Samsung's experimental Vulkan-based TouchWiz launcher can extend the battery life of the S7 edge
According to Samsung engineers, migrating the standard TouchWiz launcher to Vulkan has resulted in a 6% battery consumption decrease when the handset performs basic tasks such as opening the app tray or scrolling pages. On a 3600mAh battery such as the one inside the Samsung Galaxy S7 edge, this can lead to 40 extra minutes of battery life.
Fortunately for the Android ecosystem as a whole, the Vulkan API will soon extend to all new Android smartphones. A couple of weeks ago, Google unveiled the second Android N Developer Preview. Among the highlighted changes brought by the new update, the most notable one is considered to be the new Vulkan graphics rendering system.
Although Vulkan's most notable application are 3D-intensive mobile games, the new graphics rendering system can also make improvements in the way that handsets draw 2D graphics such as the system's user interface, and Samsung's Vulkan-based TouchWiz launcher is probably just scratching the surface of what's possible using the Vulkan API.
Unfortunately, the new TouchWiz launcher is not ready to reach end users just yet. However, we'll be interested in learning more about what Vulkan can do to solve what many consider as being the worst problem with modern smartphones: battery life.
