Energy drain in mobile devices is well recognized to be a serious problem. Most

mobile operating systems provide facilities to mitigate energy drain, but

they are usually heavy handed and often require shutting down an offending

application or uninstalling it. In this paper, we describe an alternative

that controls the behavior of an energy hungry application rather than kill it.

Our system offers a finer-grained approach to energy drain and is cognizant

of specific application energy characteristics as well as interactions

amongst multiple applications that can affect energy drain in

unexpected ways. Using our system, we believe

users can avoid the annoyance of sudden and unexpected battery loss,

particularly when operating in standby mode.

Our system, called E-Loupe, consists of components running on each

device as well as in a centralized data center. E-Loupe gathers

per-device data, analyzes this data, and implements energy sandboxing in the device kernel to control how often an energy hungry application is run and what resources it is allowed to

consume. Our experimental results on data from over 73,000 users shows

that we can identify the cause of more than 85% of the energy spikes,

and upper bound the energy drain in nearly all of these cases.
