•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.

When your phone is on and left idle for a set period of time, the screen darkens to save battery power, and locks automatically. This lock prevents unwanted actions on the touchscreen when you are not using it. You can also set personal locks to protect your subscription and make sure only you can access your phone content.
