Doze - For Better Battery Life

We all know that data is one of the biggest power drain. If you keep your data on all the day, apps can run out of full battery even without using your phone. When screen is off, Doze prevents your apps from sending or receiving data without disabling your Wi-Fi or 2G/3G/4G data. In this way it adds more hours to standby time and makes significant difference to battery life.
