go ahead and make the phones components thinner, just make up the difference in a slightly better battery life or slightly faster processor or something.
If the rumors are true, the next iPhone will be a 4.7/5.5" sheet of paper.
I already think the iPhone is a bit too thin for comfort in my hand. But it's perfect with a case on it so I guess its the best of both worlds for those who like it thin, and those who like it thick. (There must be a euphemism in there somewhere.)
Maybe something like this...
I have to admit, that is one sexy looking mockup.
Would be adding the iPhone back to my shortlist if that is the next one.
Apple generally boosts battery life AND reduces bulk. It's not a binary either-or.
Meanwhile my Android friends have to carry extra batteries, chargers and cables everywhere, and I STILL can't call them in the evening because they're out of power. Their phones drain even when used lightly or not at all. Obviously, they have the wrong apps installed and are not managing their processes and resources diligently. Problems that plague many Android users; the same, thankfully, cannot be said of iOS.
You know, iPhone isn't really good at battery life. There are lots of Android phone out there gets longer battery life than iPhone. Just let you know...
