I don’t know, but even if they were I can’t imagine it’d be easy to prove that the labels are wrong. After all, I’m not aware of any data collection on degradation or failures of batteries at the required scale and precision. And I don’t think the ratings constitute a warranty, i.e. I don’t think you’re entitled to anything if your particular phone falls short of the after the 2-year warranty expires.
But I sure would like there to be some standard that allows collecting these kinds of metrics in a way that’s privacy-preserving and can’t be fudged by manufactureres.
