Circuit and methods for tracking the total amount of time that a host device has spent in its high power "activated" state (and optionally idle and hibernate states) and thereby can estimate the total power consumed by the host device. A value representing this time may be send to a remote device to, for example, accurately determine how much of the energy has been consumed by the host device and how much time is left and/or how many operations can be performed before the host device's battery is exhausted.
