I took my series 3 off yesterday and caught the charge ring and it looked to be between 60-70.
Much improved since the release.
My series 2 its tough to wear the Nike over the S3 edition.
 
Series 3 just went on charge after 2 full days of hard use, lots of exercise tracking. I still had 44 percent and could of made it a 3rd day. I always had some left on my Series 2 after 2 days but not as much as my S3.
 
I can go 3 days but don't push it. I'll charge it every two days to make sure it never dies on me.
 
AW0 - Just one day. I usually exercise for 45-60 minutes per day. On those days there's less than 25% left at the end. If it's a long-ish hike, then it doesn't make it through the day.
 
I get about 3 days of use , heart rate monitor is off exercise tracking etc all are off as i use a Fitbit to track my fitness progress.
 
Series 3 No LTE - Two full days with exercise. But on the second night I want to put it back on the charger as it won’t make it through the third day. I usually charge it every night though.

same here. inherited 2 AW0s, same vintage, and getting about 17h per day with 1 30min workout; 15-25% left at end of day on one of the watches. interestingly the other watch must have a thrashed battery, since it sometimes runs out at the 16-17h mark. i have been using that one for sleep tracking.
 
I have a S2 38MM (the size matters when discussing this, as the battery capacity differs quite a bit).
I probably could get two days if it's a light usage day, but I usually charge it every night because a) if I get out of that habit, on the days when I need to charge to (when I've used 2+ hours of workouts) I'll forget, and b) letting Li-Iron batteries get low is not great for their longevity, so I'm in the habit of trying to avoid this for any device where I can unnecessarily.
 
I have to charge my series 2 every week night as I cycle 14 miles to & from work (28 miles every weekday tracked with Strava) and I’m usually on about 50% by the time I go to bed, doubt it would last another day so I don’t risk it.
Of a weekend I leave it and it lasts all of Saturday & Sunday if I don’t do any activity tracking of any kind.
 
I just upgraded from a Series 0 to a Series 3 WiFi, and so far have only been charging it every other day. And even then I’m only at 50%. Consider me impressed!
 
Series 3 LTE starting at 9pm at 100% can last me a week with a charge only when showering and getting ready. That is typically what I do now. 7-8 days in requires an hour to charge. My morning workout can kill 10-15% but that is easily recovered by 20-30 minute shower/ready and then some.
 
The S3 is great. At night it’s down to about 60-70%. If you need to stretch the battery put it in theater mode. That extends battery life quite a bit. I sleep with it in theater mode and still have 100% in the morning.
