The new Apple iPhone 6s and iPhone 6s Plus come with the brand new Apple A9 system chip that is a huge improvement over the A8 used in the iPhone 6.
So how do you check whether your new iPhone 6s has a Samsung or a TSMC version of the Apple A9 chip?
Luckily, this is not a hard task. You can download one of the many free apps that report the model number for your new iPhone, like the Lirum Device Info app right below.
Once you download it, you just open it and scroll down to the 'Storage and Model Information' section. What you are looking for here is the 'Model' number. And here is how to decipher the meaning of the model number:
N71AP - Apple A9 made by Samsung
N71MAP - Apple A9 made by TSMC
N66AP - Apple A9 made by Samsung
N66MAP - Apple A9 made by TSMC
Right below you can see that we have the N71AP, an iPhone 6s with a Samsung-made Apple A9. What's yours?
