Power Save mode
In Power Save mode, the backlight on the screen is not lit when the phone is not in use. The phone remains
in Power Save mode for the scheduled duration or until the user lifts the handset or presses any button. In the
Phone Configuration window on Cisco Unified Communications Manager Administration, configure the
following parameters:
Days Display Not Active
Specifies the days that the backlight remains inactive.

Display on Duration
Indicates the length of time that the backlight is active after the backlight is enabled by the programmed
schedule.
Display Idle Timeout
Defines the period of user inactivity on the phone before the backlight is turned off.
EnergyWise Mode
In addition to Power Save mode, the Cisco Unified IP Phone supports Cisco EnergyWise (Power Save Plus)
mode. When your network contains an EnergyWise (EW) controller (for example, a Cisco switch with the
EnergyWise feature enabled), you can configure these phones to sleep (power down) and wake (power up)
on a schedule to further reduce power consumption.
Set up each phone to enable or disable the EnergyWise settings. If EnergyWise is enabled, configure a sleep
and wake time, as well as other parameters. These parameters are sent to the phone as part of the phone
configuration XML file. In the Phone Configuration window in Cisco Unified Communications Manager
Administration, configure the following parameters:
Enable Power Save Plus
Selects the schedule of days for which the phone powers off.
Phone On Time
Determines when the phone automatically turns on for the days that are selected in the Enable Power
Save Plus field.
Phone Off Time
Determines the time of day that the phone powers down for the days that are selected in the Enable
Power Save Plus field.
Phone Off Idle Timeout
Determines the length of time that the phone must be idle before the phone powers down.
