Then you have an iPad 2 with a 6930 mah battery (using average voltage calculation) and it has a 10 hour battery life. Guess what? 30 minutes of that battery life advantage comes from solely the ipad's larger battery.
My argument? It is your supposition that the 2011 iPad battery is larger than the 2010 iPad battery, even though Apple advertises them as 25 WHr and 25.1 WHr respectively. I'm still waiting on some semblance of proof.
An ifixit tear down is some sort of proof that Apple is gaming their battery size advertising, even though ifixit themselves don't find anything strange with it. For what reason Apple would game their battery rating, not their battery performance, their battery rating, I do not know, as the end-user performance of the 2011 iPad is about the same as the 2010 version.
It's a rather strange line of thought. What is the 2010 iPad battery rating in mAH?
Lastly, amp-hours are not a unit of energy. It's entirely dependent on the voltage supplied which varies in use, and not to mention the current varies too. That the mah rating doesn't precisely match a WHr rating isn't surprising whatsoever.
