Watch Ultra 3

I came from the Apple Watch Ultra 1, and its battery was already down to 84%. During my second-to-last marathon, the battery actually died mid-race, and on my last marathon I had to turn off AOD — even then, the battery was down to just 55% by the end.

With the Ultra 3, after a ~3:40 marathon (it w

I had it in Low Power Mode, starting at 85% and ending at 70%. Pretty happy with that! Total distance was almost dead on with my bike computer. At that rate, it would last about 22 hours, which is awesome for me as I am planning on running a bunch of ultras this year.

I finally bought the Apple Watch Ultra 3 today. Super excited to try it out! Looks amazing and feels premium. Anyone else here got it too? What do you think so far?

Last Sunday I did a 3h20m ride with AWU3 and was impressed with the battery life. Today it was time to take WorkOutDoors out into the trails and see how the watch fared.

I’m quite impressed, actually! The watch used 18% of its charge in 2h10m active time with WOD and AOD. The last 9 miles were with

Has anyone used an Apple Watch Ultra (3 or older) as their daily carry instead of an iPhone? Any experiences or tips to make the transition more seamless?

I have struggled along with the Mudita Kompakt but realized I need something smart-ish for work apps and calendars. I feel like the Ultra 3 may

It's there and I think it's great, the U3 in nature! I previously had a first generation stainless steel one with a Milanese bracelet, which still fits :-)

Apple Watch Ultra 3 acquired. A leap from the Series 8. Massive in size (and on my wrist), massive in performance.

My first Apple Watch Ultra 3 — a significant upgrade from my previous Apple Watch Series 1 and Series 3 models.
