iPhone 6S Chipgate: How to Determine Which A9 Powers Your iPhone


Chipgate: a term that’s starting to spread throughout the Apple blogosphere like wildfire. But what does it mean? Essentially, Apple contracted two companies to manufacture the A9 chips that power the iPhone 6S and iPhone 6S Plus: Samsung and TSMC. Interestingly enough, the latter of the two appears to offer significantly better battery life! Continue reading for not only an explanation as to why, but also for a quick guide on how to determine which A9 chip powers your iPhone 6S, Samsung’s or TSMC’s!

During a 50% discharge battery test using Geekbench, the TSMC A9-powered iPhone lasted approximately 50 minutes longer, which equates to a 1.5x difference in battery life!

Furthermore, the temperature of the TSMC-based iPhone was also noticeably cooler. Having said that, lighter real world tasks equaled a minimal battery 1% advantage of the TSMC, but power-users who utilize apps that require more system resources will certainly notice a difference in battery life between the two.

Okay, so with the preliminary data out of the way, how do we determine which manufacturer’s chip powers our iPhone 6S? Easy, using the process outlined in the above video (or by following the written steps listed below).

Step 1. Download and install the required software to accurately determine the special identifier associated with your iPhone’s A9, being iMazing (here).

Step 2. Connect your device to your computer and launch iTunes, ensure that a connection is established between the two. If this is the first time connecting your device to the computer, you’ll be required to authenticate the connection.

Step 3. Launch iMazing, click “Get Info“, scroll down and look for the “Hardware Model“. Match the identifier with the below options to determine which chip powers your iPhone 6S.

Samsung: N66AP

TSMC: N66MAP

Is chipgate destined to become the next bendgate? Only time will tell, but one thing is for certain: the manufacturer who’s A9 your iPhone features makes a difference in battery life during more intensive tasks.
