Investigation of the relationship between code change set n-grams and change in energy consumption

Abstract: The amount of software running on mobile devices is constantly growing as consumers and industry purchase more battery powered devices. On the other hand, tools that provide developers with feed- back on how their software changes affect battery life are not widely available. This work employs Green Mining, the study of the rela- tionship between energy consumption and software changesets, and n-gram LLMs to evaluate if source code changeset perplex- ity correlates with change in energy consumption. A correlation be- tween perplexity and change in energy consumption would permit the development of a tool that predicts the impact a code changeset may have on a software applications energy consumption. The case study results show that there is weak to no correlation between cross en- tropy and change in energy consumption. Therefore, future areas of investigation are proposed.
