Battery Capacity This device is equipped with a Lithium Ion (Li-Ion) battery. You can recharge the battery before it is fully drained. The battery provides up to 6.0 hours of talk time. At 3% of charge capacity, there are only a few minutes of talk time left, the device sounds an audible alert, displays a critical charge icon ( ), and then turns off. Note: Long backlight settings, searching for service, vibrate mode, browser use, and other variables may reduce the battery's talk and standby times. Extending Your Battery Life Watch your device's battery level indicator and charge the battery before it runs out of power. Active applications, light levels, Bluetooth usage, and GPS functionality all act to drain your battery. The following is a list of helpful tips that can help conserve your battery power: • Reduce the backlight time. • Turn off Bluetooth when not in use. • Check the Running Services and close any unnecessary applications. • Do not wait until your battery is completely depleted before charging the device. Repeating this process of a complete discharge and recharge can over time reduce the storage capacity of any battery.
