My Series 6 Apple Watch lasts from about 8am to midnight every day. If I wanted to sleep while wearing it I'd just take it off around 11pm and it'd be done charging almost every time by midnight, sometimes even sooner.

I used to religiously wear Pebble watches because they lasted forever between charges. But in all honesty I just don't find the one day battery life of AW to be that bad considering how quickly they charge. IMO they do have all-day battery.
