Contemporary mobile devices are equipped with multiple network interfaces with diverse characteristics. Although the Wi-Fi interface bestows commendable throughput and data transfer efficiency, it is least power efficient in the idle state and causes highest energy overhead when scanning for networks. In this paper we present a data driven approach to alleviate this issue, focusing on Wi-Fi usage by the user's perspective. We model the Wi-Fi usage of mobile users based on their past usage to predict usage requirements. This allows intelligently switching on the Wi-Fi interface only if the user context demands. Thus, it reduces long periods of time being in the idle state and significantly le..
