What was the battery health on the Series 2 before you switched?
It didn’t show battery health on that version, unfortunately.
Didn’t know that! Thanks for the info.
@Case
Where do you find battery health settings?
On your watch: Settings → Battery → Battery Health → scroll down for the percentage.
Wow.
Big improvement 
.
Thinking about making the jump from Series 2 to Series 9.
This reminds me of that sad cat meme

Did the same upgrade last week!

That background on the watch face is cool .
It’s amazing that your old watch lasted 8 years. You’re going to love the new one for sure!
Another Series 2 upgrader! I switched last weekend to the Ultra 2. The performance difference is night and day.
I miss the design of the Series 0-3. They had the best look and size. I’d love to have that with the latest health features.
I used a Series 2 until last year, but the battery life was rough. Went for a Series 7 and haven’t looked back.
Did you ever change the battery on your Series 2?
Congrats! That’s a big upgrade, you’ll feel the difference right away.
I never realized how small the Series 2 was until I saw it next to my Series 5.
Does the cat look impressed?

I upgraded from my Series 2 last week too. The touch screen was no longer working, and the screen was coming loose. The new one feels like a massive leap forward!
The glass was better on the older ones. My Series 10 already has two scratches, and I’ve only had it a month.
Old watches age like fine wine… wait, wrong forum.
