With ‘Low Power Mode’ enabled, battery longevity extends to 84 hours. Athletes will benefit from 45 hours of ‘Max Extended Workout Tracking’ and 18 hours of standard tracking.
The retail launch date for the highly anticipated Apple Watch Ultra 4 has been officially set for September 18.
Apple Watch Ultra 4: Key Specs
Apple has replaced the older S10 silicon with the brand-new S11 chip. This processor handles specialized features, such as Siri AI and audio intelligence, entirely on-device.
Since it does not rely on cloud processing, your voice data remains completely secure and private.
The Apple Watch Ultra 4 features completely redesigned optical and electrical sensors. An energy-efficient green LED measures your heart rate every 5 seconds and calculates Heart Rate Variability (HRV) every 5 minutes.
This wearable device uses this high-frequency data to generate a daily “Readiness Advice” score. Consequently, you receive clear guidance regarding your physical capacity for training or recovery on any given day.
The Watch Ultra 4’s specifications highlight features such as precise dual-frequency GPS, Fall Detection, Crash Detection, a siren, and Emergency SOS. You can access emergency assistance without carrying an iPhone.
Upgrading from the Ultra 3 is undoubtedly worthwhile, thanks to the S11 chip’s AI capabilities and significant battery improvements. The feature upgrades in the Apple Watch Ultra 4 transform it into a standalone computing powerhouse.
