Battery Life Improvements
If you own an older Nexus phone or tablet, you should be excited about the battery life improvements coming with the update.
Thanks to Google's Android Marshmallow Developer beta, we know that Android 6.0 Marshmallow and its various features actually work to conserve battery life on Nexus devices.
This is mostly thanks to a feature Google's calling Doze. The feature recognizes when a device hasn't been used for awhile and it stops apps or puts them into a low-power state to conserve standby battery life. We think you're going to love it.
