In 2022, over half of the web traffic was accessed through mobile devices. By reducing the energy consumption of mobile web apps, we can not only extend the battery life of our devices, but also make a significant contribution to energy conservation efforts. For example, if we could save only 5% of the energy used by web apps, we estimate that it would be enough to shut down one of the nuclear reactors in Fukushima. This paper presents a comprehensive overview of energy-saving experiments and related approaches for mobile web apps, relevant for researchers and practitioners. To achieve this objective, we conducted a systematic literature review and identified 44 primary studies for inclusion. Through the mapping and analysis of scientific papers, this work contributes: (1) an overview of the energy-draining aspects of mobile web apps, (2) a comprehensive description of the methodology used for the energy-saving experiments, and (3) a categorization and synthesis of various energy-saving approaches.

翻译：2022年，超过一半的网络流量通过移动设备访问。通过降低移动端Web应用的能耗，我们不仅可以延长设备的电池续航时间，还能为节能努力做出重要贡献。例如，如果我们能仅节省Web应用所用能源的5%，我们估计这足以关闭福岛的一座核反应堆。本文全面概述了移动端Web应用的节能实验及相关方法，适用于研究人员和从业者。为实现这一目标，我们进行了系统的文献综述，识别并纳入了44项主要研究。通过对科学论文的映射和分析，本研究贡献了：（1）移动端Web应用耗能方面的概述，（2）节能实验所用方法的全面描述，以及（3）各种节能方法的分类与综合。
