The iPhone's battery takes up a gargantuan amount of its internal space already. Multiplying the battery size by 7 would end up doubling or tripling the device size easily. See the iFixit teardown of the 4: http://www.ifixit.com/Teardown/iPhone-4-Teardown/3130/1 http://www.ifixit.com/Teardown/iPhone-4-Teardown/3130/1
It's truly just an incredibly hard problem to solve.
