applications run in the background when you open
another application. There’s no need to quit an

Understanding Your Phone
Charging your Phone
Your LG Optimus One comes with a wall adapter
and a USB cable which connect together to charge
your phone. To charge your phone:
NOTICE: Please use only an approved
charging accessory to charge your LG phone.
Improper handling of the Accessory/Charger
Port, as well as the use of an incompatible
charger, may cause damage to your phone and
void the warranty.
Connect the wall adapter and USB cable as
1.
shown. The LG logo on the USB cable should
face toward you.
LG Optimus One | User Guide
26
Gently uncover the Accessory/Charger port, then
2.
plug one end of the USB cable into the phone’s
Accessory/Charger Port and the other end
into an electrical outlet. The charge time varies
depending upon the battery level.
Battery temperature protection
Though extremely rare, if the battery becomes
overheated, the phone will automatically turn off.
Battery charge level
You can find the battery charge level at the top right
of the screen. When the battery level becomes low,
the phone will notify you. Once the battery level
becomes exceedingly low, the phone will shut off
without notice. As a result, unsaved items may be
lost.
27
Understanding Your Phone
NOTE: The battery must be fully charged initially
to improve battery lifetime. The LG Optimus One
has an internal antenna. Be careful not to scratch
or damage this rear area, as that will cause loss
of performance.
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.
NOTES:
Low-power USB ports are not supported,
•
such as the USB port on your keyboard or
bus-powered USB hub.
The LG USB Driver is downloadable from
