Application performance demands on a modern mobile device are driven by sustained performance workloads, such as 3D games, Virtual and Augmented Reality. Mobile System-on-Chips have corresponding increases in performance through both architectural changes and frequency of operation increases; which has resulted in the peak power consumption exceeding the sustainable thermal envelope defined by device skin temperature requirements.

Through experimentation with a modern smartphone platform using sequences from real-world applications, we demonstrate in this paper that Frequency Capping can have a significant effect on the performance of interactive applications, increasing the number of frame rate defects by up to 146%. We propose Task Utilization Scaling, a new lever for thermal throttling, which scales performance for critical interactive periods by the same factor as non-critical periods.
