Key Features of Apple Watch Ultra 4

Up to 50 Hours of Battery Life

Apple rates normal use at up to 50 hours, and a 15-minute fast charge gives up to 18 hours. A new Max Extended Mode stretches GPS workout recording to 45 hours without reducing GPS or heart rate data, which is ideal for ultramarathons and long hikes.

S11 Chip and Health Sensing System

The S11 chip powers new Audio Intelligence features such as Sound Recognition and Live Rewind. The redesigned sensor package uses a larger electrode surface for better ECG contact and photodiodes arranged in a ring for more efficient light capture, along with larger green LEDs for heart rate.

49mm Titanium Case with Sapphire Display

The 100 percent recycled Grade 5 titanium case pairs with a flat sapphire front and a ceramic back. The 1.9-inch OLED display reaches up to 3000 nits, resolution is 514 x 422 pixels at 346 ppi, and the watch is rated IP6X dust resistant and MIL-STD-810 certified.

Action Button and Improved GPS

The customizable Action button gives instant access to workouts, waypoints or your favourite shortcut, even with gloves on. Better GPS helps with features like Race Route during runs.

New Bands and a Hermès Edition

Apple has introduced new Trail Loop colors (Dark Umber, Sand, Burgundy), Alpine Loop colors (Desert, Dark Olive, Burgundy) and a translucent silicone Ocean Band (Translucent Gray, Kelp, Black).

Readiness and Recovery Insights

Heart rate is measured every five seconds through the day, with more frequent heart rate variability readings feeding the readiness score and sleep insights.
