I'm trying to find information on the capacity of the 42mm apple watch. The fixit teardown revealed that the 38mm carries a 205mah battery. Assuming the 42mm is 10% bigger in two dimensions and all components just scale, then you'd expect the battery to be 240mah.

So far the only thing I could find is this picture: http://www.techinsights.com/teardown.com/apple-watch/ that shows 3.78 volts and 0.93 Whr for the 42mm. Whereas the 38mm has 3.80 v and 0.78 whr. So that implies a 243mah battery. Can anyone confirm that?

I would have thought the S1, speaker, ports, etc would have all stayed the same size wrt the 38mm, so that would leave more room for a bigger battery?

Eitherway, remarkably energy efficiency of these devices.
 
I've honestly looked for this information everywhere since launch and I can't find anything regarding the mah battery size in the 42mm Apple watch. If anyone knows, please chime in.
 
.93Wh/3.78V = .246Ah which is exactly 20% larger.
Screen is 121,680px/92,480px = 31.57% more pixels or more load for the 42mm.

The engineering is massively impressive...
