Abstract

A method for transitioning power states in a device includes designating a first reduced power state as a target power state. A first expected residency for the target power state is determined based on a counting of activity requests associated with the device. The device is transitioned to the target power state responsive to the expected residency satisfying a first predetermined threshold.
