I don't see how "1.11Wh" can be considered a step down from "1.11Wh"! They are identical numbers. The trouble with comparing mAh values, is that they are meaningless without knowing the voltage. And (knowing that W = VA) ...
3.82V * 2.900Ah = 11.078Wh (iPhone 7 plus)
3.80V * 2.915Ah = 11.077Wh (iPhone 6 plus)
Which means they are exactly the same, bar the least significant digit (which is in the 7's favour)!
Audio Jack and Water Resistance strike me as being somewhat mutually counterproductive. I, for one, am very happy to see the poxy 3.5mm Jack consigned to history.
Any thoughts about "BENDGATE" - as this phone is lighter than last year's model, will it be bendy, like the original 6-plus? Or pretty rigid, like the 6S-plus? What type of aluminium have they used this year?
I know it's Apple's term, but the non-wideangle camera is not, by any definition, "telephoto". It's actually a "standard" lens, roughly equivalent to a 55mm lens on a 35m camera.
The display seemed to come off really easily, and your pics don't show all the messy glue residue we normally see. But you don't mention its thickness or strength, compared to the wafer-thin (and shattering) Microsoft Surface Pro 4.
Also, that unibody shell is one helluva lot of machined-out (and so pretty thin) alumin[i]um - has Apple used the same 7000 series alloy as in the iPhone 6S/6S+ - or are we waiting for Bendgate Pro?
