> Unless you can deliver multi-day battery

Do you really think they couldn't?

The magsafe battery thing is actually pretty neat, but not using it to instead have a thinner phone feels pointless because you still have the giant bulge from the camera.

Apple obviously could create a multi day phone battery, they would just need to make it thicker. But there are 230 million people that buy an iPhone every year. I suspect Apple knows what it's doing.
