46mm S11 has a 363mAh battery (haven't been able to find a teardown for the 42mm S11 yet, but based on their phrasing in the release event it wouldn't be unreasonable to assume 42mm S11 got a similar 10% bump like the 46mm)

the physical battery capacity did increase a decent amount (nearly 10%!), but the "all-day" battery life the S11 claims is also due in part to Apple tweaking how they test battery runtime of one full discharge cycle. you can see a more detailed description below:

anecdotally, I've noticed effectively 0 functional battery runtime difference on my personal 46mm S10 and friends with S11s. both will last a full day with probably ~30ish% charge left with AOD on, 2-3 hours of combined cardio and traditional strength training workout tracking
if battery life is important to you, I recommend getting an Ultra or you can disable loud volume notifications, handwashing detection, background app refresh, AOD, and some other features
tldr; S11 battery improvement looks generational on paper, but is really an incremental-at-best improvement irl conditions and usage

There are typically more S/M watches on sale but I use M/L.
