Battery Life
The main battery has a limited service life. Repeated charging and
discharging of the battery will result in a gradual decrease in the
charging capacity of the battery. If a fully recharged battery operates the
device for a much shorter period than before, this indicates the end of
battery life. When battery life is over, replace the battery with a new one.
The life of the main battery can vary, depending on how the device is used
and ambient temperatures.
Tip: Unlike NiCad and Nickel Metal Hydride batteries, charging the main
LiIon battery with some amount of power remaining hardly reduces the
maximum allowable operating time.
Note: Do not use the device at too high a temperature. The battery life
will become shorter than when used at normal temperatures.
Note: For safe disposal options of your Lithium Ion batteries, contact
your nearest Sprint-authorized service center.
Note: Be sure to dispose of your battery properly. In some areas, the
disposal of batteries in household or business trash may be prohibited.
Battery Operating Time
The main battery allows approximately 2.5 hours of continuous talk
time, approximately seven days of continuous standby time, or
approximately 12 hours of continuous PDA operation time.
Note: The maximum continuous talk time, standby time, and PDA
operation time are affected by backlight settings, service searching,
vibrate mode, game use, and browser use.
Note: The maximum battery operating time varies, depending on how the
device is stored and on ambient temperatures. Charging or using the
battery at low temperatures (less than 0°C/32°F) can cause a significant
reduction in the maximum operating time because of the characteristics
of a Lithium Ion battery. The standard maximum operating time is
restored when placed under room temperature conditions (25°C/77°F).
