Methodology

Spec score (algorithm v0.1)

The spec score combines four dimensions computed from normalized specifications: display (refresh rate 50 %, panel technology 30 %, size 20 %), battery (capacity 65 %, wired charging 35 %), camera (main sensor resolution 70 % on a square-root scale, plus fixed bonuses for ultrawide, telephoto, and selfie cameras), and performance (RAM 55 %, storage on a log scale 30 %, 5G 15 %). The total weighs camera and performance at 30 % each and display and battery at 20 % each.

Every metric is min–max normalized across the published catalogue, so a score of 100 means "best in this catalogue", not "perfect phone". Missing metrics reduce the dimension weight instead of counting as zero; products with insufficient data are excluded from affected rankings.

This is a specification-based proxy. Megapixels are not image quality and clock speeds are not real-world performance. The algorithm version is shown next to every score, and each product page displays the full per-dimension breakdown with its inputs.

Value score

The value score divides the spec score by the logarithm of the indicative market price and normalizes the result across the catalogue. It is currently computed only for the Czech market, where indicative prices are available; other markets follow once their price ranges are verified.
