Improving battery performance

The following tips can help you improve battery performance:

•Charge your phone frequently. 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 > Wireless & networks > Mobile networks > Data enabled. 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.

•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 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 use Airplane mode 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.
