Didn't the article note that the test was comparing the 7 and competitor's larger sized phones? It's kind of like noting that a car with a 12 gallon tank (even if it gets 30mpg) can't go as far as truck with a 30 gallon tank (forget about the fact that it gets just 15mpg). And as others have noted, testing 3G phone service seems a bit out of date today, knowing that chips have been updated and designed to be more efficient at LTE service, not 3G. But really, this just comes down to comparing Apple to watermelon and realizing that a smaller battery will provide less usable time.
