Yeah I guess in 2 days I haven't fully tested the battery because I haven't even tried the workout feature.
Regarding standing not being accurate, that's exactly it. For example today at 12:40am local time it was saying I had stand up for 5 hours. I put the watch on after 7am, and I sat down for most of my day, so it's way way off.
That official Apple Watch stand looks sweet as hell. I don't want to splurge now, but give it a couple of months and maybe!
The reason I ask about the standing accuracy is because it doesn't actually measure how long you stand. It just checks off whether you've stood for atleast 1 minutes within that hour. The point is that sitting all the time is not healthy so it checks off that you've stood for at least 1 minute for that hour (I assume on the :00 o'clock to the next).
It's not constantly recordings how long you've stood for.
To my knowledge.
