I just wanted to share my personal experience when going from a Watch 7 alluminium to a Ultra 2.
I did not have any issues with a regular Watch in terms of battery life since I do not monitor sleep with my Watch. I usually ended my day with 40% battery and put the Watch on charge at night. But wow, its a big difference. Now i charge my Watch to 80% and after two days its around 30-40%, so it should go for 3 days with a full charge no problem. Great to be more flexible around charging!
I also notice the screen is much easier to see in the sun of course because of the 3000 nits display.
Its small things, but the battery life is the most important thing for me, its a game changer. All in all very happy with my switch. It took a little while to get used to the added size and weight going from a 41 mm 7.
I went from a SS S5 that I had for a little over 4 years to an Ultra 2 over the weekend. The battery on the S5 was down to 80% and there were days I had to put it back in the charger around 7 or 8 pm just to finish the day. Anyway, the Ultra 2 is a really nice upgrade with one exception—I don’t love the Ocean band. It’s bulky and feels… cheap. Like it won’t have the longevity of the old Sport bands (for reference, I was still using the band that came with my Series 0 with the S5). Time will tell, I suppose.
