Using the monitored data, the electronic device calculates a time duration that the other electronic device is in an active operating mode. Moreover, the electronic device determines power states of the other electronic device based on the calculated time duration and/or a time duration between times when data is received. Next, the electronic device calculates the power-consumption history of the other electronic device based on the determined power states and at least a model of power consumption in different power states of the other electronic device. By calculating the power-consumption history of the other electronic device, the electronic device may significantly improve the accuracy of a power-usage model for the other electronic device. ## Claims ### Claim 1 A method, performed by an electronic device, for tracking power states of a mouse operatively coupled to the electronic device, the method comprising: receiving, from the mouse, electromagnetic signals representing episodic bursts of data that describe motion of the mouse, wherein the electromagnetic signals representing the episodic bursts of data that describe the motion of the mouse are received over a wireless interface;
