In September 2012, Apple announced the Lightning connector with the promise of being a “modern connector for the next decade.”
They specified 10 years (and I believe they said this because of the huge backlash of switching from the 30 pin connector) but I don't know if they were truly saying it was going to last 10 years. Either way I'm glad they're switching and I'll probably turn in my 12 Pro for USB-C even though this phone is fine as is. Just hate carrying extra cables when I go on vacation and such.
Also don't get the iPhone vs Android "war". When I tell people I've gone from Android to Apple to Android and settled on Apple people think I'm crazy.
