Providing runtime power profile tuning based on eye state in processor-based Extended Reality (XR) devices is disclosed herein. In this regard, in some exemplary aspects, a processor of a processor-based XR device is configured to apply a default power profile, and detect, using an eye blink detection circuit, an eye close event of a user of the processor-based XR device. In response to detecting the eye close event, the processor selects a test power profile from a plurality of power profiles and applies the test power profile. The processor then measures an operating characteristic of the processor-based XR device and compares the operating characteristic with a corresponding reference range. Based on the comparing, the processor updates one or more power profiles of the plurality of power profiles.

An apparatus comprises a first printed circuit board (PCB) supporting a master subsystem including a master power management integrated circuit (PMIC) coupled to a master processor via a first local interface. The apparatus also comprises a second PCB supporting a slave subsystem including a slave PMIC coupled to a slave processor via a second local interface. The apparatus further comprises a first bi-directional control interface coupling the master processor to the master PMIC and to the slave PMIC. The first bi-directional control interface comprises at least one trace overloaded to carry multiple PMIC functions.
