Using Your Phone's Battery and
Charger
Warning! Use only Trumpet Mobile-approved or manufacturer-
approved batteries and chargers with your phone. The
failure to use a Trumpet Mobile-approved or
manufacturer-approved battery and charger may increase
the risk that your phone will overheat, catch fire, or
explode, resulting in serious bodily injury, death, or
property damage.
Trumpet Mobile- or manufacturer-approved batteries and
accessories can be found at Partner Stores.
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 3.8 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 sounds an audible alert and then
powers down.
Note: Long backlight settings, searching for service and vibrate
mode affect the battery's talk and standby times.
Tip:
Be sure to watch your phone's battery level indicator and
charge the battery before it runs out of power.
