Extend APIs to collect subsystem low power statistics. Many subsystems (e.g.wifi) could be living on an independent power island (sourced from VBatt directly) and might even have their own dedicated XTAL to source their clocks. Since these SOCs are capable of autonomously operating (while the platform is in one of the sleep states), they are still drawing power from the VBatt. Hence it is critical to understand the (SOC) level low power statistics as well when the battery level changes and be able to find any correlation in event of unexpected battery drain.
