone applications, so when using third-party applications without a dark theme, the autonomous registration is unlikely to be able to increase by as much as 83%. Most likely, the increase will be at the level of 50%.
