The Xiaomi 15 is the rare modern flagship that stays genuinely small. At 6.36 inches and 191g it is one of the few phones with top-end silicon that you can still use one-handed, and Xiaomi has not thinned out the specification to achieve it. The Snapdragon 8 Elite inside is the same chip powering far larger rivals, and the 5,240mAh battery is bigger than the one in the Xiaomi 14 despite the identical footprint, which is the single most useful change this generation. Charging is quick enough that battery anxiety rarely arises, with 90W wired and 50W wireless both supported. The Leica-tuned triple 50MP camera array is the other reason to look here: main, ultrawide and telephoto all use 50MP sensors, so image quality holds up when you switch lenses rather than collapsing on the secondary cameras as it does on most compact phones. Trade-offs are the ones you would expect, namely no microSD, no headphone jack and a screen that keen video watchers may find cramped.

Based on calibrated CPU benchmark rankings (60%) and GFXBench GPU scores (40%). Apple chipsets included via editorial calibration since AnTuTu under-represents Apple's architecture.
Based on panel type (LTPO is the modern flagship gold standard), resolution, refresh rate, peak brightness, screen size, and HDR10+ / Dolby Vision support. Marketing peak-brightness claims are capped at 3500 nits to prevent inflation.
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 selfie megapixels and max selfie-video resolution.
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.
