How to see if you have a Samsung or TSMC A9 chip in your iPhone 6s

How to see if your iPhone 6s has a Samsung or TSMC A9 chip.

In the wake of the so called "Chipgate," many iPhone 6s and 6s Plus owners are concerned with what brand of A9 processor powers their phones. The mostly unfounded concern arose when, a little over a week ago, some benchmarks showed that the slightly larger 16nm TSMC brand A9 chip was 20% more efficient (in terms of power consumption) than the 14nm Samsung version.

How to enable AT&T Wi-Fi calling on your iPhone

AT&T Wi-Fi Calling Setup

AT&T has started rolling out Wi-Fi calling to iOS devices two-days after the company was granted a waiver from the FCC. AT&T used the opportunity to call out T-Mobile and Sprint who have already been offering the service without permission.

"We’re grateful the FCC has granted AT&T’s waiver request so we can begin providing Wi-Fi calling. At the same time we are left scratching our heads as to why the FCC still seems intent on excusing the behavior of T-Mobile and Sprint, who have been offering these services without a waiver for quite some time. Instead of initiating enforcement action against them, or at least opening an investigation, the agency has effectively invited them to now apply for similar waivers and implied that their prior flaunting of FCC rules will be ignored."

How to see if your iPhone 6s has a TSMC or Samsung A9 chip

Apple A9

Apple has sourced A9 processors found in the iPhone 6s and iPhone 6s Plus from two different suppliers, both Samsung and TSMC. While the design and real-world performance are practically the same, each chip manufacturer is actually using a different die size. The Samsung version (APL0898) is arguably more advanced since it uses a 14-nanometer process, resulting in an A9 with a footprint of 3.78 square inches. By contrast, the TSMC chip (APL1022) takes up 4.11 square inches thanks to a 16-nanometer process. So why does any of this matter?
