Apple Watch Ultra 4 review: Another triumph
The Apple Watch Ultra 4 retains its crown for another year, with the addition of the long-requested Readiness score
The Apple Watch Ultra 4 is a solid smartwatch that builds upon its predecessor's strengths. The 49mm titanium build, bright display, and customizable Action Button remain unchanged, while the new S11 chip keeps the device feeling responsive and watchOS 27 runs smoothly. The most notable upgrade is the battery life, which Apple claims can last up to 50 hours with normal use.
In practice, the reviewer managed to use the watch for two full days with the Always-On display and sleep tracking enabled. Faster charging, with a 30% charge in just 15 to 20 minutes, is another welcome addition. Health and fitness tracking also receive a boost, with the new Health Sensing System improving measurements and the Readiness Score providing a useful snapshot of the day's preparedness.
Siri AI brings more intelligence to the watch, with features like Shazam and Sound Recognition. However, the Ultra 4's design remains largely the same, which might not be enough to justify an immediate upgrade for Ultra 3 owners. The watch costs $799 / £749 / AU$1,349 and is available in Natural Titanium or Black Titanium finishes, both with Wi-Fi and cellular connectivity.
