Chipgate: Did you get the good A9 or the crap A9 in your iPhone 6s/Plus?

“With the release of the iPhone 6S, it has come to light that Apple is splitting the manufacture of its A9 processor between Samsung, its hated rival and at the same time business partner, and TSMC, the leading chip manufacturing company in Asia,” Andy Patrizio reports for ITWorld. “The split is said to be 60/40 in favor of TSMC.”

“As it turns out, the chips from the two firms are not identical. The site Chipworks, which specializes in teardowns and reverse engineering devices, notes that Samsung uses 14nm while TSMC uses 16nm,” Patrizio reports. “The TSMC chip is just a bit larger – 104.5 square millimeters vs. 96 square millimeters for the Samsung chip – but it shouldn’t be much of an issue because it’s still the same A9 processor design from Apple. If anything, it should favor Samsung because it has the smaller chip, right?”

“Apparently not,” Patrizio reports. “One Reddit user posted tests of a pair of 6S Plus phones and found the TSMC chip had eight hours of battery life vs. six hours for the Samsung… A second set of tests showed the phone with a TSMC chip is ever so slightly faster than the Samsung chip in the benchmark tests and the Samsung chip runs a few degrees hotter.”

MacDailyNews Take: Apparently Samsung’s chip stamping operation takes after their phones.

“There’s no way to tell if you’re getting stuck with a Samsung A9 processor when you purchase your iPhone 6s in stores or online, but you can find out whether you got saddled with a crappier processor with some help from a couple of apps,” Buster Hein reports for Cult of Mac.

“Free iOS app Lirum Device Info Lite is the easiest way to find your A9 processor info,” Hein reports. “If you have a Mac, you can check your device info using the iMazing app.”

MacDailyNews Take: Looks like Samsung didn’t steal all of TSMC’s trade secrets, after all.

Thank Jobs in heaven, all of our iPhone 6s Plus units have TSMC A9 processors inside! Unfortunately, if these benchmark reports are true, some Apple customers are going to feel cheated over this. Seriously: Markedly less battery life, runs hotter, and it’s a total crap shoot whether you’re buying one or not? Seriously, Apple? Who at Apple thought selling two differently stamped processors as the “A9” was a good idea and do they still draw a paycheck? As shareholders, we’d like to know the answers. If these processors are really not that different, then Apple needs to issue a statement, with proof, ASAP. If this is FUD, nip it in the bud (for a change).

If this isn’t FUD or a mistake by the testers, then this is like Ford selling a “Mustang” with a welded hood. Some of them come with 5.2L V8 engines and some of them come with 3.7L V6 engines, but Ford just calls them both “Mustang Engines” and you don’t know which one you’ve got until you can get it to the mechanic to pry open the bonnet.

The iPhone 6s/Plus with a TSMC-stamped A9 processor is simply more valuable than iPhone 6s/Plus units stuck with crappy Samsung-stamped A9 chips. We’re not sure what can be done about that at this point, with millions sold (recall?), but we bet some lawyers are drafting up class action lawsuits as you read this. And, you know what? If these tests can be widely replicated, they’re probably right to be doing so.

Now, who’s stamping out the iPad Air, iPad mini, and iPad Pro chips, Apple? We’d like to know BEFORE we shell out for them. In fact, we’d like to run Lirum Device Info on that iOS device in the Apple Store, so we know what we’re getting. We despise supporting thieving Samsung in any fashion, anyway.

Apple Return Policy: For any product in its original, undamaged and unmarked condition, simply return it with its included accessories and packaging along with the original receipt (or gift receipt) within 14 days of the date you receive the product, and Apple will exchange it. We advise doing so, over and over, if need be, until you get the best processor in your iPhone 6s or iPhone 6s Plus. Buy it. Open it. Install Lirum Device Info. Run it. If you have a TSMC phone, you’re good to go. If not, return the inferior iPhone and repeat the process. Customers shouldn’t have to do this, Apple. Customers should be satisfied they have the best of the best, Apple. This doesn’t seem like a satisfactory buying experience, Apple.

Again, if these processors are really not that different, then Apple needs to issue a statement, with proof, ASAP.

Bottom line: Samsung makes crap and, if these processors really prove to be so different, Apple really screwed the pooch this time.

UPDATE, 5:22pm EDT: In a statement to TechCrunch, Apple claims iPhone 6s/Plus’ A9 battery performance only varies 2-3% between TSMC and Samsung variants in “real-world usage.” So, if you’re shooting a time lapse video, a feature that Apple has promoted and offered for years, and your iPhone 6s with a Samsung-stamped A9 runs out of battery significantly faster than another iPhone 6s with a TSMC-stamped A9, that’s not of concern to Apple nor is it supposed to be of concern to the customer? That’s a specific case of “real-world usage” that is expressly offered and promoted by Apple, no less. Surely the lawyers will take note of that fact, too.

We’re not satisfied with Apple’s statement and Apple customers should not be either.

  1. I found this helpful nugget in International Business Times:

    If you are interested in finding out which manufacturer made the A9 chip inside your iPhone 6S and iPhone 6S Plus then all you need to do is download the free Lirum Device Info app from the App Store. After running the app, if your phone shows the codes N66AP or N71AP then you have the Samsung chip, while if it shows the codes N66MAP or N71MAP you’ve got the TSMC version.

    1. Too bad. On the bright side, you’ll be eligible for a 50-cent iTunes gift card in approximately six years when the class action lawsuits have been combined and finally settled.

      In the meantime, enjoy your hotter (therefore sooner to throttle down), more battery-draining iPhone! Or take it back, as MDN suggests.

  2. If everyone really thinks the difference is significant, Apple just needs to add $25 to the price of one, and subtract $25 from the price of the other, and allow exchanges to those who give hoot.
    Of course if there was a difference charged between the two, the same complainers would say that the difference is insignificant and the price difference too great!
