Xperia™ Z - Intelligent battery life management

Battery STAMINA Mode manages power consumption more intelligently, saving energy when your Xperia Z is in standby. It knows when your screen is off and shuts down the battery-draining apps you don't need, starting them up again when the screen is back on. Tailor to your needs easily by customising which apps you want to receive push notifications from, even in stamina mode.
