Google's Wear OS developer preview brings dark UI, improved battery life & more

31 March 2018 2

Earlier this month, Google rebranded Android Wear as Wear OS and has now released a new developer preview for the same. One of the biggest changes the new iteration brings is the ability to preserve battery life. Let’s take a look at what else the new update brings for the users.

The Wear OS developer preview is currently available exclusively for the Huawei Watch 2 Bluetooth and the Huawei Watch 2 Classic Bluetooth wearables. Users who want to try the update will have to flash the developer preview manually, so continue if you know what you are doing.

Background activity for apps is being limited almost completely as Google flatly states that, “apps will no longer be allowed to run in the background unless the watch is on the charger.” The company also tells developers to “remove background services” functionality for their Android Wear apps. To further increase the battery life, Bluetooth, Wi-Fi, and cellular radios will shut down when the watch detects that it is no longer on your wrist. The only exceptions include if an app is requesting a high bandwidth network or if the watch is on the charger.

Other features in the Wear OS include a new Dark UI system theme that will improve readability of content on the wearable. The dark background for the notifications stream and system launcher is now the default theme and will improve the glanceability for wear apps.
