Charts showing the inflation-adjusted price of iPhones declining: https://www.perfectrec.com/posts/iPhone15-price
Full table and charts are here: https://www.perfectrec.com/posts/iPhone15-price
But the take aways are: - iPhone 15 is cheapest base model since the OG iPhone in 2007 - 15 Plus is cheapest large iPhone ever - 15 Pro is cheapest pro ever (and $250 cheaper than the first Pro model, the iPhone X).
Apple may use NetPromoter internally, but on the earnings calls they are citing satisfaction surveys from 451 Research.
In 2018, they shared some of the response categories from the survey. They are customer satisfaction questions "Very Satisfied, Somewhat satisfied." Not recommendation questions.
Thank you for reading! I don't think they are manipulating the data, rather that they are surveying an unrepresentative population of tech enthusiasts, and presenting it as if representative of the entire customer base.
I'd note that other seemingly innocuous things could have an impact too. For instance, if they surveyed only people who've owned their phone for 90 days or whatnot, you would eliminate the vast majority of people who didn't like it and returned it from the sample.
99% is an extraordinary claim, which is why we think Apple should be more transparent about their methodology.
I included the Google reviews as a secondary example since it is public information. Google reviews are actually more positive on the iPhone than the third party surveys, which found satisfaction rates in the low 80s for 5G iPhones.
