What's rumored so far
Apple Watch Ultra 4 shares the Series 12's new S11 chip and sensor array, in the same rugged case design as the Ultra 3 — no visible redesign this generation. The standout change is battery life: up to 50 hours of average use, or 84 hours in Low Power Mode, a real jump from the Ultra 3. No score yet.
