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’ve been using the Ultra 3 for about a week now, mainly for running (1–2 hours a day, roughly 10h/week, 120km/week) plus strength training or yoga for about an hour daily. I’m very routine-driven: I work from home, never travel much, always home by 6PM, runs in the morning, workouts in the afternoo

So I went down a rabbit hole last night because I was bored and started wondering: “How much faster is my Apple Watch Ultra 3 compared to my old iPhone 4s?”

Here’s what I found:

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

Ok then it's definitely the App + your battery health. If you do long hikes very regularly, I highly suggest you take a look at Apple Watch Ultra. With a new battery for your AW7, you'll get about 2.5-3 more hours of battery life when hiking. (With AWU, you'll get probably 20-30h of continuous hikin

Need a new watch upgrade from my 2019 Apple Watch S5 with 75% battery health. It dies 3-4 hours into every hike with Alltrails or my activity tracker running. I hike a good amount (currently checking off the New Hampshire 4000 footers and T25), but sometimes can be out there for 10-12 hour days and

I Just upgraded my setup and honestly couldn’t be happier!

Went from iPhone 7 -> 12 Pro -> now 17 Pro, and from Apple Watch 6 -> Garmin Epix Pro 2 to the Apple Watch Ultra 3.

Nice upgrade on both phone and watch - better battery, brighter screen, faster overall. Ultra 3 already feels solid for ev

My Apple Watch Ultra is nearing 2 years of daily use and the battery is still at 96% health. Looks like I’ll be able to wait for the AWU4 next year

8 days is absolutely outstanding with LTE and gps enabled
