Airplane mode

In Airplane mode, your phone's network and radio transceivers are turned off to prevent disturbance to sensitive equipment. However, you can still play games, listen to music, watch videos and other content, as long as all this content is saved on your memory card. You can also be notified by alarms, if alarms are activated.

Turning on Airplane mode reduces battery consumption.

To turn on Airplane mode

1From your Home screen, tap .

2Find and tap Settings > Wireless & networks.

3Mark the Airplane mode checkbox.

You can also select Airplane mode from the Phone options menu. To access the Phone options menu, press and hold the power key .

Battery

Your Android™ phone keeps you connected and updated wherever you are. This affects the battery life of your phone. Below are some tips on how to prolong battery life while still staying connected and up to date.

Battery performance

Standby time, a common term when it comes to battery performance, refers to the time during which the phone is connected to the network and is not being used. The more time your phone is in standby and not otherwise in operation, the longer the battery lasts.

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. You can do this from Settings > Wireless & networks > 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 Status switch widget to your Home screen. You do not need to turn off 3G.

•Set your synchronisation applications (used to synchronise your email, calendar and contacts), to synchronise manually. You can also synchronise automatically, but increase the 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 since multitasking affects the battery performance.

•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 Ericsson original handsfree device to listen to music. This consumes less battery power than when you listen to music through the phone's loudspeakers.
