Abstract: Understanding the energy implications of software design choices is an ongoing research challenge, especially when working with mobile devices that are constrained by limited battery life. In this talk, approaches will be presented supporting software developers to better comprehend the energy implications of software design choices. System API Utilization Profiles (uAPI) are proposed which are based on the general assumption that the actual energy consumption of a library is directly tied to its utilization of the underlying System API. A case study will illustrate the proposed approach. In the second part of the talk, the need for techniques and tools will be argued that will allow end users to better understand the energy consumption of their mobile devices. The first goal is to create awareness, the second goal is to motivate users to change their behaviour towards a more energy efficient use of resources.
