Android Doze helps handsets get smarter with battery powerWith the help of motion detection, Android Doze enables handsets to "doze" into a deeper sleep when inactive, and thus improves battery life.
In the spirit of improving the core experience, we're changing Android and M to be smarter about managing power through a new feature we call Doze. Now many of us have bursts of [INAUDIBLE] with our devices, especially with tablets. For example, you might leave your tablet on your coffee table or your nightstand all day, only to pick it up and use it to read a book or watch a movie in the evening. With M, Android uses signficant motion detection to learn if a device has been left unattended for an extended period of time. In that case, it will exponentially back off background activity, to go into a deeper sleep state. So what we're doing is we're trading off a little bit of app freshness for longer battery life. And we call it dozing because while the device is asleep it's still possible for the device to trigger a real time alarm or to respond to incoming chat requests through high priority messages. So how well does this work? Well, we took two Nexus 9s and we put Lollipop in one and M on the other, and then we loaded both up with the same accounts with lots and lots of applications. We put the two devices side by side and measure power. And I'm happy to say that we're seeing devices with M lasting up to two times longer in standby. [APPLAUSE]
