In this paper, the authors investigate the correlations between the energy consumption of Android devices and the presence of threats (e.g. battery-drain attacks). In particular, this paper proposes a model for the energy consumption of single hardware components of a mobile device during normal usage and under attack. The model has been implemented in a kernel module and used to build up an energetic signature of both legal and malicious behaviors of Wi-Fi hardware component in different Android devices. Such activity allows the users to build a tentative database of signatures that can be used to detect attacks by means of the actual energy consumption of a mobile device.
