Abstract
During operation, an electronic device monitors data associated with different power states received from another electronic device via an interface circuit. 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.
