    Battery

    Charging the battery

    Your phone battery is partly charged when you buy the phone. It may take a few minutes before the battery icon Icn sony stat sys battery charge anim3 appears on the screen when you connect the phone charger cable to a power source, such as a USB port or a phone charger. You can still use your phone while it is charging. Charging the phone over a long period of time, for example, overnight, does not damage the battery or the phone.

    NoteThe battery will start to discharge a little after it is fully charged and then charges again after a certain time when the phone charger is connected. This is to extend battery life and may result in the charge status showing a level below 100 percent.

    To charge your device

    Charging the Sony Xperia™ E dual
    1. Plug the charger into a power outlet.
    2. Plug one end of the USB cable into the charger (or into the USB port of a computer).
    3. Plug the other end of the cable into the micro USB port on your device, with the USB symbol facing up. The battery status LED lights up when charging starts.
    4. When the battery status LED is green, the device is fully charged. Disconnect the USB cable from your device by pulling it straight outwards. Make sure not to bend the connector when removing the cable from the device.
    NoteIf the battery is completely discharged, it may take a few minutes before the LED lights up after you connect the charger cable to a power source.

    Battery LED status

    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 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 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.

    To access the battery usage menu

    1. From your Home screen, tap Icn sony home apptray normal .
    2. Find and tap Settings > Battery to see which installed applications consume the most battery power.
