This makes no sense but I still see it mindlessly repeated to exhaustion. That mention is in no way Apple specific, it’s a quality of the battery itself. Any manufacturer is in the same position, not like Apple has a monopoly on batteries that hold 80% charge after 1000 cycles.

I don’t understand how this could be measured fairly though. What kind of cycles? What temperatures was it exposed to? Charged fast or slow? This is an incomplete set of criteria, which seems designed specifically to be meaningless / gameable.

To me this seems like saying you can sell a car with a sealed gas tank as long as it “gets 40 miles per gallon.” And GM gets to decide the test course for measuring MPG, which will be a 2-mile slightly downhill coast with no stopping. Surprise! All our cars get 40-60MPG!

The unspoken implication here is that if your phone still retains 80% after 1000 cycles, then it’s probably so old and obsolete by then that battery replacement would be a silly waste of time, so why burden people with these “onerous rules” in that case.

But in reality, nothing about that metric, even if it’s true, means that customers don’t need to replace their batteries. My iPhone 15 Pro Max is in dire need of a battery replacement, at 82% after only 714 cycles. Aside from the battery, I have literally zero motivation to replace this phone. The phone manufacturers hate the idea that the battery might get replaced, because in this day and age it’s pretty much the only reason a 2 to 3-year-old phone (especially a flagship) isn’t extremely adequate for 99% of the population.
