Abstract: Various embodiments of methods and systems for optimizing processing performance in a multi-functional portable computing device (“PCD”) are disclosed. Depending on how the PCD is being used, the temperature limit associated with the touch temperature of the PCD may be variable. As such, a preset and fixed touch temperature limit based on a “worst use case” scenario can unnecessarily limit the quality of service (“QoS”) provided to a user under different use case scenarios. Accordingly, embodiments of the systems and methods define and recognize different device definitions for the PCD which are each associated with certain use cases and each dictate different temperature thresholds or limits subject to which the PCD may run.

Abstract: Various embodiments of methods and systems for idle state optimization in a portable computing device (“PCD”) are disclosed. An exemplary method includes comparing an aggregate power consumption level for all processing cores in the PCD to a power budget and, if there is available headroom in the power budget, transitioning cores operating in a first idle state to a different idle state. In doing so, the latency value associated with bringing the transitioned cores out of an idle state and into an active state, should the need arise, may be reduced. The result is that user experience and QoS may be improved as an otherwise idle core in an idle state with a long latency time may be better positioned to quickly transition to an active state and process a workload.
