Based on main-sensor size (1-inch / 1/1.3" beats 1/2.0"), telephoto reach (periscope > 5x > 3x optical), image processing tier (Apple Pro, Pixel Pro, Galaxy Ultra, Honor Magic Pro, Xiaomi Ultra), pro video features (ProRes, Apple Log, Dolby Vision), camera-partnership branding (Leica, Hasselblad, Zeiss) and OIS. Older flagships are de-rated since image processing pipelines have advanced significantly each generation. Megapixel count is deliberately downweighted — it correlates poorly with real-world camera quality.

Based on battery capacity (mAh) adjusted for platform efficiency calibrated against NotebookCheck, Tom's Guide, GSMArena and CNET reviewer tests. Apple A-series gets +45% (iOS process freezing + LTPO 1Hz + tuned panels make iPhone Pro Max outlast many 6500+ mAh Android phones in measured tests). Top Snapdragon / Dimensity flagships get +15%, budget chipsets are penalised −15% to −25% to reflect less efficient displays and looser background limits. Charging speed is excluded — see the separate Fast charging tag for that.
