Yunxin Liu, PhD

Power consumption is a paramount concern in battery-powered mobile devices such as smartphones and tablet computers. With powerful hardware and rich applications, modern mobile devices are becoming increasingly power hungry, but the power supply of batteries is very limited. As a result, it is desirable to better manage the power consumption of mobile devices. This tutorial will give in-depth discussions on two key aspects of power management of mobile devices: power modeling and power optimization. The former is to understand how the energy is consumed and the latter is to use the energy efficiently. A broad view of the state of the art will be covered and the intended audiences are the students and researchers who are interested in energy efficiency in mobile devices.


Yunxin Liu is a Lead Researcher at Microsoft Research Asia. He received his Ph.D. from Shanghai Jiao Tong University through the SJTU-MSRA joint PhD program. His research interests are mobile systems and networking, with recent focus on power management, security and privacy, and human sensing. His research work has been published in top conferences and journals, transferred into multiple Microsoft products such as Visual Studio, XBOX XDK, and Windows Phone, and featured in news media including ABC News, The Register, NetworkWorld, and many others. He is a member of the IEEE and the ACM. For more information, see
