Apple Watch Theater Mode Cuts Heart Rate Checks to 5 Minutes on Series 12 and Ultra 4

Summary
Apple’s updated Theater Mode now spaces heart-rate readings to five-minute intervals on Apple Watch Series 12 and Ultra 4, reducing green LED flashes in dark venues.
The change targets a new hardware behavior: those watches otherwise measure heart rate every five seconds, creating a potential distraction during movies or performances.
Theater Mode still silences alerts and keeps the screen off, and users can override the setting to restore continuous heart-rate monitoring.
