The Apple Watch Ultra 4 stands as the pinnacle of Apple's smartwatch offerings, delivering an extended battery life and a more insightful experience for health and fitness enthusiasts. While it may not present a compelling reason for immediate upgrade for existing Ultra 3 owners, its advancements make it a significant contender in the premium smartwatch market.
Detailed Examination of the Apple Watch Ultra 4
Unveiled on October 5, 2026, the Apple Watch Ultra 4 continues Apple's tradition of innovation in wearable technology. The device, priced at £749 in the UK and $799 in the USA, maintains the robust 49mm grade 5 titanium casing seen in earlier Ultra models. Despite its familiar exterior, a subtle increase in weight is barely noticeable in daily wear. The watch boasts a 1.9-inch screen, an IPX6 rating, and 5ATM waterproofing, making it suitable for various demanding activities.
A notable enhancement is the redesigned health sensing system located on the watch's underside. This system features an expanded electrode surface area and larger LEDs, enabling more frequent and potentially more accurate heart rate monitoring and temperature readings. This forms the backbone for new features such as 'Readiness scores' and 'daytime/nighttime Vitals views,' which provide a comprehensive overview of the user's physical state and recovery needs. The heart rate tracking during exercise, while generally satisfactory, showed slight underreporting of maximum heart rates compared to professional chest strap monitors.
Powered by the new S11 chip and running watchOS 27, the Ultra 4 introduces several software advancements. A more intelligent Siri now offers improved conversational capabilities, capable of recalling past interactions and providing more relevant responses to complex queries. New 'Audio Intelligence' features, leveraging the S11 chip and the watch's microphone, include automatic sound recognition and a quicker Shazam integration. Upcoming features like 'Live Rewind' and 'Siri Recap' promise to revolutionize how users interact with audio, though Apple emphasizes stringent privacy protocols for these features.
Battery life receives a welcome boost, extending to over two days of typical use—a significant improvement from the Ultra 2's 42 hours. In low-power tracking mode, the device can last up to an impressive 84 hours. During intense activities, such as a half-marathon, the battery depletion was minimal, showcasing its endurance for prolonged use. Fast charging capabilities ensure that the watch can reach 80% capacity in just 45 minutes, or provide enough power for a night's sleep tracking with a mere 5-minute charge.
Reflections on the Apple Watch Ultra 4's Place in the Market
The Apple Watch Ultra 4 represents a thoughtful evolution rather than a revolutionary leap. For those new to the Ultra series or upgrading from older models, its blend of enhanced battery life, sophisticated health tracking, and intelligent software makes it a highly attractive option. The inclusion of readiness scores and advanced vital sign monitoring positions it as a strong competitor in the health and fitness wearable segment. However, for current Ultra 3 owners, the incremental updates, particularly the unchanged design and delayed availability of some advanced software features, might not warrant an immediate upgrade. Ultimately, the Ultra 4 solidifies Apple's position at the forefront of the smartwatch industry, offering a premium experience tailored for active and health-conscious individuals, albeit at a premium price point.
