Lol yeah, the “just play silent audio to keep a PWA alive” trick technically works because mobile OS schedulers whitelist active media sessions from background throttling. It basically hijacks the system’s media lifecycle to prevent service workers from being garbage-collected. It’s clever, but it’s also a battery vampire, surfaces phantom media controls, and gets flagged in App Review if you ever wrap it natively. Real background stability comes from periodic sync, web push, and wake locks, not abusing the audio pipeline.

Educate yourselves.
