USB-C puts the parts that wear out quickly in the cable where they belong.
Really? In another life I worked at an apple store genius bar, and can't recall ever seeing a failed lightning port (physical damage aside). You know what's extremely common though? Schmutz. The port picks up pocket lint, and then the connector packs it all down to the bottom of the port. Eventually your phone stops charging. Often the gunk is packed so tightly it's not obvious even looking with a flashlight that there's anything in there, or that the connector isn't sitting properly. Just dig it out with a pin and you're fine.
Obviously I don't know what happened with your phone or etc. All I can say is in my experience (which is sadly extensive), if you had your phone replaced for a failed lightning port the real problem was almost always schmutz + incompetent tech support.
Edit: Didn't notice jen729w's comment when I posted. So... seconded.
That's a great tip - it never occurred to me and I've just been living with a unreliable connection for months.
(I notice the lint in there because the Lightning cable doesn’t quite snap in all the way; each time I’ve pushed it in, I’m compressing the lint up at the back of the port, and eventually it gets too much and prevents a solid connection. Only happens about once a year, but it happens.)
Looking at a USB-C port, there’s still space for lint but much less space to get in and remove it. Can anyone with a USB-C phone share their experience?
You anticipated my experience exactly. My iPhone 6 got lint impacted as much as my Pixel, but it was a lot easier to fix the iPhone. Lightning does seem to require a more solid connection. USB-C will work longer with a "partial connection", which really just means I'm going to wait longer to clean it out.
Edit: I've never gotten any lint inside any of my USB-C cables though. Looking at the cable in front of me, it would be a bitch to clean out.
Actually, I'm not glad you mentioned it since that makes it even more perplexing. I was glad because if a port ever failed I would not have easily diagnosed it because I thought they were pretty good. But it must be my fault the cables are failing....
Another issue with lightning: the contacts arc. The middle pin on any non-brand-new cable is almost always a bit burnt — it’s pretty easy to see. I don’t know whether USB-C has mitigations for this.
I seriously don't understand the logic here. I've never had a port fail on me.
