Measurements of Power Consumption in Smartphones

Nowadays, Third Generation (3G) mobile phones equipped with powerful hardware are becoming popular and dominating the market of cellular com-munication systems. Features such as music and video players, in-built Global Positioning System (GPS) receivers, navigation maps, Internet con-nectivity and high resolution cameras has converted mobile phones into so called Smartphones. With the increase in applications and services, limita-tions on energy consumption are also increasing. Therefore, it is more im-portant for manufacturers to nd eective means of increasing battery life of mobile phones, as the mobile device itself is energy consuming and longer operational times are demanded by customers. Good energy mangement in mobile phones requires a good understanding of the energy usage in mobile phones. To this end, this thesis report presents the results of power and energy consumption measurements conducted on available Smartphones
