Charge the Battery
Your device is powered by a rechargeable, standard
Li-Ion battery. A Wall/USB Charger (charging head
and USB cable) is included with the device for
charging the battery from any standard outlet.
The battery comes partially charged. A fully
discharged battery requires up to four hours of
charge time. You can use the device while charging.
Caution: Use only Samsung-approved charging
devices and batteries. Samsung accessories are
designed to maximize battery life. Using other
accessories may invalidate your warranty and may
cause damage.
1. Insert the USB cable into the port.
2. Connect the USB cable to the charging head,
and then plug the charging head into a standard
outlet.
3. When charging is complete, unplug the charging
head from the outlet and remove the USB cable
from the device.
Caution: Failure to unplug the wall charger before you
remove the battery, can cause damage to the device.
Getting Started
When to Charge the Battery
When the battery is weak and only a few minutes of
operation remain, the device sounds a warning tone.
In this condition, your device conserves its
remaining battery power by dimming the screen.
When the battery level becomes too low, the device
automatically turns off.

For a quick check of your battery level, view
the battery charge indicator located in the
Status Bar of your device's display. A solid color
( ) indicates a full charge.
You can also choose to display a percentage
value. Viewing a percentage value can provide
