It was unclear. In any case, battery health never matters. The only aspect that matters for users is battery life (i.e., how long the device lasts). Updates worsen this.
but you implied health matters if device is updated. now you're changing the argument.
That's just a list of hardware and OS numbers. What specifically was degraded?

iPhone battery bad after installing iOS 17.5.1? Try these 7 tips
Some iPhone users are experiencing battery issues after the iOS 17.5.1 update. Here's what you can do if your phone is affected.
www.zdnet.com
"It's normal to experience a drop -- even quite a significant drop -- in battery life following the installation of an iOS update.
iPhones need to carry out a number of tasks in the background in the aftermath of an update. This consumes more battery power than usual, and the battery life will return to normal once all these extra tasks have been completed."
Performance was obliterated in some cases (most 32-bit devices, the 6 Plus), significantly affected in others (the iPhone 6s, the Mini 4, 1st-gen iPad Pros). Battery life was always severely affected. In some cases, these devices are mediocre to poor (as is the case of most 32-bit devices); in other cases, battery life was completely obliterated, with practically no meaningful screen-on time left after so many updates (as is the case of the iPhone 6s, the 1st-gen iPad Pros, and others).
Let me be extremely clear.
If the device is on its original iOS version, battery health is irrelevant to determine battery life, it will always be good.
If the device is updated, but with a new battery, battery life will be significantly worse than the original iOS version (to give an example, about 40% worse in the case of, say, the 1st-gen iPhone SE when compared to iOS 9). If the device is updated but the battery is degraded, battery life renders the device unusable (grab an iPhone 6s on iOS 15 with 70% health, and you’re lucky if you get much more than 1.5 hours of SOT with moderate use).
Apple saw that a lot of iPhone 12 owners still haven't upgraded to something newer yet, so by allowing the iPhone 12 to charge faster at 15W, they will wear out the battery faster resulting in the need to either get a replacement battery sooner or, in what is the more likely scenario, upgrade to a newer iPhone.
There. Is that what you wanted to see?
NONSENSE. It never reverts to the original iOS version afterwards, even if severe drain occurs for a little while (as the iCloud and Spotlight daemon processors run on the background (Called mdworker and mds).FYI...

These processes end, and battery life is still a lot worse. Another myth.
I feel that always depends on how big of an upgrade the next iPhone (Pro) SoC will be.
Apple can reasonably insist that all the upcoming iOS 18 generative AI and (Gemini?) Siri shenanigans rely on the (alleged) upcoming Neural Engine upgrade and thus a slew of older iPhones will either get dropped entirely this or next year, or only get to run an AI-less version of iOS 18 and iOS 19.
On the flip-side, it would probably go over better to keep most older iPhones iOS 18 and iOS 19 compatible but then frustrating users with an increasingly jarring lack of AI features which would serve as a logical and effective incentive towards upgrading to an iPhone 16 or newer.
Siri doesn't understand what your mom is saying to her and couldn't even help her if she did?
-Buy her a new iPhone with the new 32-core(?) Neural Engine!
Well no, this is not true. If you use the device for many years and never update the iOS version, the battery health eventually deteriorates. It well eventually not be good.
You can't convince me that this wouldn't have happened if not for the recent regulatory scrutiny in the past few years, both in the EU and the more recent action from Garland and the DOJ.
Not really. It was about bad communication.
Many customers thought their phone is not fast enough, not that it's just the battery replacement matter.
Planned obsolescence by Apple (another investigation ironically).
Health deteriorates, but it doesn’t impact battery life.
I do reckon there is a limit, but that limit is so far beyond that the iOS version in question is probably obsolete by then. I’ve been using my iPhone 6s on iOS 10 for almost 8 years, it’s at 60% health, and battery life is like-new. iOS 10 is far more unusable due to very sad support issues than the original battery itself.
I, unlike 99.999% of iOS users, have been using original-version devices for years. I know how this works.
then they would have announced it so that people would make sure to have the appropriate chargers to charge it faster, heating up the battery more and ruining the battery life fasterso by allowing the iPhone 12 to charge faster at 15W, they will wear out the battery faster resulting in the need to either get a replacement battery sooner or, in what is the more likely scenario, upgrade to a newer iPhone.
There. Is that what you wanted to see?
except, the temperature sensors kick in and throttle the charging speeds anyways, making 15W negligible to affecting battery health
They weren't making it worse. They were making it more stable.
As opposed to many customers realizing their phones are rebooting randomly after a few years don't feel the need to upgrade, right?
Terrible argument.
That's totally true. Software updates accelerates this. There's article about this. You can read it and then tell me how I did not read it again. (and add some "lol" on top of that please)
Newer versions of iOS are making older iPhones significantly worse in battery life and performance (when performing same task as on the older iOS). That's a fact.
Trendy updates lure apple customers into the trap of planned obsolescence
Can you recall a time when an Apple product unexpectedly shut down, froze, or ran out of battery quicker than usual? You may think that these are signs encouraging the purchase of a new one, but in reality, Apple products appear to self-destruct before its average life span of 3-5 years. This is...

I think I'm done reading your articles for you.
Also it seems you didn't read the post about the distinction between battery health and battery life, so forgive me for not believing that you finally read the articles you linked.
Obliterated? Here's an example of "obliteration" from your list...iPhone 4 running iOS 6 vs iOS 7.

Note that most of the differences between 6 and 7 are measured in fractions of a second. That's not obliterated. It's pretty typical for older hardware running newer operating systems. Think about using a 4 year old GPU with the latest PC games. They're still going to run but not as well as they do with a brand new GPU. That's just the way software works in general. It will support older hardware but it's made to showcase newer hardware.
The phones were rebooting when they reached certain battery threshold and in lower temps (i.e. winter) conditions.
You don't have to explain this issue to me. I had iPhone at that time. I knew why my phone is rebooting at 20% at -10°C. Still better experience than significant performance decrease and overall iPhone slowdown throughout the whole battery charge. Right from the 100% battery charge.
👆🏼100%. The original commenter completely misread the room, yet was cocky while communicating his flawed takeaway.
Apple has been acutely aware of the increasing scrutiny for the past at least 2 years. The filing of the DOJ case was expected and not a suprise. Apple has been prepping for their defense for a long time now, doing very minor things like this to at least have something to argue in court. Not sure small things here and there will make a difference, but good to see that we can expect continued benefits to all users as a result of the scrutiny.
Three scenarios could cause instant shutdown:
A. Battery at 80% capacity or lower.
B. Battery below 20% charge.
C. Operating battery in cold temperatures (generally freezing or lower).
So 2 out of the 3 possible scenarios could happen with a brand new battery.
Have you used any updated device? Keyboard lag, dropped frames, battery life is unusable. Also, it’s comparing it to iOS 6. I don’t care. Give me iOS 4. It’s the only comparison that matters.Obliterated? Here's an example of "obliteration" from your list...iPhone 4 running iOS 6 vs iOS 7.

The iPhone 4 is widely considered unusable on iOS 7. You giving that as an example is very telling. The iPhone 4 on iOS 7 is incredibly slow (and unusable). Also, app launch times are a fraction of the experience.
