ABSTRACT
We present an experimental study of how storage techniques impact energy consumption in smartphones. We design and implement a system that tracks I/O activities of smartphones in real-time and dynamically changes storage configuration by matching I/O patterns in order to reduce energy consumption. Our system is evaluated on the 20 most popular applications from Android Market, and our results show that the optimal configurations save from 21% to 52% of battery life. We believe that they highlight a new and interesting direction in which the topic of smartphone energy consumption can be further evaluated and expanded upon.

Storage-aware smartphone energy savings
UbiComp '13: Proceedings of the 2013 ACM international joint conference on Pervasive and ubiquitous computingIn this paper, to our best knowledge, we are first to provide an experimental study on how storage techniques affect power levels in smartphones and introduce energy-efficient approaches to reduce energy consumption. We evaluate power degradation at ...
Smartphone Energy Drain in the Wild: Analysis and Implications
SIGMETRICS '15: Proceedings of the 2015 ACM SIGMETRICS International Conference on Measurement and Modeling of Computer SystemsThe limited battery life of modern smartphones remains a leading factor adversely affecting the mobile experience of millions of smartphone users. In order to extend battery life, it is critical to understand where and how is energy drain happening on ...
Storage on your smartphone uses more energy than you think
HotStorage'17: Proceedings of the 9th USENIX Conference on Hot Topics in Storage and File SystemsEnergy consumption is a key concern for mobile devices. Prior research has focused on the screen and the network as the major sources of energy consumption. Through carefully designed measurement-based experiments, we show that for certain storage-...
