Im not sure, but I think with an even thicker phone there will be more 
no-geeks who dont care about the freeness who wont buy the phone only 
because its thick and heavy (and such a phone would be heavy).
an the second problem is, the batty we use now is a standard-battery, u 
can buy an battery like this at ebay for 10 bucks, but a custom battery 
sounds very expensive.
i think the key for longer life isn't a bigger battery, but a better 
energy saving.
