Eventually all batteries do that. How the batteries are (mis)used controls
how soon that happens.

I can't imagine you're suggesting that all worn out batteries be replaced
for free, so where would *you* draw the line?

That's an easy one... when they wear out in the warranty period, replace
them as defective.

they didn't wear out.

the batteries work perfectly fine in normal everyday use.

only the absolute maximum was limited, and only slightly.

So they don't work "fine". My understanding is if Apple didn't install
software to throttle the CPU the battery would cause the phone to shutdown.
That's not working "perfectly fine".


But it may go beyond that since this is clearly a design
flaw.

it's not a design flaw and affects all devices that use batteries. it's
a limitation of today's battery technology.

it's also not just apple. here's one example of many:

https://www.engadget.com/2017/04/21/...google-huawei-
over-nexus-6p-battery-issues/
A federal class action complaint has been filed accusing Google and
Huawei of fraud, breaching warranty and improperly handling customer
complaints after a number of Nexus 6P smartphones unexpectedly shut
down and became trapped in "boot loop" cycles.
....
The Nexus 6P hit the market in late 2015. It's a $500 smartphone with
a 5.7 inch screen that was, overall, a welcome improvement over the
previous year's Nexus 6. As long as it didn't suddenly shut off with
full battery, that is.
....
The Nexus 6P joins a handful of other past-gen Android phones
embroiled in lawsuits over dysfunctional devices, including LG's G4,
V10, G5, V20 and even the Nexus 5X.

You clearly don't understand the technology. If Apple had known of the
problem when they designed the phone they would have used a larger battery
with a higher maximum current. Then as it wore it would still power the
phone at 100% capacity past the end of the warranty period.
