Google: Here's why dark mode massively extends your OLED phone's battery life

Google: Here's why dark mode massively extends your OLED phone's battery life

Now when you view your app drawer or the quick-settings card (swipe down from the top of the screen), it'll be in dark mode. There was another stat that shows that 2016 model Pixel smartphone at a maximum brightness consumed around 330mA of power while its just 60mA of power used when the display is set at maximum Black. On Google Maps, even at full brightness, using night mode can save about 30 percent of the battery. It shows that at 50-percent brightness, it's only a 14-percent difference, between dark and normal mode.


We know the advantages of OLED screens. And when it comes to Black and White both are at the opposite ends in power consumption. Google has somehow made up for the excessive use of whites in the Material Theme design with the Dark Mode. The company acknowledged that white is "less than ideal". Now, they seem to be actively advocating for developers to introduce dark modes on their apps, too.


Obviously, more brightness means quicker power draw. There is another reason for Google to bring the dark more, i.e. the smartphones with AMOLED panels will be saving battery life while in the dark mode. But you won't really find true dark modes for any of them.


Another interesting tidbit from the session is that using Night Mode to filter out some of the blue light during the late hours can actually reduce power draw by as much as 63%, so it's good for your eyes and your phone's battery. But there may be independent apps that may offer users dark modes, with YouTube being one such example. Some of these were from teams that were "dogfooding" the app (this is how Google tests apps and features internally before rolling them out) that were sent out to people outside of Google by mistake. From a list of options, select the black theme or any darker shade to suit your preference. Guess which one was better on battery life? It's been encouraging developers to adopt the new Material Design guidelines, which provide more freedom than the old version. As well as more closely resembling other Google apps, the redesigned Files by Google has a look that is cleaner and more modern.
