A hardware and software Web-based environment for Energy Consumption analysis in mobile devices

In recent times, the number of mobile Android devices has been growing exponentially not only in the expanding popularity of low-cost mobile devices but also for the great number of functionalities and applications. This new range of features has highlighted the need for greater capacity in mobile batteries to provide an extended time of use. Several studies have been done to minimize the impact on the uncontrolled growth of applications, as well as analyze the suitable hardware configuration for a range of applications. In this sense, the objective of this work is to provide a Web-based environment which helps the designer to characterize mobile devices through automated testing and multiple devices simultaneously. The Web environment allows the designer to make assessments on the mobile device, remotely, without the need for measurement environment available. The use of multiple devices allows the designer to perform in different parallel measurements simultaneously. As the case study, an analysis involving video streaming, CPU processor load, and CPU fixed-frequency algorithms versus dynamic frequency scaling techniques were performed for two types of Android smartphones.
