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。通过降低移动网页应用的能耗，我们不仅能延长设备电池寿命，还能为节能事业做出重要贡献。例如，若仅节省网页应用5%的能耗，我们估算这足以关闭福岛的一座核反应堆。本文针对移动网页应用的节能实验及相关方法进行了全面综述，适用于研究人员及从业者。为实现这一目标，我们开展了系统性文献综述，筛选出44篇主要研究纳入分析。通过对科学论文的映射与分析，本研究贡献如下：(1) 概述移动网页应用的能耗问题；(2) 全面阐述节能实验所采用的方法论；(3) 对不同节能方法进行分类与综合。
