Home > Cisco Wireless IP Phone 7920

Between rechargings of the battery, the 7920 is claimed to deliver two hours of "talk time" and twenty-four hours of "standby time" (which presumably means it is switched on, yet idle) (ComputerWeekly.com Ltd., 2003). Twenty-four hours is a relatively low level of standby time compared to GSM mobile phones, which can have standby times of a week or more. This is presumably due to the greater power requirements of the 802.11 hardware and the protocols lack of power management.
