Analysis of the energy consumption of JavaScript based mobile web applications

Abstract

JavaScript is the dominant language of modern web applications. In this research, we have investigated the battery-consumption of JavaScript applications running on mobile phones. In our empirical study, we developed and analysed eight implementations of the same application using different Java-Script libraries. The results show that there are significant differences between different implementations. There is no single factor explaining the performance differences. Furthermore, the performance of different libraries is strongly affected by the communication technology (3G or WLAN). The long latencies that 3G introduces suggest that increasing the parallel execution of server queries has potential for energy and speed improvements. © Springer-Verlag Berlin Heidelberg 2010.
