Apple is often criticized for their endless obsession with making everything thinner. It seems as though they pick a reasonable battery life target, and make every generation of iPhone as thin as possible while still meeting that target.
Customers, on the other hand, seem to want more battery, thickness be damned. As someone who can't make it through the day on a single charge, I disagree.
More battery sounds great, of course. Who wouldn't want 2 or even 3 day battery life out of a phone? Like anything, longer battery life comes at a cost, and I'm not talking about money. Let's try something, shall we?
If you happen to have two iPhone 6's nearby1, put one on top of the other. Now try to use that superphone. If Apple had kept the thickness of the iPhone 3G and just increased the battery life, it would look something like this. 2 Would you use this ultra-thick, ultra-heavy monstrosity in 2014 just for crazy battery life?
If you are one of the three people nodding, don't worry. I'm sure Mophie is hard at work on a giant battery case for you. The rest of you get my point — thinner phones are just plain nicer to use, at least to a point.
We will get to a point when making a phone thinner is just silly. I don't know where that point is, but I do know that the iPhone 6 feels better in my hand than my 5S did.
