How is the score calculated?
Each phone gets 0–100 points in seven categories (performance, camera, battery, charging, display, build, updates), computed only from its published specs, then combined with fixed, published weights. A gap under 2.5 points counts as a tie. The performance index is an estimate based on benchmark results published at launch.
