13 The Basics
Charging with USB
NOTE
Make sure that the USB
logo on the cable is facing
upward before inserting the
USB Cable into the phone.
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 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.
Tips to extend the life of your battery
㻌  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.
㻌  Use the Power saver feature in the Settings menu or the My Settings
widget to control data activity, Wi-Fi connection, Bluetooth connection,
and power used for the device such as screen brightness and phone
ringtone.
