The new iPhone 6s and iPhone 6S Plus are already on sale in select countries, and just yesterday we learned that some users are facing issues with the overheating Touch ID sensor. We ve earlier heard about Apple contracting TSMC and Samsung for making the A9 processors. Now, some curious minds have dug deeper to find the performance difference offered by both the chipsets.

Chipworks have already revealed that processors made by Samsung are 10 percent smaller compared to the ones manufactured by TSMC. The teardown reveals that Samsung made chipsets employ 14nm fabrication, whereas the ones by TSMC employ a 16nm fabrication process. While some people may believe Samsung made A9 processors to be a more efficient, it doesn t appear to be the same. Also Read - Apple CEO Tim Cook claims iOS is more secure than Android
Well known YouTubers Jonathan Morrison and Austin Evans have uploaded videos, demonstrating the performance difference between TSMC and Samsung-made A9 chipsets. Both tests reveal the same result iPhone 6s equipped with TSMC chipset offer better battery life.
Jonathan has both phones with 100 percent battery and ran different tests to see which phone drains faster. He shot 10 minutes of 4K video, exported it to iMove and also ran a couple of benchmarks. With the same usage, TSMC model had 62 per cent battery, whereas the one with Samsung chip drained faster and was left with just 55 per cent battery.
The difference of seven per cent may not seem too much, but after the same test was conducted from the leftover battery, TSMC model was left with 24 per cent, whereas the Samsung one had a mere 10 per cent left.
Austin, on the other hand, has a bit different approach for testing the battery life. He ran the Geekbench 3 battery test benchmark with same brightness set on both phones to see which phone drops to 50 per cent first. While the one with Samsung chipset was the first to hit 50 per cent mark with the phone getting a little warm, the one with TSMC chipset not only lasted about 50 minutes longer, but also ran a lot cooler. He also played an hour long video on both phones, but the percentage difference in battery drain was a mere one per cent.
It might not be a big deal on which model you end up with, but in case you want to find out, there is an app called Lirum on the iTunes Store, that you can try out.
