Mobile devices, such as smart phones and tablets, have become an integral part of our daily life, providing a lot of fancy and powerful applications. To understand and solve the battery drain problem, we design and implement the Bugu service which targets the applications running on mobile devices, analyzes event-power relationship, and provides users an overview of the power behavior of applications. We envision that three groups of people will benefit from the Bugu service. For end users, they know applications' power behavior which in turn helps them to decide which applications to install and run. For application developers, they could understand which events cause such amount of power dissipation and focus on optimizing them. For system developers, the insights provided by the Bugu service will enable them to understand the potential problem of the system so that further optimization can be enhanced.
