What happens if the "7S/7S+" have a feature that the "8/Pro" does not?

So we now think the 7S/7S+ will have glass backs, allowing for inductive charging. They will also likely have Touch ID, which the 8/Pro may not have. It seems likely the 8/Pro will likely reintroduce Touch ID next year (Touch ID has spread across the iPad and Macbook, so I don't really see Apple abandoning it). The 7/7S+ may actually be pretty big upgrades.

What if the 7S/7S+ have some other, hook feature that is left out of the 8/Pro?

Apple isn't abandoning Touch ID for the sake
Of reintroducing it next year again. That's a poor business practice and would reflect Negatively on them. And the iPad and MacBook are completely separate products from each other. That's like saying Apple will bring back the 3.5 Jack next year because the iPad and MacBook have it. The iPhone is an entirely different product with other innovative technologies.

I don’t really think so. If so, Apple will epic fail. People who spents a lot of money in best iPhone will see obsolete their phones just a year later. It sounds pretty unprovable. I think that Touch ID will be deprecated in some years by a great, incredible secure fast and never seen Face ID which we can see as first gen on iPhone 8/pro.

Touch ID will never be on an iPhone again, after the 2018 iPhone SE upgrade, if there is one. The last thing that would ever happen is removal of Touch ID and then the bringing back of Touch ID.


Here's the thing: Touch ID is phenomal. It functions perfectly, instantly, highly accurately, and it's extremely secure. It is absolutely great on anything Apple puts it on. Face ID is merely a potentially superior methodology. It need not replace Touch ID across the board for many years.

It's bound to happen because OLED is a better screen tech and will have some "additional" features in all likelihood.

Better Battery Life,
More secure and efficient FaceID,
Likely better camera (4K60fps + wide angle front),
Larger display for media (when watching video I reckon the whole 5.8” will be used),
Higher resolution OLED display (true blacks, more vivid colours etc),
Screen size of the plus with the small body of the 4.7” (best of both phones),
Specs might be slightly better also.

To name a few- certainly sells the phone to me.

I insist. In my opinion, the future will be a wonderful FaceID. So Iphone 8/Pro won’t miss a Touch ID because next gens iPhones won’t either have it.

I think this post allow us thinking in this not too far future with FaceID (right now iOS 11 keyboard has recognized the word and corrected to that uppercase format.... mmmhhhh)
