Being battery operated, power depletion is a major concern in smartphones design and usage. In particular, it is widely known that wireless communication is a significant source of energy consumption. Hence, having a better understanding of the way wireless communication impacts battery drain and the tradeoff between bandwidth usage and power consumption is important.
In this talk, I will describe a combined power and throughput performance study of WiFi and Bluetooth usage in smartphones. The study reveals several interesting phenomena and tradeoffs. The conclusions from this study suggest preferred usage patterns, as well as operative suggestions for researchers and smartphone developers.
