1Plug the charger into a power outlet.
2Plug one end of the USB cable into the charger (or into the USB port of a
computer).
3Plug the other end of the cable into the micro USB port on your device, with
the USB symbol facing up. The notification light lights up when charging starts.
4When the notification light 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.
If the battery is completely discharged, it may take a few minutes before the notification light
lights up after you connect the charger cable to a power source.
Notes on USB cable usage and battery charging
•To charge your device, Sony strongly recommends that you use only Sony branded
original batteries, a power supply and the USB cable supplied with your device. The
use of third-party products may decrease the performance of your device and/or
pose a risk to your health or safety.
Actual charging times may vary. When tested in laboratory conditions, the approximate
charging time for an empty battery is around 3 hours when utilizing the charger recommended
by Sony for your device. Interrupted charging does not damage the battery. Performance
depends on temperature, signal strength, usage patterns, features selected and voice or data
transmissions. The standby time for this battery is up to 890 hours (the test results are based
on GSMA battery life test technology).

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.
•Turn off Bluetooth® and WLAN connections when you don't need these features.
You can turn them on and off more easily from the Notification panel by dragging
down the status bar.
•Use the STAMINA mode and Low battery mode features to reduce battery
consumption. You can select the power saving mode that best suits the way you use
your device. You can also customise the settings of each power saving mode.
•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 your device to see which applications use the most
power. Your battery consumes more power when you use video and music streaming
applications. Some 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 activate the Airplane mode setting 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 your device's own loudspeakers.
•Keep your device in standby whenever possible. Standby time refers to the time
during which your device is connected to the network and is not being used.
