NeTS: Small: Collaborative Research: Towards a User Centric Battery Management System for Smartphones


There has been a recent explosion in the number of smartphone applications (apps). As users begin to download and use more and more such apps, they typically find that their smartphone batteries cannot cope with their use. Our goal in this proposal is to analyze the battery drainage behavior of an app with respect to their diverse usage patterns, and provide the user with information on his high-energy apps.

We first seek to develop a fundamental understanding of the factors that affect energy-consumption in apps, with an emphasis on how they cause energy-consumption to differ across usage patterns. Based on this understanding, we propose to design and implement a user-centric battery management system, TIDE (TIDE stands for Tool for IDentifying Energy hungry applications on smartphones). TIDE has two primary goals. First, it seeks to determine and report to the user, which apps on her phone dominate the consumption of the phone's battery. The second objective of TIDE is to incorporate targeted solutions that change the mode of operation for some of the user' s services, so as to trade-off performance for energy efficiency. In other words, it seeks to offer the user the choice of continuing to use a specific set of services at reduced quality or performance, towards conserving her battery.

Towards fulfilling the above goals, we propose the following tasks:

We expect that the proposed work will have an immediate impact in empowering users with an ability to control their battery usage. It will create a public awareness of types of smartphone activities that will result in high battery drainage. The proposed work will also impact education at UCR and UCD in significant ways. New courses on system design and implementation will be introduced. Further, the PIs will undertake outreach efforts where they will visit nearby K-12 schools to inspire students about computer science research. The PIs are committed to fostering diversity and advising women.
