Anandtech review of the TSMC n Samsung chip. Read their conclusion summary. Is non conclusive.  Basically I feel is just an overblown issue.

THE CONCLUSION
Wrapping things up then, where do we stand? The short answer is that all we know is that we don't know. What we know is that there isn't enough information currently out there to accurately determine whether the TSMC or Samsung A9 SoC has better power consumption, and more importantly just how large any difference might be. 1-on-1 comparisons under controlled conditions can provide us with some insight in to how the TSMC and Samsung A9s compare, but due to the natural variation in chip quality, it's possible to end up testing two atypical phones and never know it.

To that end I suspect that Apple's statement is not all that far off. They are of course one of the few parties able to actually analyze a large number of phones, and perhaps more to the point, having a wide variation in battery life on phones - even if every phone meets the minimum specifications - is not a great thing for Apple. It can cause buyers to start hunting down phones with "golden" A9s, and make other buyers feel like they've been swindled by not receiving an A9 with as low the power consumption as someone else. To be clear there will always be some variance and this is normal and expected, but if Apple has done their homework they should have it well understood and reasonably narrow. The big risk to Apple is that dual sourcing A9s in this fashion makes that task all the harder, which is one of the reasons why SoCs are rarely dual sourced.

You chaps have such complex characters 
All I care about is my phone having a black/dark face, so that basically means the space grey is my only option. I just don't like using bright faced phones, especially glossy white (reminds me of toilet ceramics) since I find it too distracting.

First time iPhone user here, upper right  area gets kinda hot while video calling:normal?

Haiz....unlucky one, mine is Samsung chip....

bad economy, high price and the fact that is internal changes only could be factors for this.
next year when there is full redesign, I'm sure the hype will be back.

Do people genuinely find Assistive Touch useful, or are they just crazy paranoid about the health of their home button? Serious question, btw. I tried it once and it was just a liquid pain and got in the way more often than not.

Bro... U see my siggy..i have been using android since i also cant remember when.

But once i use this iphone..i think i wont turn back to android anymore until they do something revolutionary..

Iphone is very easy to use..and battery life is awesome compare to my note 5 and s6..I finally realise that it is not samsung..but android itself has some problems that ios doesnt have..they need to optimise more in terms of battery life and the overall os ecosystem

Now for ur question..the camera on the note 5 is slightly better than the 6s+.. I cant deny that note 5 camera is just superb

So you bored using android now..for me I will not close my door to android...I like both:)

Android is not that bad as you said but I do admit that Sammy updates really suck. Like you said, they are more interested in selling their products only. But Sammy have a lot of different models and updating all of them would be a lot of work. 

even other android seller with less model difficult to update their phone..for sure for sammy its more difficult and lot work like you said. Sometimes also the new update its not good.

Officially used the iPhone 6s for one week! Loving it so far! My first ever iPhone!

Some things that I noticed:
1. Fluid fast! Fingerprint sensor is so fast!
2. 3D touch is really, really innovative.
3. Coming from Android, I still need to get used to some things. No back button, and the most annoying one for me so far is no notification icons.
4. Battery life is quite bad. Have to bring my powerbank everywhere now.
5. Like the 1st page says. NEVER, EVER get the 16GB model. I got the 16GB one and I am regretting. Apple should make the base model something like 32GB. Getting an OTG cable soon.

From Samsung s6 edge to iPhone 6s+. Design wise I do prefer Samsung edge. But the fingerprint sensor on iPhone and the OS is the best in term of fast and smooth .No wonder Apple is king of smartphone. Apple iPhone 6s+ 64 GB silver report in

Agree, that's the one thing about iOS that turns me off. From a work point of view, using an Android tablet is faster and more productive, especially when the native email app allow you to attach just about any file you like, and not just photos. USB OTG is also a God sent.

Hey guys, Im using the 6s and s6. previously was using 4s and s4. I would like to share my experience with these phones.
Android phone are generally better in specs. their freedom in OS is like a fire. "Its a good slave but a bad master." Prone to malware that hogs battery, privacy etc etc even when installing only from playstore, android users have to be careful of what they put in their phone. However once optimized well, it can out do the IOS(stock).
IOS on the otherhand, has a well optimized OS and apps that does not need much further optimization, supposedly allowed users to use the phone with ease of mind. (Unfortunately, recent hack of icloud and malware within the official appstores have tarnish this reputation). Because IOS is available in limited device, apps are generally more optimized to perform better in quality and battery consumption.
But if compared to 6S's 1715mAh vs S6 2550mAh, my personal experience, at stock 6s and s6, s6 will initially have better battery life. But as junks get installed more in both device, the 6s retain better battery life than s6. but after optimization of both device (root and jailbreaking) s6's additional raw +48% more battery has gave it better battery life again reaching 2-4 days with mobile data, while the s6 reaches 1-2days (as for now, as the tweaks for ios9 is still limited).

As uncle benny said, i agree that IOS close system is can be annoying even when attempting to perform basic task, eg transfering mp3/ office documents /email. But i have to disagree with the finger print recognition speed as i personally tested both phones... The time it takes to unlock to open an app is actually the same. IOS response to unlocks faster by displaying unlocking animations thus creating an illusion that it unlocks faster.

Camera for S6 blows 6s away is 9/10 situations(partly due to apple decision not to include IOS in 6s). the only advantage of the 6S camera is the FoD and retain of actual colors in the photo.

Apple product at its price is somewhat used by ppl who can. Not sure if true or not for u guys, but Apple does give the "wow" image factor to an iphone user and ppl tend to see apple differently as a phone. And if given a choice, most average ppl would wish  to have the 6S over S6.

I'm summary, I recommend  the S6 for its hardware and 6S for its software. 6S is easy to learn for all level of users, while S6 can be a lil challenging. In terms of functionality, S6 flexibility allow easier to get task done compared with 6S. At the end, its up to the user's personal preference and usage.
If it still does not make sense to you, just imagine cars, which performs better, automatic or manual?

just my personal opinion and may differ from others.

Because i only used Samsung S4, S6 and Xiaomi Mi4i (and iphone 4S and 6S), i cannot comment on other android phone. But I do agree with you that hardware means nuts without optimization. Hence if one does not want to go thru the fuss of optimizing device, I always recommend an Iphone but warn of paying the price for its optimized OS.

I would like to add on that Samsung and Apple has always been copying each other. These 2 companies have been repeatedly suing each other for patent infringement since 2011.(or maybe much earlier?)
Mocking Samsung dropping the battery and ext memory is the same as mocking Apple for abandoning their proclaimed perfect single phone size of 4/4s size and later copying Samsung's S and Note series sizes at 2014. Its okay to swallow own words as people do make mistakes and subsequently improve in the future.
As the saying "Anyone who has never made a mistake has never tried anything new." ALBERT EINSTEIN

Now whats interesting is, Samsung has always been avoiding direct competition (by offering alternate specs like bigger screen, removable battery, ext sd, stylus pen) with apple. Until 2014 where, Apple made the decision to take on Samsung flagship head on by matching its phone sizes at 2014. Subsequently Samsung on the other hand have discontinued their laptop products to divert resources into their mobile dept. Instead of avoiding direct competition again, off goes the removable battery and ext memory Samsung did. It would be really interesting to watch the romance between these 2 companies in the future.

As for myself, im Neutral of both sides. I use the Iphone 6S and Samsung S6 concurrently. These facts i state above is to share my understanding, and not intended to offend any iphone/samsung fans. If i do, i apologize in advance.

There are already in the market various otg devices in market since last year. Most famous is SanDisk ixpand drives. I bought the 64gb unit but seriously it falls way behind vs Android alternatives. I had bought another one where you can even attached a ext microsd card however file copying over is erratic n often faced incomplete copy at 50-60% for files above 300mb n it was a waste of money

for the back button, u just need to swipe right to go back

Why is it so difficult to get AirDrop to work? Both 6s can't seem to find each other even when AirDrop is selected to show everyone.

Must both device/phone be connected to the same WiFi? It should work without being connected to the same WiFi network right as sometimes we don't have a WiFi network to connect to?

I know that feeling. I always look for back button on my iPhone. But I also look for the floating assitive button while I'm on android
