Yeah, I dunno, I have a S10 42mm. I charge it to 80-90% in the morning while in the bathroom, and it lasts me until the next morning with 10-20% left.

I have always on display on, and all the tracking stuff on like Afib, sleep apnea, wrist temperature, noise levels, fall detection, etc. I typically do a 30 minute walk during lunch that I do a fitness activity for, and a 2 hour pickleball session most days of the week where I also fitness track it. I do not use low power mode, and by the next morning it's got the 10-20% left. It only takes about 15 minutes to charge from 10-20% to 80-90%.
