9to5Mac • • technology
Key Points:
- The Apple Watch Series 12 and Ultra 4 feature a new Health Sensing System that measures heart rate every five seconds, a significant improvement from the previous five-minute interval.
- The watches include a new Theater Mode that reduces heart rate measurement frequency back to every five minutes to prevent the green light from being noticeable in dark environments and to save battery life.
- Users can override this setting in Theater Mode by enabling “Allow Continuous Measurements” in the watch's Heart settings to maintain frequent heart rate monitoring.
- Sleep Mode also defaults to five-minute heart rate intervals to conserve battery and because less frequent monitoring is sufficient during sleep, though users currently cannot adjust this setting like in Theater Mode.
- The Apple Watch Series 12 and Ultra 4 are now available, offering improved health tracking with customizable settings for different usage scenarios.
