Using the Battery
Battery Capacity
your phone is equipped with a Lithium Ion (LiIon) battery. It
allows you to recharge your battery before it is fully drained.
The battery provides up to 3.8 hours of continuous digital talk
time (up to one hour in analog) or up to eight days of
continuous digital standby time (up to 15 hours in analog).
The Empty Battery Icon
Approximately five minutes before the battery charge level gets
too low to operate the phone, the battery sensor will let you
know by blinking an empty battery icon (
), sounding an
audible alert and displaying a warning message. If you
continue to operate the phone without charging, the phone
will turn off automatically (after a three to five minute delay).
If this happens, your call will end. If you plug into a charging
device, you can continue your call. Be sure to monitor the
battery strength icon and make sure your battery is adequately
charged.
