Apple Watch Ultra 4 vs Ultra 3: What's New and Should You Upgrade?

techradar.com — September 9, 2026 at 09:01 PM UTC

Apple unveiled the Apple Watch Ultra 4 at its September 9 event, with the same $799 starting price as the Ultra 3 and availability from September 18. The new model offers key upgrades over its predecessor. The Ultra 4 features a slimmer, wider titanium case, a 48-hour battery life (six hours more than the Ultra 3), and a redesigned Health Sensing System for improved heart rate accuracy. It also introduces a Readiness Score, Health Age, and exclusive Audio Intelligence features like Shazam and Live Rewind. The Ultra 3 retains all its core features, including LTE and satellite connectivity, and will likely receive the redesigned Health app. However, the new Readiness Score and Audio Intelligence appear exclusive to the Ultra 4, making it a compelling upgrade for fitness-focused users.
