Apple Watch Ultra 2 TEARDOWN confirms modified battery
More: Apple Watch Ultra 2 Review
iFixIt’s teardown video of the Apple Watch ULTRA 2 is linked below and has these three takeaways regarding any new components that might have been secretly added
- the battery is different to the original Ultra and is now rated at 564mAh, which is a 4% increase as reported here a few days ago.
- The Double tap gesture appears to have no new associated hardware outside of the main chip. So it’s a software upgrade and that’s upgrading from software that could already do the same thing. Hmmm.
- there’s obviously the new S9 chip
that’s it
I still think the 4% extra battery life is the most exciting thing about this product (I have one on my wrist at the moment).
is Apple Watch Ultra 2 Accurate? Yes but not always. [Detailed Report, Comparisons]

My favourite kit and nutrition
- Injinji – Runners protect your toes. Avoid discomfort and minor injury. Run more. Run faster. I use them.
- Garmin 90-degree charging adapter — The small adapter that keeps your charging cables tidy. Essential for race day. I use one.
- Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session. I use one.
- Ravemen FR300 — Front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters. I use one.
- Body Glide – The blue anti-chafe stick that all swimmers and many runners use. I use it.
- Maurten — The race nutrition trusted by elite athletes. Gels and drink mixes engineered to be easy on the stomach. I use them.
- Garmin Varia RTL515 — A radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch. I use this model.
- Favero Assioma Pro RS2 — The power-meter pedals most serious cyclists choose. Accurate, easy to move between bikes. I use this model.
- Garmin Forerunner 970 — A serious choice for a pro-grade triathlon watch. I use this.
- Polar H10 — My daily driver for accurate, waking HRV readings.
- Wahoo ELEMNT Roam 3 — The bike computer that has the feature Garmin lacks: usability. I use mine on most rides.

Did you manage to do some running with it? How is the gps accuracy? Same/similar to AWU1?
yes
i have some excellent overall results (I think the best on my standard test). tentatively i would say that the overall excellenace is brought down with tall building and tree cover…a well-worn story!!
I should have gone crazy to buy this watch. I’m unable to see any other reason except purchasing it for smart watch purpose if you have an iphone. Even a Venu 2 is a lot better for sports and general health tracking with 7 days of solid battery life.
Man, the design of Apple Watch series make me sick, really bad.
if you’re buying a smartwatch why even by the ULTRA unless you like the aesthetic?
Because you need a watch to make it through a day and night ????.
I’m with the other guy, no Apple Watch for me until it matches Garmin’s metrics and current battery life.
