Making web applications more energy efficient for OLED smartphones
A smartphone's display is one of its most energy consuming components. Modern smartphones use OLED displays that consume more energy when displaying light colors as op posed to dark colors. This is problematic as many popular mobile web applications use large light colored backgrounds. To address this problem we developed an approach for auto matically rewriting web applications so that they generate more energy efficient web pages. Our approach is based on program analysis of the structure of the web application im plementation. In the evaluation of our approach we show that it can achieve a 40% reduction in display power con sumption. A user study indicates that the transformed web pages are acceptable to users with over 60% choosing to use the transformed pages for normal usage.
