摘要

在本文中,我们报告了我们6年来开发Eagle测试仪(简称eTester)的经验-一种移动电池损耗测试和诊断工具。我们展示了eTester是如何从一个“学术”原型发展成为移动行业可用的全自动工具的。我们首先展示了我们最初的研究原型的设计,并讨论了一个可用的电池消耗测试和诊断工具的8个关键要求,这些工具是从Android生态系统中一些最流行的软件供应商那里收集的。这些要求提出了有趣的科学和工程挑战,例如如何在不需要先验功率建模的情况下准确估计电池消耗,如何在未修改的设备上工作,以及如何自动监控代码演变以生成具有可操作见解的高保真电池峰值警报。这些需求推动了eTester设计的彻底改革,并创造了一种新的电池损耗测试方法。我们展示了重新设计的eTester如何在一些拥有数亿用户的最受欢迎的安卓应用程序(如Netflix和CNN)中毫不费力地发现电池漏洞。我们将eTester开源,以鼓励在电池诊断方面的进一步研究,并授权开发人员编写电池高效的移动软件。

Experience: developing a usable battery drain testing and diagnostic tool for the mobile industry
In this paper, we report on our 6-year experience developing Eagle Tester (eTester for short) - a mobile battery drain testing and diagnostic tool. We show how eTester evolved from an "academic" prototype to a fully automated tool usable by the mobile industry. We first present the design of our initial research prototype and discuss 8 key requirements for a usable battery drain testing and diagnostic tool gathered from some of the most popular software vendors in the Android ecosystem. These requirements posed interesting scientific and engineering challenges such as how to accurately estimate battery drain without requiring a priori power modeling, work on unmodified devices, and automatically monitor code evolution to generate high-fidelity battery spike alerts with actionable insights. These requirements motivated a complete overhaul of the eTester design and led to the creation of a novel battery drain testing methodology. We show how the redesigned eTester was used to effortlessly find battery bugs in some of the most popular Android apps with hundreds of millions of users, such as Netflix and CNN. We are open-sourcing eTester to encourage further research in battery diagnosis and to empower developers to write battery-efficient mobile software.
