I took mine off the charger 12.5 hours ago. It’s still on 63%.
My series 5 would have been on 20% by now.
I did a quick charge this morning (20 min) and got the watch to 92% by 7am... 7 hours later the watch is sitting at 69% with normal use of checking and replying to texts, emails, playing music directly through the watch and so on.
I hate to see that some folks are not having the same great experience I am so far.
