Energy-Efficient Code by Refactoring

The rising number of mobile devices increase the interest in longer battery durations. To increase battery duration, researchers try to improve e.g. different hardware components, such as processors and GPS for lower energy consumption. Frequently, software optimization possibilities to save energy are forgotten. Hence, an approach is shown to reduce energy consumption of applications by reengineering. Therefor, energy-wasteful code in applications is searched by code analysis and then restructured to optimize their energy consumption. Energy savings are validated by different energy measurements techniques.
