Mobile web browsing has recently surpassed desktop browsing both in term of popularity and traffic. Following its desktop counterpart, the mobile browsers ecosystem has been growing from few browsers (Chrome, Firefox, and Safari) to a plethora of browsers, each with unique characteristics (battery friendly, privacy preserving, lightweight, etc.). In this paper, we introduce a browser benchmarking pipeline for Android browsers encompassing automation, in-depth experimentation, and result analysis. We tested 15 Android browsers, using Cappuccino a novel testing suite we built for third party Android applications. We perform a battery-centric analysis of such browsers and show that: 1) popular browsers tend also to consume the most, 2) adblocking produces significant battery savings (between 20 and 40% depending on the browser), and 3) dark mode offers an extra 10% battery savings on AMOLED screens. We exploit this observation to build AttentionDim, a screen dimming mechanism driven by browser events. Via integration with the Brave browser and 10 volunteers, we show potential battery savings up to 30%, on both devices with AMOLED and LCD screens.

关于手机浏览器的电池消耗

移动网络浏览最近在流行度和流量方面都超过了桌面浏览。继桌面浏览器之后，移动浏览器生态系统已经从少数浏览器（Chrome、Firefox 和 Safari）发展为众多浏览器，每个浏览器都具有独特的特性（电池友好、隐私保护、轻量级等）。在本文中，我们介绍了一个适用于 Android 浏览器的浏览器基准测试管道，包括自动化、深入实验和结果分析。我们使用 Cappuccino 测试了 15 个 Android 浏览器，这是我们为第三方 Android 应用程序构建的新型测试套件。我们对此类浏览器进行了以电池为中心的分析，结果表明：1) 流行的浏览器也往往消耗最多，2) 广告拦截可显着节省电池电量（20% 到 40% 之间，具体取决于浏览器），3) 暗模式在 AMOLED 屏幕上可额外节省 10% 的电池电量。我们利用这一观察来构建 AttentionDim，这是一种由浏览器事件驱动的屏幕调光机制。通过与 Brave 浏览器和 10 名志愿者的集成，我们展示了在配备 AMOLED 和 LCD 屏幕的两种设备上最多可节省 30% 的电池电量。
