networks.

Turn off Bluetooth™ and WLAN when you don't need these features. You can turn
them on and off more easily by adding the Quick settings widget to your Home
screen.
•
Use the STAMINA mode and Low battery mode features to reduce battery
consumption. You can select the power saving mode that best suits the way you use
your device. You can also customise the settings of each power saving mode.
•
Set your synchronisation applications (used to synchronise your email, calendar and
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. Some applications 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 mode whenever possible. Standby time refers to the
time during your device is connected to the network and is not being used.
