New iPhone 6S and iPhone 6S Plus users are divided, literally. Not about screen size, but about which company made the processor chip inside their iPhone. It turns out, Apple used two different manufacturers; Samsung and Taiwan Semiconductor Manufacturing Company (TSMC), for the A9 chip inside the latest iPhone models.

But what's the difference? Apparently the Samsung chip is smaller and some have claimed that the battery last longer with the TSMC version. In one benchmark test, apparently the TSMC version lasted for almost 2 extra hours!

So now, if you are a iPhone 6S user, you are probably wondering which company's made chip is inside your iPhone. Unfortunately, there's no way of knowing without downloading an app. An app that can tell you your chips model number is the free app Battery Memory System Status Monitor.

Once you've downloaded the app, tap the 'System' tab and look for the devices model number, which should be right at the top. If your model is N71MAP or N66MAP, congrats, your iPhone has the TSMC A9 chip. If your model is N71AP or N66AP, then you have the Samsung made A9 chipset.

But don't worry, if you have the Samsung chip, Apple has commented and said that the 'tests' don't represent real-world usage, and that there may only be a small 2-3% difference.
