I really think there is no chance they go portless and I don’t know why this rumour persists.
Wireless is a mostly bad way to charge phones with a couple of good applications (MagSafe phone mounts in cars, and desk/bedside docks). They’re less energy efficient, they’re bad for the battery, they’re slower, they are less portable, some are noisy (either fans or coil rattle). It would make many cars with wired only CarPlay obsolete, which would be wildly unpopular.
Apple couldn’t get AirPower to be good enough to release – I don’t see a world where iPhones transition to wireless charging any time soon. The next iPhone will be USB-C, aligning with all current iPads and Macs. I don’t think Apple are even particularly against it; they’re just afraid of the backlash they got after changing connector last time and would rather put that off as long as possible.
