Apple choosing to enable the feature on other models is not evidence that those models actually had the issue. Users have only reported widespread instances of shutdowns on 6-series phones. Anything Apple says or does to the contrary is a smokescreen.

I watched my wife's iPhone 6s Plus shut down multiple times in February 2017 when we were in Niagara Falls (both US and Canada) sides. The temps were in the teens (F). Then, in Toronto a few days later the shutdowns continued. I'd never seen that behavior prior to that time or since then. That seems to have been correlated with cold temperatures. When I was able to restart her phone, the battery was around the 75% charged.

the same experience here, my iPhone 5s shutdown in weather under -1 , in more than 35% of battery, also my iPhone 6s on iOS 11.2.6 has a battery drain issue, the only things that surprised me is my iphone 4s on iOS 9.3.5 , the battery is pretty great , and servived much enough, and with cydia enabled forever i can't be more appreciated.

Except they have admitted about the shutdowns, which only affects certain 6S models. This has nothing to do with those battery issues. If you have a model you think has that issue go to the apple.com website. They have a form where you can check by using your phone serial number. Replacement is free and depending on how busy your nearest store is it can be done in a couple of hours.

My 5s had lots of random restarts as the battery got more degraded.
 
My phone was unbearably slow, but iOS 11.3 fixed that somehow. Strangely, it also says my battery is good enough to not be throttled, but it seemed like it was being throttled before. Wonder if they backed off.
The throttling setting is reset to "off" when 11.3 is installed. Only after a subsequent unexpected shutdown is it reenabled. Mine worked beautifully for a couple of days but then randomly quit while I was browsing the internet and the battery percentage was at 27%. It went back to its old, slow crawl immediately after and a check of the battery health setting showed it was throttled again.

I've heard that previous phones were not affected because the CPUs in the 6S and up were such a huge step up in performance from the previous chips, that they would overwhelm the batteries much more readily than older phones, even with the same quality of battery inside. I don't know how true this is though. Does anyone know?
I don't know, but like everyone else, I have an educated guess.

I think that Apple used either flawed batteries, or a flawed engineering design leading to the shutdown issue.

The flawed design could be as simple as putting too small capacity battery in the newly designed, more powerful iPhone 6. They most likely gave up battery space for thinness. This came back to bite them in the booty.

Doing so would have forced Apple to admit to the world there is an inherent design flaw in the iPhone 6-series phones, because no iPhone model before or after the 6-series shuts down when using aged batteries. Admitting that flaw would have necessitated an enormous recall, which would likely have cost Apple over a billion dollars. This is why Apple to this very day refuses to admit the truth.

Really this all could have been avoided if they had simply displayed a message: Your battery is in poor health, we recommend slowing your phone down to prevent unexpected restarts. Do you wish to do this? And then provide Yes or No buttons and a way to change your mind later.

Additionally, if this message appeared, the phones should automatically qualify for battery replacements.....if under warranty, then free replacement, if not under warranty than at the user's expense.

You're assuming they had the best intent in the first place.
 
A degrading battery doesn’t cause a device to shut down, it only causes a device to not last long on s single charge, Apple basically have a design flaw if the device was shutting down in this manner.

And how is it since iOS update is no longer throttling devices that were throttled by default, someone is hiding something

You can disable that throttling now.
 
Can’t confirm. My iPhone 4, 5 and 6s (I skipped the 6) did also ‘randomly’ shut down after about one year of usage, especially in cold temperatures during winter. All got replaced by Apple. This behaviour isn’t at all exclusive to only the 6-series.

If the issue were widespread on those other models then we would be talking about those other models today rather than just the 6-series models.

There was no "widespread instances of shutdowns on 6-series phones"

If that's the case then why did Apple implement the software throttling "feature" to avoid shutdowns?
[doublepost=1523469989][/doublepost]

"Apple has determined that a very small number of iPhone 6s devices may unexpectedly shut down."

If it were a "very small number" then Apple would have never implemented the throttling "feature" for all 6-series phones.

And yet shutdowns were never a widespread issue on iPhones prior to the 6-series or after the 6-series, so everything in that article is Apple's misdirection to convince people there is no issue specific to the 6-series design. Apple has a billion or so reasons for that strategy (ie, the likely cost of a full 6-series recall).
Or there's more to it all and throttling that has been implemented has been helping avoid such shutdowns. As for before the iPhone 6 series, it's more along the lines of what's mentioned in a couple of earlier posts at #12 and #16.

Everbody else here is talking about all models, it seems like you are the only one who tries very hard to make it look like an iPhone 6 exclusive problem - which it isn’t at all. Shutdowns due to a degraded battery could and did effect any iPhone.

If that's the case then why did Apple implement the software throttling "feature" to avoid shutdowns?
Apple implemented the feature after a number of iPhone 6s had been shipped with faulty batteries that degraded way faster than normal and therefore led to a higher number of shutdowns that users complained about during the first winter with the device.

If it were a "very small number" then Apple would have never implemented the throttling "feature" for all 6-series phones.
As explained before, Apple implemented the feature because of an irregular high number of shutdowns of 6s decides that had been equipped with possibly faulty batteries during the first weeks of production. But the feature was made a standard in iOS to prevent any iPhone from sudden shutdowns caused by battery power issues - also those with batteries that had ‚naturally‘ degraded due to age and usage.

And only for the ‚very small number‘ of effected 6s phones Apple offered a free battery replacement service as already mentioned here before.

Please provide references for this. And by references, I mean a large volume of iPhone, iPhone 2, iPhone 3, iPhone 4, and iPhone 5 users complaining about their phones shutting down with aged batteries. A volume of complaints anywhere near the level that occurred for the 6-series phones.

Apple issued a selective recall to replace faulty batteries on 6-series phones. With that recall why would it be necessary to implement this "feature" for other 6-series users?

And that recall had occurred before Apple implemented the "feature" for other 6-series phones that Apple claimed weren't affected, by dint of their serial numbers not being within Apple's very selective range of recalled serial numbers.

And only for the ‚very small number‘ of effected 6s phones Apple offered a free battery replacement service as already mentioned here before.

Now you're arguing my case for me :) If the problem was limited to defective batteries that Apple recalled then why was the feature deployed for all 6-series phones? And I'll expand on this question even further - why did Apple hide this "feature" from users by initially not disclosing it in the release notes?

This aspect of it was addressed in a few replies earlier in the thread.
