Improving battery performance
The following tips can help you improve battery performance:
Charge your phone often. This will not affect the lifetime of the battery.
Downloading data from the Internet is power consuming. When you're not using the
Internet, you can save power by disabling all data connections over mobile networks.
This setting does not prevent your phone from transmitting data over other wireless
networks.
Turn off GPS, Bluetooth™ and Wi-Fi® 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. You do not need to turn off 3G.
Use the Power Saver feature to reduce battery consumption. You can select the
power saving mode that best suits the way you use your phone. 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 the phone 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 Android Market™ applications also consume
more power.
Close and exit applications that you are not using.
Lower the screen display brightness level.
Turn off your phone or activate the Airplane mode setting if you are in an area with
no network coverage. Otherwise, your phone 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 the phone's loudspeakers.
Keep your phone in standby whenever possible. Standby time refers to the time
during which the phone is connected to the network and is not being used.
