WARNING: Use only Sprint-approved or LG-approved batteries and chargers with your

Battery Capacity
Your phone is equipped with a Lithium Ion (Li-Ion) battery. It allows you to recharge your battery
before it is fully drained. The battery provides up to 7.0 hours of continuous digital talk time.
When the battery reaches 5% of its capacity, the battery icon blinks. When there are
approximately two minutes of talk time left, the phone can sound an audible alert and then turn
off.
Note: Long backlight settings, searching for service, using vibrate mode, browser use, and
other variables may reduce the battery‟s talk and standby times.
Tip: Watch your phone's battery level indicator and charge the battery before it runs out of
power.
Install the Battery
► See Set Up Your Phone.
Remove the Battery
1. Make sure the power is turned off so that you don‟t lose any unsaved items.
2. Lift the back cover using the fingertip cutout located at the bottom of the phone and
remove it.
3. Lift the battery using the fingertip cutout and remove it from the phone.
WARNING: Do not handle a damaged or leaking Li-Ion battery as you can be burned.
Charge the Battery
Keeping track of your battery‟s charge is important. If your battery level becomes too low, your
phone automatically turns off and you will lose any information you were just working on.
Always use a Sprint-approved or LG-approved desktop charger, travel charger, or vehicle power
adapter to charge your battery.
1. Connect the charging adapter and USB cable as shown; the LG logo on the charging
adapter should face toward you.
Phone Basics 15
2. Plug one end of the USB cable into the phone's Charger/Accessory Port and the other
end into an electrical outlet. The charge time varies depending upon the battery level.
With the Sprint-approved Li-Ion battery, you can recharge the battery before it becomes
completely drained.
Battery Temperature Protection
Though extremely rare, if the battery becomes overheated, the phone will automatically turn off.
Charge with USB
You can use your computer to charge your phone. To be able to charge with the USB cable,
you need to install the necessary USB drivers on your computer first. Connect one end of the
USB cable to the Charger/Accessory Port on your phone and connect the other end to a USB
port on your computer. It is best to use the rear USB port when connecting to a desktop
computer. The USB hub should be powered by an external power source.
Note: 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 the following site: http://www.lg.com/us/ >
Select SUPPORT. In the Search box next to SEARCH PRODUCT SUPPORT, enter the
model name or name and click SEARCH. Click the model. On the PRODUCT
SUPPORT page, click on Software Update & Drivers.
Always unplug the charger from the wall socket after the phone is fully charged to save
unnecessary power consumption of the charger.
Extend Your 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.

periodically query the GPS satellites for your current location; each query drains your
battery. (See GPS Satellites.)

Repeating this process of a complete discharge and recharge can over time reduce the
storage capacity of any battery.
● Turn off Automatic application sync. (See Synchronize Accounts.)

GPS, Synchronization, or LCD brightness setting. (See Add and Remove Widgets on the
