    Abstract

    Background activities on mobile devices can cause signifi-cant battery drain with little visibility or recourse to the user.They can range from useful but sometimes overly aggressive tasks, such as polling formessages or updates from sensors and online services, to outright bugs that cause resources to be held unnecessarily. In this paper we instrument theAndroid OS to characterize background activities that prevent the device from sleeping.We present Tamer, an OS mechanism that interposes on events and signals that cause task wakeups, and allows for their detailedmonitoring, filtering, and rate-limiting.We demonstrate how Tamer can help reduce battery drain in scenarios involving popular Android apps with background tasks.We also show how Tamer can mitigate the effects of well-known energy bugs while maintaining most of the apps' functionality. Finally,we elaborate on howdevelopers and users can devise their own application-control policies for Tamer to maximize battery lifetime.
