Is there a battery size difference between the 38 / 42 mm sizes?

[ckurt25]

Just wondering if anyone knows if there is difference in the battery size between the 38mm and 42mm watch.

Sorry if this has been covered elsewhere. I did a search and didn't see this as a specific thread.

The 42mm allegedly has slightly better battery life than the 38mm.

check out apple's website ..it says that the 42mm had better battery performance in their tests.
