A methodology for selecting experiments to measure energy costs in smartphones

Smartphones equipped with latest applications and features are the reality of the modern telecommunication world. Researchers have studied the energy consumption in smartphones while running some network related applications (NRAs) but they have neither fully covered the wide pool of NRAs nor provided a methodology to measure the energy consumption in smartphones. In this paper, we identified the most popular NRAs and configurable parameters which can impact the energy consumption while running these NRAs. We further propose a methodology to measure the energy consumption in smartphones while conducting a feasible set of experiments. We present a measurement bench for measuring the energy consumption in smartphones. We conducted selected experiments on latest smartphones (BB 9700, Nokia E71, HTC Nexus One and HTC HD2) to support our methodology. Our methodology evaluates the impact of configurable parameters and NRAs on energy consumption and provide a base to compare the energy consumption across smartphones.
