Comment fill the extra space with batteries (Score 2) 357
Almost half the population don't have pockets, and thus the compactness of the phone isn't a big issue to them (these people are called "women" - have you heard of them? They carry phones in "purses").
Perhaps for them it makes sense to have bigger phone, and fill the extra space with batteries. Wouldn't it be great if it only needed charging every two weeks? A bigger phone is also easier to hold in between the shoulder and neck to allow brief handsfree use.
