One of the major UK newspapers has run with this now

Let’s see what Apple’s response is beyond “no comment” and which other mainstream news outlets pick it up.

You don't seem to get that people won't know that the poor performance is battery-related.
Why would someone who's getting alright battery life and iOS says the battery is healthy go and spend money to replace the battery? Wouldn't they just assume iOS is running slower on it?
Apple doesn't let anyone know that they throttle based on this, so it wouldn't cross anyone's minds. I'm sure if it were up to Apple, the user would interpret the slow-down as a signal to buy a new phone.
And do you even realize how ridiculous it is to hear things like, oh it's running slow? That's a shame... guess you'll have to buy a new battery or a new phone! How anti-consumer can Apple get?

He asked where Apple says it, not what you can make by browsing tech subreddits and interpreting Geekbench score distributions.

For the benefit of the user huh?
Go back to sleep.
Yes, a slow phone is better than a phone that just shuts off at random times. I would see a phone thats always on, as a benefit to one that is not.
It would be so easy if Apple just allowed easy battery replacements.
Apple rarely responds to wild speculation.
I'm sure Apple's lawyers would respond if a newspaper accused them of doing something evil though.
Rene Richie has written up a nice explanation and given his thoughts:

I understand the last parts of your reply, and the IR was something I wasn’t considering.
As for the first part of your response, I’ve posted here previously about my personal experience with our iPhone 6 battery that they would not replace the battery, so I know what I’m talking about there.
They need to update their policy and battery testing procedure to more accurately pick up the batteries that are due for replacement under AppleCare.
And they at least need to give us the notification about our worn battery needing to be replaced and that it will result in lowering CPU speed to prevent sudden shutdowns.
It seems their private or hidden algorithms inside iOS, for detecting when a battery is worn enough to reduce CPU speed, are better than the ones they use to tell the customer that their battery is fine, when it’s not fine.
Again, not free.
You're paying for something that should never have been taken. That's a horrible deal that sounds more like the mafia than a healthy business practice.
Nope, you aren't right -- just a bully trying to shut people down and insult them.
I have absolutely no problem replacing a battery that degraded to the point I want it replaced; you're dishonestly trying to put that on me.
Crying about your 80 year old knees would be like crying that the battery is worn -- nobody is doing that. I haven't seen a single post saying people shouldn't have to replace degrading batteries.
iOS is secretly throttling the CPU based on "battery health" while telling the user that their battery is "healthy". You think people should magically know to replace it anyways to get back their CPU performance that they have no idea is being taken in the first place.
Your analogies and reasoning are flawed. I don't know why you're so emotionally married to Apple to treat others with such arrogance and insult.
You're right. There's no value continuing that discussion because the the physics behind this are simple.
Energy = Power x Time.
If your cell is degrading, you have less energy. There are two short term solutions
1.) Control the 'Time' component: Reduce the power and and try to achieve the 'Time' of a pristine cell. The result is a phone that's still usable throughout the day.
2.) Do not control the 'Time' component: Do not restrict the power and let the time shrink. The result is a phone that probably doesn't quite operate right because of an increased ohmic drop. The cell will produce more heat because of the increased resistance and this will further exasperate the problem. Your phone will deplete it's charge sooner but you may load your porn faster.
None of this has to do with planned obsolesce or conspiracies. I actually prefer option 1. The real solution is to just change your battery and quit whining about the inevitable. Wear items wear.

That’s what I thought you’d say. We went down that rabbit hole with my daughters iPhone 6 and repaired the screen, ear speaker, microphone and new battery. It ran like new after that on iOS 10.3.3
But now, the minute we upgraded from 10.3.3 to iOS 11.02, the built-in apps would take 4-22 seconds to load, despite multiple restores in iTunes in DFU mode. It’s useless as an every day carry phone now, even with normal geekbench scores and CPU speed, and 0% wear on the new battery.
My son, whose 6 battery was 82% and running slow as a snail, was refused a battery swap at Apple. He bought a 7+ and gave his 6 to me, and once I out in a new battery it was like new. We gave it to his sister and left it on 10.3.3, and I’m stuck trying to fix the snailPhone.
Looks like the news is now surfacing on multiple major publications.
You dont make much sense and you know that.
A phone that just shuts off at random times just needs to be repaired.
Weather that's a battery issue or other hardware fault should be rectified by the manufacturer.
Its never acceptable to just slow down my phone because the battery is bad or the battery is starting to get worn out.
If my battery needs replacement I will either charge the phone more often or pay to have the battery replaced if its not under warranty.
But Apple will not even let customers pay to have their battery replaced.
The defective batteries somehow pass their little tests and check out fine so they tell you to just buy a new iPhone.
How convenient

I know people who owns older iPhones (4s, 5) that have a smoothly software because they didnt updated the iOS from the year they went out. So that puts a different perspective besides the battery theory.
Thanks for being a voice of reason here. This story intrigues me and may just prompt me to keep my 5S going another year or two with a battery swap.
I just did a Geekbench on my old ipad mini retina and no change in performance, so this must be an iPhone thing.
My iPhone 6's performance has sucked large monkey balls for the past year. I've been putting up with it. Yeah, the battery life is crap--I MAY get up to a day, if I'm extremely lucky and don't use it at all, but it's tolerable for how much I travel.
What I didn't expect is that the slowness was coming from a degrading battery. That's like replacing your brakes and gaining 60 horsepower. Weird.
Anyhow, I'd like to see more data in this thread and less rambling.
I just ran Geekbench 4 on my iPhone 6 (non plus) to see if this is going on in my case. The answer appears to be "yes":
Single Core: 1070, Multi Core: 1806.
iPhone 6 should be getting:
Single Core: 1412, Multi Core: 2383
Time to schedule a battery replacement. Now I know why the keyboard takes 2-3 seconds to open, and the camera takes 5 seconds to load.

Thats how I feel about control center controls that actually turn off wifi and bluetooth...
possibly. My heavily used iPad Air 2 ,that is three years old with original battery, benched just fine. They also have larger batteries so it may just be a matter of time.
I'd imagine Apple will have to address this soon, at least give an explanation. Just read article on newsweek about it and cnet. So it is getting more exposure. Maybe cnn, fox , cbs and abc soon.
50 tabs in Safari? Seriously? I think my old 6+ would burst into flames. I know the wife was pretty pissed at the slowness when she used it for a few days while her 6s was waiting for parts. I know the slowness of it drove me to Android back in March. Now I know why - the battery needed replacement.

I’m saying a slow phone is better than no phone. I believe that Apple handled it badly and should have been more transparent. Like getting a notification that says “your battery is going bad, to keep your phone working, your CPU will be throttled. Please get your battery replaced”. Instead of just doing it, it looks bad and makes it hard to determine what Apple intentions are.
My iPhone 6 Plus is degraded 18% but it benchmarks 5% higher than stock models, so I don't know what's going on.
