contacts) to synchronise manually. You can also synchronise automatically, but
increase the synchronisation intervals.
•Check the battery usage menu in your device to see which applications use the most
power. Your battery consumes more power when you use video and music streaming
applications, such as YouTube™. Some applications downloaded from Google
Play™ may also consume more power.
•Close and exit applications that you are not using.
•Lower the screen display brightness level.
•Turn off your device or activate the Airplane mode setting if you are in an area with
no network coverage. Otherwise, your device repeatedly scans for available
networks, and this consumes power.
•Use a Sony™ original handsfree device to listen to music. Handsfree devices
demand less battery power than your device's own loudspeakers.
•Keep your device in standby whenever possible. Standby time refers to the time
during which your device is connected to the network and is not being used.
•Disable any live wallpaper.
