1. A communication system, comprising:
- a communication device configured to run in an active mode and a sleep mode during which a user-specified listening interval is used to power up the communication device from the sleep mode to detect any processing activity that requires the communication device to enter the active mode; and
a memory for storing a power management module for monitoring the communication device activity to directly control entry of the communication device into the sleep mode without requiring external intervention and to adjust the listening interval in response to a predetermined condition to thereby adjust power saving performance for the communication device, where the power management module provides an input/output interface that permits a user to control the user-specified listening interval.

Abstract
A method and system for efficiently managing power consumption in a mobile device controls power consumption with an adjustable sleep period or listening interval that may be user-specified and automatically tuned based on recent detected usage. With an adjustable sleep period, a receiver conserves power by leaving a sleep mode only at predefined and adjustable periods, which may be selected by the user to balance connectivity and power saving and which may be automatically incremented when the device activity is low.

11. An article of manufacture having at least one recordable medium having stored thereon executable instructions and data which, when executed by at least one processing device, cause the at least one processing device to:
-
place a peripheral device in a sleep mode when a threshold level of idleness is detected at the peripheral device without requiring further software intervention; periodically wake up the peripheral device using a wake up interval having a default value; and adjust the wake up interval in response to a predetermined condition comprising entry of a user-specified wakeup interval, in which case the at least one processing device adjusts the wakeup interval to the user-specified wakeup interval. - View Dependent Claims (12, 13, 14, 15, 16)

17. In a wireless communication device, a method for controlling power save operations, comprising:
-
setting a listening interval at a user-specified duration that is different from a default listening interval; placing a communication device in a sleep mode until the listening interval expires, at which time the communication device is powered up to detect if there is any activity for the communication device; monitoring an activity measure for the communication device; and dynamically adjusting the listening interval when a change in the activity measure is detected. - View Dependent Claims (18, 19)
