One of the serious challenges facing smartphones and other portable devices is battery life. We aim at improving the energy efficiency of multimedia applications for improved battery life while maintaining an acceptable level of user experience. In this paper, we design a stochastic processing technique for JPEG to limit its energy consumption particularly on mobile devices. This is a first step towards improving the energy efficiency for MPEG, since video streaming and conferencing applications are some of the most energy-consuming applications. We demonstrate the feasibility of using stochastic processing for multimedia encoders and analyze the resulting energy savings.
