Experience

In the past decade, numerous efforts, from both academia and industry, have been made to make batteries in mobile devices last longer on a single charge. Our own research identified a new class of software bugs called energy bugs [1-4] that cause mobile software to quickly drain battery. We built and released numerous tools to detect and mitigate these bugs [2,4,5]. We also suggested energy optimizations in the OS; for instance, OS can suppress activities of background apps that are not being opened by the user [6].
