More images reveals fewer chips, streamlined internals — 5 July

A new batch of leaked images have again been outed by 9to5Mac, this time showing a streamlined set of internals, fewer chips and some interesting additions.

Based on the pictures, it seems that the iPhone 6S will boast at least 16GB of storage and a new NFC chip, which will likely plug nicely into the company’s Apple Pay wireless payments system. Although NFC was added to the iPhone 6, the phone itself was using a dated implementation, notes 9t05Mac.

Additionally, more can be revealed by the less cluttered logic board:

One section of the board that previously had in excess of 10 components has been pared down to 3 main chips, simultaneously cutting the number of parts and increasing the power efficiency of the ones that remain.
