device, then from the wall outlet.
You do not need to charge the battery for a specific length of time, and you
can use the device while it is charging. If the battery is completely discharged,
it may take several minutes before the charging indicator appears on the
display or before any calls can be made.
Tip: Disconnect the charger from the wall outlet when the charger is not in
use. A charger that is connected to the outlet consumes power even when it
is not connected to the device.
USB charging
You can use USB charging when a wall outlet is not available. Data can be
transferred while charging the device. The efficiency of USB charging power
varies significantly, and it may take a long time for charging to start and the
device to start functioning.
