That’s a big selling point for me on the 15 series. I had the back glass break on my 12 Pro this year and learned after the repair that it’s effectively getting a new phone when it’s ‘repaired’. Took me 2 months to get my eSIM deactivated on the new device for a number of reasons that ultimately ended up being a Verizon issue, but that they blamed on Apple until I got Apple to send me another new device that had the same problem.
The replaceable back glass and USB-C are enough for me to upgrade from my 12 Pro. Now my debate is between the Pro and Pro Max…
