Regular works on energy efficiency strategies for wireless communications are based on classical energy models that account for the wireless card only. Nevertheless, there is a non-negligible energy toll called "cross-factor" that encompasses the energy drained while a frame crosses the network stack of an OS. This paper addresses the challenge of deepen into the roots of the cross-factor, deseed its components and analyse its causes. Energy issues are critical for IoT devices. Thus, this paper conceives and validates a new comprehensive framework that enables us to measure a wide range of wireless devices, as well as multiple devices synchronously. We also present a rigorous methodology to perform whole-device energy measurements in laptops, a more generic and suitable device to perform energy debugging. Finally, and using this framework, we provide a collection of measurements and insights that deepens our understanding of the cross-factor.
