The Galaxy A51 5G was Samsung's move to make 5G ordinary rather than a flagship luxury. It took the hugely popular A51 formula and swapped in an Exynos 980 chip with a built-in 5G modem, so mid-range buyers got network speeds that had previously been reserved for the S series. What carried the phone was the screen: a 6.5-inch Super AMOLED panel with proper contrast and deep blacks, which is still noticeably better than the LCDs used by budget rivals. Samsung also kept the practical touches, including a 3.5mm headphone jack and a microSD slot alongside the 128GB of built-in storage. The compromises show up elsewhere. The display runs at a standard 60Hz, charging tops out at a leisurely 15W, and the quad camera leans on 5MP macro and depth sensors that add little beyond a longer spec list. There is no official water resistance rating either. Its Android update window has now closed, so this is a phone for light use rather than a long-term daily driver.

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.
