Oh, I know it's not the point but I find it a bit disingenuous going from iPhone base model to the Pro in the last 3 years and still comparing to the base model Samsung S series. Though maybe I'm missing something non obvious.

But yeah, generally I've seen a better experience buying used phones (in good condition) instead of budget/cheap new ones.

The data is from my blog series, the latest installment of which is here:

https://infrequently.org/2025/11/performance-inequality-gap-...

The top two lines are the fastest devices available in the iOS and Android ecosystems each year, and when using Samsung S-series devices, I have made sure to pick the faster of the Qualcomm vs. Samsung Semi parts (both are used historically, but Qualcomm is most prevalent in the US). As explained in the piece, the bottom two lines are taken from representative devices in the mid-range and low-end price categories. There's wild variation in those market segments due to short-run discounting, and the most meaningful uplift in CPU speeds has coincided with 5G radios (for obvious signal-processing reasons). Because the lowest-priced segment doesn't yet feature 5G, those processors have remained stubbornly slow, even if they get cheaper every year.

Thank you for clarifying and sharing the full blog post! It was actually an error on my part because until now I didn't realize that the S-series base model and the Ultra model actually share the same CPU. I should've checked my assumptions first.

I also saw you addressed in your blog post the growing market for refurbished phones and in the last year or so I've noticed a similar thing in Romania where a e-commerce giant is involved with a company that refurbishes and resells old user devices to try and corner a big piece of the pre-owned (second-hand) market where previously you'd be stuck hunting for good deals on the national Craigslist equivalent or searching for small-ish repair shops that sold refurbished devices.
