PCMag Reviews Apple Watch Ultra 4: Rugged Smartwatch Features 74-Hour Battery Life and S11 Chip
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.
