Google is now looking to improve battery life with a feature called Doze. This is a new technology that learns over time and detects when your device is motionless and not being used, so it can be sent your device into a deep sleep mode. Once your phone is set to Doze, it checks for updates from apps less frequently, while still staying responsive for calls, messages, and other similar things. Google claims that internal tests have showed double the battery life on standby mode, when compared to Android 5.0.
This feature will help to backup your apps, app cache, app history on Google Cloud and restore it when required.
