iPhone not migrating to USB-C or getting Touch ID on power button any time soon
Analyst Ming-Chi Kuo believes that market and financial benefits will mean Apple skips USB-C for iPhones, and will also not move Touch ID to the power button at any time in the near future.

Despite moving the iPad Pro to USB-C charging instead of Lightning, back in 2018, Apple has kept the iPhone on the older technology. Now an analyst says it appears Apple will neither adopt USB-C nor Touch ID on the iPhone.
"The market expects the iPhone to abandon Lightning in favor of USB-C and equip the power button with the Touch ID sensor," writes Kuo in a note seen by AppleInsider. "Our latest survey indicates that there is no visibility on the current schedule for the iPhone to adopt these two new specifications."
Kuo understands that there are technical issues around waterproofing, but says he believes there are market pressures involved. Specifically, Apple's Made for iPhone (MFi) program is a profitable business that would be affected.
"We believe that USB-C is detrimental to the MFi business's profitability, and its waterproof specification is lower than Lightning and MagSafe," continues Kuo. "Therefore, if the iPhone abandons Lightning in the future, it may directly adopt the portless design with MagSafe support instead of using a USB-C port."
"At present, the MagSafe ecosystem is not mature enough, so the iPhone will continue to use the Lightning port in the foreseeable future," he says.
This isn't to say that Kuo thinks the technology, particularly regarding Touch ID, is not adequate, however.
"We believe that the iPhone will significantly improve the user experience if it adopts the power button with the Touch ID sensor. However, currently, there is no visibility on the timing of adopting this new specification," he concludes.
Apple implemented Touch ID in the sleep/wake button on the iPad Air 4.

For iPhones, there's little, if anything USB C can do that the lightning connector can't, and physically the lightning connector is actually better, IMO. I has detents giving a more secure lock when you plug it in, and since USB C is a coaxial connector there's a center tab on the female connector which potentially can get bent, but more importantly for cell phones, makes it more difficult to clean lint and debris from the port.
Some sort of Touch ID would be nice since we're all wearing masks now - either in the screen or in the button. Apple already has a button-based Touch ID for iPads, so it would seem natural to incorporate that into their phones.
So that MFi program is probably just a fraction of that and overall would represent nothing but a rounding error.
My source for the graph below is from https://www.statista.com/statistics/382260/segments-share-revenue-of-apple/.
Even then there was a whole lot of chest thumping going on about Apple screwing over the poor consumer wanting to sell extra accessories.
You'll be able to buy a used Apple Car before that happens.
Nominally people would need to buy fewer cables if a USB C cable could serve as a 'universal' cable. In reality, I don't think it would make much difference. Theoretically, a cable used twice as much would wear out twice as fast. There's a large enough base of iPhones that there's probably as many or more lightning cables in circulation than USB C cables right now and people tend to buy dedicated cables to have where they need them.
In the end, I don't think it would make a big difference either way.
