Yes, there are basically no reasons to not move to USB-C. Up until this point, I have been saying that it is a matter of convenience. But it is also economical.
The other day, my wife and I were out and planned to get lunch and go back home. We had outdoor seating and it was a beautiful day, so she decided to stay and work.
She did not have her lightning headphones and asked me how much a cheap pair would cost. Well, since it is lightning it would be about 3x as much as a USB-C pair.
I was so close to just pulling the trigger on an iPhone 13 since my iPhone XR is constantly freezing and has terrible battery life. This instance reaffirmed my decision to wait for a USB-C model iPhone.
If the iPhone 15 for some reason does not have USB-C or it is wildly expensive, I am just going to get an iPhone 13 and use that until is no longer works.
I’ve long been a proponent for a USB-C iPhone. When I had an Android phone and an iPad, it was annoying to carry both ports. Now iPads are USB-C, but not mine (Air 3). I got a 14 Pro last year, jumping back to iPhone for the first time in 7 years.
While I’m glad to see the 15 series will likely be USB-C, it will make a kind of annoying situation again, since my wife will be upgrading this year (she’s on an Xr), and so we will be back to bringing two chargers when we travel. But that’s a short term issue.
