How the value score is calculated
How the overall score compares with what is typical at the phone's price. We fit overall score against the logarithm of price across all ranked phones. A phone exactly on that line scores 50; every overall point above or below it adds or removes 2.5, capped at 0 and 100. A value score is given only when at least 3 other ranked phones cost between two-thirds and one-and-a-half times as much, so the line is never stretched far from real comparisons
The price line is fitted to the phones in our catalogue, so it moves a little as phones are added.
Worked example
The iQOO 15R costs ₹56,975. At that price the fitted line expects an overall score of 67.2. Its overall score is 80.8, which is 13.6 points above the line, so its value score is 50 + 2.5 × 13.6 = 84.
Current fit across 262 phones: expected overall score = -114.6 + 16.61 × ln(price in ₹). A phone on that line scores 50. Each overall point above or below the line adds or removes 2.5 value points, capped at 0 and 100.
