On Friday Google hosted its Android Dev Summit 2018. Among all the presentation, there was a presentation where Google talked about power consumption and how the phone drains its battery life. Google also shared a very interesting conclusion that Using Android Dark Mode improves battery life of the smartphones.
Android Dark mode is an option in your smartphone that changes the overall color theme of phones. Many people are already using the Android Dark Mode and they already have an understating that it saves the battery life but this new information provided by Google gives good context and may help people in saving battery.
In one piece of data, Google showed the dark mode can use 43% less power at full brightness than “normal mode” in the YouTube app, which uses a lot of white.
Google also acknowledged that it encouraged app developers to use the color white for their apps and this was a mistake. It was also found the battery-saving effects of dark modes are also more apparent on OLED displays, which most top smartphones use these days, compared to more traditional LCD displays.
OLED displays don’t shine their pixels when displaying the color black. In essence, pixels displaying the color black are actually turned off and are using very little power – if any. LCD displays, on the other hand, have a backlight that’s always shining, even when displaying the color black.
Battery life is a major reason for every operating system and many app developers are offering a dark mode for this. In the future, we will see more apps getting the dark mode option.
