# PCMag Reviews Apple Watch Ultra 4: Rugged Smartwatch Features 74-Hour Battery Life and S11 Chip Canonical page: https://savlume.com/items/fpgecyzq5w82g7844kt5d9ley Publisher: Savlume Published on Savlume: 2026-09-17T12:00:00.000Z Content updated: 2026-10-13T20:18:27.174Z Source publication time: 2026-09-17T12:00:00.000Z Offer status: Unverified In PCMag's testing, the $799 Apple Watch Ultra 4 delivered 74 hours of real-world battery life alongside upgraded five-second heart-rate sampling and responsive Siri AI via Apple's S11 processor. Reviewer Andrew Gebhart found the 49mm titanium smartwatch matched chest-strap accuracy during intense workouts and handled weekend trips without a charger. PCMag recommends the device for outdoor athletes and owners of older Ultra models, while noting its large footprint and high price point remain overkill for typical iPhone users. ## Media review PCMag rates the Apple Watch Ultra 4 4.0, calling it an endurance-focused upgrade with a 74-hour tested battery life, while saying its $799 price makes it a specialized choice rather than the best fit for most iPhone users.
