Figures from our catalogue — this article is calculated from our catalogue. Rebuilding it does not verify prices again: open each phone page for the observation date, variant and observed or estimated status. Availability today is not guaranteed.
The point of the index is simple: compare any two phones with one number instead of reading two spec sheets side by side. Every number is computed from the manufacturer's published specs, with fixed formulas applied identically to every phone.
1 · Performance
This is anchored on the chip's tier and generation — from flagship silicon (Snapdragon Elite, Dimensity 9000-series, Apple A-series) down to entry-level parts. The chip decides how the phone handles games and heavy apps, and how many years it stays usable, so it carries the most weight in the overall index.
2 · Display
Panel class sets the base (2K, then 1.5K, then AMOLED/OLED, then FHD, then LCD), plus points for refresh rate: 144Hz above 120Hz above 90Hz. Foldable panels get a small bonus.
3 · Camera
Four inputs: main sensor resolution, the number of real lenses (not rings on the back), front camera resolution, and the chip tier — because image processing is half of modern photography. That is why two phones with identical megapixels can score differently.
4 · Battery
Capacity in mAh is the base, on a curve — the jump from 3,500 to 4,500 mAh matters far more than 6,500 to 7,500 — plus points for charging wattage.
5 · Value for money
Performance divided by the square root of the price. We use the square root rather than the raw price so the formula neither punishes flagships nor over-rewards budget phones: a 40/100 phone is not automatically 'better value' than a 90/100 phone just because it costs less.
What these numbers do not measure
These are paper ratings, not lab tests. They do not capture build quality, colour accuracy, how the battery holds up after two years, software support, or real night-time camera behaviour. Use them to narrow 3625 phones down in seconds, then read the full phone page before you decide.
A worked example: iPhone 17 Pro Max holds the highest performance index on the site (100/100), while Galaxy S22 tops value for money — which is exactly the difference between "the strongest" and "the right one for your budget".

What this analysis is based on
The figures here are computed from the Phones JO catalog itself — specifications taken from manufacturers’ official announcements, and prices from dated observation runs of OpenSooq listings for new units. This is not rewritten from other sites, and we have not tested the phones ourselves. Our method in detail ›
