Android M is set to hit smartphones later this year with some exciting new features. The most welcome of these are two new battery saving features that almost treble battery life - Doze and App Standby.
Doze puts your phone into an ultra-deep sleep when you leave it alone for a while. That means auto-syncing and other open tasks are all paused, automatically restarting when you pick the phone up again.
App Standby cuts in a lot more quickly than Doze. In fact, it starts working as soon as you unplug your phone. It knows which apps you don’t really use and stops them from getting network support. That means they can’t keep connecting to the internet in the background when you don’t want them to. But when you start charging your phone again, all your apps will be able to get online.
With App Standby, we’d imagine there’s a feature that lets you create a list of apps that can always get online, just in case there’s something you don’t really use, but need updates from when they come through.
Now you know the theory of Android M’s battery saving features, we bet you’re wondering whether they’ll really work. Well, someone’s installed the Android M Developer Preview (a very early version of the new software) onto a Nexus 5 and compared its standby battery life to that of a Nexus 5 running the latest Lollipop 5.1.1 software.
After 8 hours on standby, the Lollipop Nexus used 4% of its battery, the Android M one only used 1.5%. 24 hours into the test, the old software had eaten 12% of the battery, the new software was at 4.5%. After two full days, the Nexus running Android 5.1.1 had got through nearly a quarter of its battery, 24%, the Android M Nexus had only used 9%.
The projected standby time of the Android Lollipop Nexus 5 was just 200 hours, compared to 533 hours for the Android M phone. That’s a massive 270% increase in standby time.
We really can’t wait for Android M now.
