After reading 15+ pages on this thread, I think it's safe to conclude that nobody who mentioned they have one or the other made it clear that there's even any difference. Point is moot, in my opinion. But it was a fun discovery. I therefor can't see why anybody can lose any sleep over having one chip over the other, if they can't even tell how it affects their device.
 
I Googled what is listed as "Model" and came up with these two links:

The iPhone 6s Plus makes use of the A9 by Samsung (n66ap) and A9 By TSMC (n66map) processor.​

Perhaps I'm wrong on this...?

Eventually, soon if not with this app, you won't have to pay or download outside of App Store to get this info.
Since that app was in the App Store I tried it and got n66ap for my model number. So I guess mine has Samsung. And this means...??? Mine is eating battery pretty quickly but I am using it like crazy. Oh well, curiosity satisfied. I guess I'd better put a lid on my Samsung snark from now on. ;)

Just checked husband's 6s Plus. His is also a Samsung.

We haven't done battery tests yet but I know his battery lasts a lot longer than mine in a day's use. I think it's Facebook that's draining my battery dry. And FB messenger.

Where the phones are manufactured should be logged as well. Maybe there is a pattern with the factories.
 
How do I check which chip I have in a safe way? Just curious, don't really care.
 
Ok that test was stupid, they didn't use the same phone. It looks like 6s vs 6s plus. Please ignore. All of this is stupid. Go enjoy your phones!

This is interesting part from translate, they managed to measure power consumption of chips:

"use TSMC 16nm processors iPhone 6s Plus although the screen is bigger, but consumes only 314 mA of power Instead of using Samsung's 14nm processor iPhone 6s, but actually more power than the iPhone 6s Plus 70 mA, 384 mA."

The Google translate is rather confusing but I happen to be able to read the original text without Google translate. http://m.mydrivers.com/newsview/449605.html?ref

- While running Geekbench, Samsung chip performed slightly better initially, then it went down, and temperature went up to 40C. TSMC chip performed consistently, and temperature didn't even exceed 36C.
- While running the Rabbit test, Samsung still ran hotter than TSMC. TSMC scored better than Samsung.
- The tester decided to stop the test after ~15min because the iPhone with Samsung chip was uncomfortably hot.
- The iPhone 6S with Samsung chip draws more power than the iPhone 6S Plus with TSMC chip , despite the Plus has a bigger screen. (384 mA vs 314 mA).

I guess the smaller chip has smaller surface area, hence heat dispenses less efficiently than bigger chip? Just my guess.

Should be samsung, very disappointed! I'll return the phone today. Had to return one already because of dark top of screen I hope that will be the last exchange.

Is 4:05 in average battery life for a 6s? I did the test with phone fully charged, disabled autobrightness and brightness to minimum and dim on on geekbench.

Would you say that the 14nm Samsung one got worse battery life than the 6 plus?
 
I find it funny about all the Samsung desire when these recent test show the TSMC to be a bit better in power efficiency and lack of throttling.

However, it still looks like for everyday use there's going to be no visible difference between them.

Well I'm amazed that TSMC is currently showing 1-2 hours better battery life. I think difference is bigger than many would have thought.

I'm not sure that your Battery benchmark was that bad. It was 1 hr 28 min better than Samsung score on this page!

iPhone 6s Geekbench Battery scores can not be compared to 6s plus.

I was probably getting confused on which phone was which. My battery is pretty good then? ^.^
