Charging with the USB Cable
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 USB/Charger Port
on your phone (as shown above) and connect the other end to a USB port
on your PC. It's best to use the rear USB port when connecting to a desktop
PC. The USB hub should be powered by an external power source.
NOTE You may experience a slower charging rate when charging from your computer.
