· By Endurance Wire
Apple today announced the Apple Watch Ultra 4, which features a new S11 chip, a redesigned health sensing system, and a larger battery that Apple says delivers two days of battery life. With improved power efficiency, Ultra 4 offers up to 18 hours of workout tracking with full GPS and heart rate monitoring, or 45 hours in its maximum extended workout mode, according to Apple. The redesigned health sensing system features a larger electrode surface for improved skin contact during ECG readings, photodiodes arranged in a ring to capture light more efficiently, and larger, more power-efficient green LEDs for heart rate tracking.
