The Basics
Charging with USB
You can use your computer to charge your phone. To be able to charge with
the USB cable, you need to have the necessary USB drivers installed on
your PC first. Connect one end of the USB cable to the Accessory/Charger
Port on your phone and connect the other end to a USB port on your PC. It
is best to use the rear USB port when connecting to a desktop PC. The USB
hub should be powered by an external power source.
Optimizing Battery Life
You can extend your battery’s life between charges by turning off features
that run in the background. You can also monitor how applications and
system resources consume battery power.
To stop applications from running in the background
From the Home screen, touch the Apps Key > Settings > Apps >
Running tab and select the items that are no longer in use and touch Stop.
Tips to extend the life of your battery

Turn off radio communications that you aren’t using. If you aren’t
using Wi-Fi, Bluetooth, or GPS, use the Settings menu to turn them
off (Note that the GPS receiver is only turned on when you’re using an
application that makes use of it).
㻌
Turn down screen brightness and set a shorter screen timeout.
㻌
Turn off automatic syncing for Gmail, Calendar, Contacts, and other
applications if you don’t need it.

GPS connection, Bluetooth power, display brightness, and syncing
activity.

From the Home screen, touch the Apps Key
> Settings >
About phone > Battery.
