Apple has no chance to claim their batteries can have 80% capacity after 1000 cycles seeing how they never achieved this so far. Lying about it puts them in a world of mass recalls and fraud investigations.

Depends on how "cycle" is defined - I'm sure they can finagle it so "any charge added to the battery" counts as a cycle.
As a datapoint my iPhone reports 522 cycles and 89% max - from march 2024. I do use the "limit charging to 80%" feature which I suspect may become mandatory before 2027 ...

The definition is pretty well established, and Apple themselves have for years used it consistently.

> You complete one charge cycle when you’ve used (discharged) an amount that represents 100% of your battery’s capacity* — but not necessarily all from one charge. For instance, you might use 75% of your battery’s capacity one day, then recharge it fully overnight. If you use 25% the next day, you will have discharged a total of 100%, and the two days will add up to one charge cycle. It could take several days to complete a cycle.

the definition of a battery cycle is very well established. there isnt really any room to finagle it.
Charging to 80% significantly decreases the wear. Your battery would be way lower if you charged to 100%
I don’t think “a cycle” is up for redefining. I hope these terms are defined in the law.
But that supports my assumption that realistically the batteries don’t last 1000 cycles even when charged conservatively. The last 9% will go faster than the first 11%, the battery already has lower capacity and needs to be charged even more often.
On the other hand if I only get to 1000 cycles by charging up to 80% then I’m not getting 100% of the battery, am I?
Dieselgate was caught by some dudes with an emissions measuring device. It’s not that extreme to get a number of iPhone batteries, test them to 1000 cycles and see if statistically they still retain 80% capacity. If they don’t Apple could be looking at replacing everyone’s batteries.
The obvious solution is underrating - just like a 1 TB SSD actually has more than 1TB of "raw storage" available internally. What is a 100% battery today will be sold as an 80% capacity tomorrow, with 20% "overage" available for wear.
That’s fine as long as the battery ends up having 80% real capacity after 1000 cycles and maybe Apple is also transparent about how.
A bigger issue which I don’t know if the law covers is with the other battery specs. An 80% battery that can’t handle any spikes (low power mode) is useless.
The easiest is to just require it be replaced under warranty - if the battery has to be usable to 1000 cycles, and it is at 80% and 999 cycles but doesn't "work" it's a warranty replacement.
But that then brings in a "how many years" question.
I'm pretty the spec sheet claimed 1000 cycles when I bought my iPhone 17.
They do claim it at least for iPhone 15 "under ideal conditions": https://support.apple.com/en-us/101575
VW engine specs said some things about emissions. It’s fine to have unrealistic specs if there are no consequences. The f there’s a law about it they’re far more exposed to people catching a lie or at least an unrealistic estimate.
