To charge the phone
1 Plug the phone 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 phone, with the
USB symbol facing up. The battery status LED lights up when charging starts. If
the battery is completely discharged, it may take a few minutes before the LED
lights up after you connect the phone charger cable to a power source.
4 When the battery status LED is green, the phone is fully charged. Disconnect the
USB cable from your phone by pulling it straight outwards. Make sure not to bend
the connector when removing the cable from the phone.

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.
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. You do not need to turn off 3G.
• Use the Power Saver feature to reduce battery consumption. You can select the power
saving mode that best suits the way you use your phone. You can also customize the
settings of each power saving mode.
• 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
