Because cars don't lose 1/3rd of horsepower after 2-3 years due to manufacturer ECU being programmed to slow them down. A maintained car will lose less then 10% of its horsepower due to wear and tear over 150.000miles / 10 years. Note that I said "well maintained" - meaning there's a way to maintain the car to keep the advertised performance. There is no way to "maintain" iPhones to keep their performance over three years - the battery will degrade and Apple will silently make your phone slower than advertised. This is a world of difference from losing 1/3rd of performance due to software hardcoded loss to push new sales. Intent and reason for degradation matters.

    If you know that the battery is at fault (Apple hid that) and if Apple Store will replace it (they refused it for many people because diagnostics doesn't show an issue even if phone is throttled). Apple is also actively fighting and lobbying against any kind of legislation that makes electronics repairable and maintainable. Read up on the issue a bit more :)

(Note that Apple basically never refuses to replace a battery if you pay the $79. They will, occasionally, quibble about the 80% requirement for an in-warranty replacement.) I agree that Apple should be better about communicating that batteries should be replaced after a couple years of use. My objection is to the claim that there is "no way to maintain iPhones".

No, stop it. Great paper[1] by Ruhr University students. Whole research is great so take time to check it out, if you want to see bloody industry. Notable pages: 8, 17, 18 for rev. eng maps. https://cseweb.ucsd.edu/~klevchen/diesel-sp17.pdf https://cseweb.ucsd.edu/~klevchen/diesel-sp17.pdf
