Confirmed by Google: Dark mode on Android helps save battery

Share

Dark mode saves lives. It's always been associated with better battery life on devices, especially mobile devices.

Android used to be completely dark, the entire OS.

Google's Android Dev Summit has been going on since Wednesday morning and was the site for Google's acknowledgement that foldable displays are coming and that Android will support them. Indeed, Google's data showed that the phone used less than a fifth as much power when displaying black as opposed to white. However, it's a long way from here to having the system-wide option (or even the option in all apps) to go dark.

During their presentation, it's quite obvious that the developers were pushing for more Android developers to adopt dark and night modes for their phones. But in Dark Mode, battery consumption on the Pixel drops 63% to 92mA. Google's device draws 250mA while at maximum brightness in normal mode, while Apple's phone was at 230mA. That is pretty insane, and a huge difference.

Banes went on to laud the introduction of dark modes, using the recent YouTube update as an example of the power benefits. Thus, with an AMOLED screen, a black color simply means that none of the red, green or blue pixels are turned on.

Google discussed how they moved in the wrong direction with respect to battery life when they moved from the black theme to the light Material Design theme.

The tech giant Google has now revealed that this dark mode has one last important and very efficient function. The company is also testing the feature in the mobile Google Feed.

Pixel color value can also affect power usage quite a bit, with white being the most power-hungry color. Google routinely bans sketchy apps from its store, but they remain available via sideloading, and their makers don't stop advertising the product just because it's unavailable from the approved channels. The latest example that can be cited here is the YouTube dark theme.

It turns out it's something as easy as switching to dark mode whenever possible. Guess which one was better on battery life? Update, Nov. 9: Added details about saving battery life. The primary aim of the app is to help users to free up space on their phones, and today Google announces that it not only has a new name, but also a new look. It's actually pretty significant.

There are other, non-Google apps out there that do have dark modes, like Twitter.

The dark mode option changes the primary colour theme of an app to the colour black.

The new API gives developers two new ways to update the apps: flexible and immediate. They aren't forcing everyone to move to a dark mode on their app, but they do at least want users to have the choice. Well, hearing this report is a good news for most of us.
