I wear mine while sleeping and in the shower, the two most typical times people charge their AW, and I still have no issues with battery life. I charge mine at some point during a time I’m going to be sitting for an hour or so, and that’s plenty.
It's so disproportionate to other brands out there, though. I have a Garmin forerunner 935 and it lasts weeks. My Fitbit charge 4 lasts like a week or so. I don't want to have to remember to take it off; if I forget even for one days the Apple watch is a useless expensive bracelet. I'd pay double its current price if they make it last a week.
I've gone running in the morning with the Apple watch and it drains it so substantially that it won't even last a day. This is not acceptable.
