Should you buy it?
Buy the Apple Watch Ultra 4 if you have an iPhone and want multiday battery with dive, satellite and 5G features: Apple lists it at $799 (Oct 8, 2026), and it lasted 74 hours in one review test with the always-on display and a daily GPS workout. Apple rates it at 50 hours, or 84 in Low Power Mode, and its new sensor checks heart rate every five seconds. Skip it if you own an Ultra 3, because the 49mm titanium case and screen are unchanged and most upgrades also come on the $399 Series 12. It comes in one size and works only with an iPhone.
iPhone owners who hike, dive or run long and want Apple's longest battery and satellite messaging.
Ultra 3 owners, small wrists, and Android users.
