1. A method for managing thermal energy generation in a portable computing device (“PCD”), the method comprising: determining that a power frequency associated with a processing component positioned within the PCD is substantially zero, wherein current remaining on a power rail associated with the processing component may correspond to a presence of a leakage current; measuring the leakage current on the power rail associated with the processing component; based on the measured leakage current, determining a thermal status of the processing component; and based on the thermal status of the processing component, evaluating thermal management policies associated with the processing component.
