The Galaxy S20 Ultra was Samsung at its most ambitious, and it is a phone best understood as a first attempt rather than a finished one. It introduced the 108MP main sensor and the 100x Space Zoom marketing that Samsung still leans on today, but the early version of that hardware had well-documented autofocus problems at launch that took several firmware updates to settle down. What has aged well is everything around the camera: a 6.9-inch 120Hz AMOLED that is still one of the largest and brightest screens you will find on a phone this old, a 5,000mAh battery, 45W wired charging and 12GB or 16GB of RAM. It is also heavy at 220g and physically enormous, with a camera bump that stops it sitting flat. In the UK it runs the Exynos 990 chip, which was noticeably less efficient than the Snapdragon version sold elsewhere. Samsung's software support window has now closed, so it no longer receives Android upgrades or security patches, which is the main reason to think twice.

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.
