Not created equal: Some iPhone 6s' better than others

Not created equal: Some iPhone 6s' better than others
Apple

This news about the new iPhone 6s and 6s Plus is a little tech-y, but stick with us. During the launch, Apple revealed that both phones use a powerful A9 chip, but after the launch tech websites reported that Apple was using two different manufacturers to provide the A9 chips. One is TSMC and the other is Samsung.

Now it's turning out there appears to be some significant differences between the two A9 chips. A poster on reddit compared two iPhone 6s Plus models, one with the TSMC chip and one with the Samsung chip, and found the TSMC chip provided about two hours more battery life than the Samsung chip in repeated tests.

Other sources, including ones in China, have gotten similar results testing the chips against each other. One test found the Samsung chip iPhone 6s ran a few degrees hotter than the TSMC chip model.

MacRumors asked an expert from Primate Labs about differences in the chips, and he told them he'd heard TSMC's 16-nanometer process  was better than Samsung's 14-nanometer process when it came to power consumption.

MacRumors clarifies that "any impact on real-world performance has yet to be firmly established," but who wouldn't want an extra two hours of battery life out of their phone? Unfortunately, at the moment there's no easy way to tell what chip your iPhone is using.

One unofficial app has already come and gone, and most of the other methods are dangerous. The good news is that even with the Samsung chip, the iPhone 6s still performs as Apple promised. It's just that the other one performs better.

If and when definitive information is released about the difference between the TSMC A9 chip and the Samsung A9 chip, or an easy way to figure out which is which, we'll have it for you on our Happening Now page. Let us know in the comments if you feel Apple burned some of its customers with the difference in the new chips, or if the difference is negligible.
