The S11 will bring some much-needed performance improvements to the Ultra 4 ahead of Apple’s upcoming watchOS 27 release that will include the smarter and more capable Siri AI assistant announced at [Apple’s annual WWDC conference earlier this year](/tech/942416/apple-siri-ai-update-wwdc).\n\nThe Apple Watch Ultra 4 features an improved sensor with upgraded electrodes for better ECG measurements alongside more power-efficient green LEDs allowing for more accurate heart rate measurements all day long and during physical activities. The improved energy efficiency allows the Ultra 4 to take heart rate readings up to 60 times more frequently than previous models at 5-second intervals. Heart rate variability measurements, a metric that provides insights about how your body responds to stress and recovery, can now be taken every five minutes.\n\nThe new model follows the [Apple Watch Ultra 3, which launched last year](/news/770763/apple-watch-ultra-3-awe-dropping-event).
