And this article does not even mention actual speeds for the $799+ regular plain ol' iPhone 15 and 15 Plus.
Those cast-off children of the PROs, are outfitted with a USB-C shaped connector port, but wired so that it will only EVER transfer data at the year 2000 USB 2.0 specification. \
Look it up yourself on the Apple Spec pages. Finally they come clean (you know... that the fabulous Lightning connector of iPhone 14 and all prior was also USB 2.0 speed rated as well. For-ev-er.
Those commentators who are truly apple fanboy apologists try to make light of it by saying just go and buy a better cable -- well one should not have to do so, and two, that only works if you buy the iPhone 15 Pro. No cable no matter how expensive will not make an iPhone 15 or 15 Plus transfer data faster than USB 2.0. E-v-e-r.

And that 480 Mbits/sec -- that is a MAXIMUM throughput in IDEAL LAB conditions. Not what you will find in everyday real life home and office.
Sigh.
Apple you really show your true greed colors here.
