Battery Operation Condition and Recommendation

The battery operating conditions affect the battery life. Usage of the handset,
its configuration, and the operational environment are other significant
factors that affect the battery life.

Deployment Considerations

The handset requires more power to retain connection with the base station with
poor or no radio connection. The battery loses the charge faster when a handset is
in a poor or no signal area for an extended period. We recommend you ensure
good signal in most of the handset usage areas. Place the charging cradle in an
area with good signal to use less power and charge the battery faster. For more
information about the signal strength, see Site Survey Tool section in the Cisco IP
DECT Phone 6800 Series Deployment Guide.

Configuration Settings

The various configuration settings can affect the battery performance. Based on
your needs, you may consider the setting options to optimize the battery usage.
• Ringer Volume and Vibrate Mode
The handset in vibrate mode consumes more power. When you combine
this mode with ringer volume setting, it further increases the power
consumption. The battery life for each charging cycle reduce with an
increase in power consumption.
• Power Save
Power Save settings allow you to configure from 5 seconds to 60 seconds.
The battery life for each charging cycle is better when this setting is low.
We recommend you to use 5 seconds for this setting for maximum battery
life.
• Bluetooth
Bluetooth is supported only on 6825 Handset and 6825 Ruggedized
Handset. The battery requires more power when Bluetooth is enabled,
while searching for devices, and using paired devices.
• In-Call Audio
The wideband calls require two (2) DECT channels and narrowband calls
require one DECT channel for the media between the base station and the
handset. The selection of the wideband or narrowband may not change
the battery life but may have some impact in an average condition and
active call hours.

Handset Battery Charging

The LED indicators on the handset and the charging cradle show the battery
charging status.
An empty battery takes up to 5 hours to charge the battery to 100%. The battery
life and the battery usage environment affects the charging cycle.
