An example implementation includes a main SoC comprising main processor(s), an auxiliary processor, and a kernel that executes on the one or more main processor cores. During kernel suspend of the kernel, a power management microcontroller monitors a battery for conditions corresponding to respective wake-on-battery triggers, detects that the monitored conditions correspond to a particular wake-on-battery trigger; and in response, sends, to the auxiliary processor, an interrupt corresponding to a particular wake-on-battery trigger, wherein the interrupt causes the auxiliary processor core to enable the main processor(s) and resume the kernel from kernel suspend. After resuming from kernel suspend, the kernel adds a first kernel resume source event indicating the particular wake-on-battery trigger to a power event queue. A power coordinator background process reads the power event queue and sends data indicating the particular wake-on-battery trigger to one or more client programs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Portable playback device power management","description":"Example techniques related to portable playback device power management.
