SAN FRANCISCO: Google has finally confirmed that dark mode on Android phones uses less power and saves battery life.

"Google revealed a bit of information on how your smartphone spends its battery life. They did this at this week's Android Dev Summit, speaking to developers about what they can do in their apps to avoid consuming massive amounts of battery life.

"But this isn't just about that. This is about the biggest factor in battery consumption: screen brightness! And not only that, but screen colour, too," Slash Gear reported late Thursday.

Dark mode essentially changes the overall colour theme of an operating system (OS) or applications to the colour black.

During the presentation, the Internet giant added how dark mode can use 43 per cent less power at full brightness than "normal mode" in the YouTube app which traditionally uses a lot of white, according to Business Insider.

The tech giant reportedly acknowledged its mistake of encouraging app developers to use the colour white for their applications, including its own apps.

Since the inception of Google's "Material Design" initiative, the company had been pushing for the use of colour white, thus, encouraging designers to use white as their primary colour for all apps and interfaces.

    There are obvious energy savings on all OLED/POLED/AMOLED screens because each sub-pixel is individually lit up like a teeny-tiny LED. Black screens = the LEDs are off/less bright = less energy use = Savings. But can an expert please explain how "dark mode" affects battery life on all LCD display phones? What percent of display current affects white-black transformation on a constant back-light level?
