Will they be able to? If the law says you must have a usb-c port, then it seems like you won't be able to have an entirely wireless device.
I guess the law is also fine with having no port at all. It's kinda late now for Apple to switch to USB-C, they could and probably should have done it years ago. Macs and iPad Pros already have the USB-C port. It's said that Apple has plans for an iPhone with no port at all, and why not just skip the USB-C port and make an iPhone with no port at all.
The rumor is that the 2021 iPhone will have no port whatsoever. I think not because some EU regulations demand one unified port by 2021 (it'll be USB-C for sure, it's the most common one today), but because of Apple being Apple. Without a charging port, they can force customers not only to buy more accessoires like Wireless Chargers and Wireless Earbuds, but also they basically force you to use their wireless solutions instead which will cost you. Apple Music or Spotify (10 $ / month) is the wireless alternative to your own music library which can cost nothing if you import your own MP3s or bought CDs into iTunes, you can still sync everything with iTunes or in the Finder if someone uses macOS Catalina. Well, i guess you can still use the iTunes Wireless Sync, if your computer has inbuild Wi-Fi, my Desktop doesn't.
Backups would have to be done with iCloud instead, and the free 5 GBs isn't enough to backup an iPhone loaded with apps, photos etc... so you would also need to pay atleast the 0.99$ / month to get the 50 GB plan.
Can you imagine that Apple would give you a free wireless charger or even AirPods in the box? Not me. Good that there are cheaper wireless chargers (mine was 15$) or wireless earbuds out there.
Now, to be fair, all the things i listed above won't cost much for one individual iPhone user, but Apple knows that there are millions out there already paying for their subscriptions on a monthly basis. If someone wants that, it's fine. It's a nice addition and it doesn't cost much.
But why pay for a music subscription if you don't need it, even if it's only 10$ a month, or pay for an iCloud plan if you don't use iCloud (for backups), even if it's 99 cents? I have a huge music collection, and it also includes songs bought off iTunes or from CDs i have bought years ago. Not everything i have was ripped off YouTube.
Most people don't even manage their phone using their computer. They manage everything wirelessly. I have seen a couple Instagram posts or YouTube videos focusing on the rumor that the 2021 iPhone will have no port, and the number one complaint people have is: I have to use a Wireless Charger.
I don't think i need to say that i will not buy an iPhone if it has zero ports. I already compromised on the Headphone Jack, and now i have to use third-party dongles for my 3.5 mm headphones. I had 2 of the 3.5 mm Adapter Dongles from Apple, and they failed pretty early on.
Imagine someone does an over-the-air iOS update, and the update process fails and the phone is bricked and will no longer work. It does happen from time to time for a small minority, atleast. You cannot just use Recovery Mode to restore the iPhone using iTunes, because it needs a connection to iTunes, a wired one. Wi-Fi doesn't work if the phone is bricked or switched off. It probably also limits the use of Jailbreaks. So you need to visit the Apple Store and maybe even pay for the service if your one-year warranty period is over.
So Apple just wants to fork more and more money, it's not really about the customer. That's why i meant i rather have an USB-C port than no port.
I don’t understand why Apple should bother with switching to USB-C in 2020, if they have plans for a portless iPhone by 2021? Unless they are being forced by the EU to use USB-C for the late 2020 model already. If the rumor doesn’t turn out to be true, then the 2021 iPhone must have USB-C.
