Important: Battery talk and standby times are estimates
only and depend on signal strength, network conditions,
features used, battery age and condition, temperatures to
which battery is exposed, use in digital mode, and many
other factors. The amount of time a device is used for calls
will affect its standby time. Likewise, the amount of time
that device is turned on and in the standby mode will affect
its talk time.
