As far as a I know, in the history of smartphones - which I'd say starts in 2007 with the launch of the iPhone - there have only really been 4 (or maybe 5) connectors used on widely sold phones:
1. Apple 30pin "iPod" connector
2. Apple Lightning connector
3. Mini USB (I don't think this ever appeared on anything but blackberries and cheapo flip phones?)
4. Micro USB
5. USB-C
So, while I agree that cable changes are annoying, and I support standardization efforts, "a new one every other year" is just not how it's ever been. 5 connectors in 15 years. The 30pin connector reigned from 2007 to 2012, and on the android side, micro USB was dominant until around 2015-2016 when USB-C started showing up on phones. Realistically, it's been a new connector every ~7 years.
