Improving battery performance

The following tips can help you improve battery performance:
Charge your device 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.
You can do this from Settings > More... > Mobile networks > Mobile data traffic.
This setting does not prevent your device 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.
Set your synchronization applications (used to synchronize your email, calendar, and
•
contacts) to synchronize manually. You can also synchronize automatically, but
increase the synchronization intervals.
Check the battery usage menu in the 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 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 device or use Airplane mode 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 the device's loudspeakers.
Keep your device in standby whenever possible. Standby time refers to the time
•
during which the device is connected to the network and is not being used.
