Energy aware computing is as ubiquitous as ubiquitous computing itself. The user experience and up-time of hand-held devices are affected directly by the squander of battery resources. We will focus on embedded systems, e.g., smartphones, or tables, and highlight the most prominent sources of power consumption in application processors. The temperature dependency of the power consumption is also discussed. This implies the importance of thermal models for passively cooled devices, used by DVFS controllers, process schedulers, and thermal management units. Passively cooled devices show substantially different thermal behavior compared to actively cooled devices. Our latest developments on this topic are briefly presented. Furthermore, common energy optimization techniques, both software and hardware based, are discussed. The referenced material covers practical, industrial and academic solutions to the energy optimization problem.
