Abstract
Methods and systems for managing thermal load distribution on a portable computing device (“PCD”) include storing on a PCD a plurality of thermal load steering scenarios which identify simulated thermal load conditions for the PCD, corresponding simulated workloads that produced the simulated thermal load conditions, and thermal load steering parameters for steering the simulated thermal load to a predetermined spatial location on the PCD. A scheduled workload for the PCD is monitored to identify a match with one of the thermal load steering scenarios so that the workload may be scheduled according to a thermal load steering parameter. Another method includes initiating a thermal mitigation technique on a PCD and determining a current graphical load being processed by the PCD. A graphics feature associated with the current graphical load is identified. The graphics feature is then disabled while maintaining a frame rate to reduce temperature of the PCD.
