I think the charging port is the next one to go. Just use wireless charging, roast the battery and buy a new phone when the battery finally dies after a few years. However, if the battery really is replaceable, it’s going to change the economics of this plan.
I don’t think so. They would still need a way to connect to the phone for diagnosis reasons and all that, or to connect to it via iTunes.
That’s still wired, so they can’t get rid of it entirely.
NFC or something to that effect can be forced"on" with their special charging connection… Or something like that
Would be horrible for data rates but it could be done
Just so you know, the Apple Watch no longer has a diagnostic port. It’s all 100% wireless now. Source
Apple has been tinkering with this idea for a while now, and it’s already in use. Next, they just need to do the same thing with the iPhone, and they’re ready to ditch all cables.
