A8X probably uses more power, and would thus result in unsatisfactory battery life if they had used it.

Do you really think Apple didn't use the best processor it could in the iPhone 6? Why would they shortchange their own product?
 
Heat dispersion or the lack thereof. Putting an A8X into an iPhone would be a waste if its throttled to an A8 or worse. Read up on Anandtechs heat dispersion testing with the Mini, keep in mind the Mini is much larger then the 6+.
 
no he won't. X series are for ipads. there's a reason for that.

Correct, but Apple has been known to change the rules, so I wouldn't put it past Apple to use the larger volume afforded by the Plus to use an enhanced version of the A9 in the 6S Plus. That said, if there is a difference between the 6 and 6 Plus, it'll probably be in clock speed and TDP and they'll probably continue to reserve the A9X for the iPad, which seems to have MUCH more powerful graphics.

On a side note, for those complaining about the lack of A8X in the 6 Plus, it's worth noting that the A8X probably is a much higher TDP SoC than A8 and may have run down the 6 Plus battery more rapidly (which is one of the best features of the 6 Plus over the 6).

Is your second question serious?

I see what you're saying, but relatively strong Android competition keeps them from seriously crippling the product. Also, If the 6 Plus had the same SoC as the iPad Air 2, then they would be short-changing the iPad (which they sorta did with the OG iPad Air) because it can certainly accommodate a higher TDP SoC than the 6 Plus.
 
So now that everything has been announced we have hit the throw anything at the wall and see what sticks threads.
