1. A method for optimizing power in a portable computing device (PCD) comprising: while the PCD is in an off-line state: identifying one or more axes in a coordinate system that impact power consumption of the PCD; identifying at least one axis as a variable this is one of optimized and measured; creating one or more synthetic workloads corresponding to the one or more axes in the coordinate system which impact power consumption of the PCD to simulate various possible operating conditions of the PCD; creating a hypersurface by using the synthetic workloads; placing the PCD into a normal operating state; while the PCD is in the normal operating state: applying one or more actual workloads corresponding to the synthetic workloads to the PCD; executing one or more workload predictors based on the actual workloads; using values from the workload predictors to map on to the hypersurface; and adjusting parameters of the workload predictor based on one or more values from the hypersurface.
