Optimising Energy Management of Mobile Computing Devices

Archived September 2011, Revised March 2012


Mobile computing devices are becoming ubiquitous and the applications they run are demanding greater processing and storage capabilities. Managing the power consumption and battery life of these devices is increasingly difficult but some careful choices made in the software architecture stack can optimise power utilisation while still maintaining needed services on the architecture. We describe the hardware blocks in a modern mobile device and measure their power requirements. We discuss some power management strategies and present results showing how some quite dramatic energy savings are possible on a typical modern mobile device running Android and Linux. We discuss the implications for future mobile computing device architectures.

Keywords: device architecture; power consumption; battery life; mobile devices.
