Modeling Video Playback Power Consumption on Mobile Devices
Abstract
Advancements in mobile hardware and streaming technologies enable high-quality video streaming for mobile users, but this comes at a cost: a boost in power consumption. Despite detailed studies on power consumption during acquisition, existing studies fall short of considering recent technologies and, hence, of accurately capturing video playback power consumption. This paper presents a novel method to model mobile video playback power consumption. First, we identify the major components contributing to power consumption during video playback on mobile devices. Then, we develop models for each component to estimate their power consumption. Our experimental results show that our combined model estimates power consumption with 91% mean accuracy. Furthermore, our model maintains its high accuracy on an unseen device, achieving 88% mean accuracy despite the hardware and screen heterogeneity.
