9 refurbished deals available - SIM-free from £91.00.
The Samsung Galaxy S8 is the phone that introduced the curved, almost bezel-free Infinity Display look Samsung has used ever since, and nearly a decade after its April 2017 launch it still looks modern in a way most phones of that era do not. The 5.8-inch screen sits in a body narrower than many of today's compact phones, which makes it one of the easiest large-screen handsets to use one-handed. Samsung also loaded it with hardware that has since disappeared from the range: a headphone jack, microSD expansion, an iris scanner and a dedicated Bixby button. As a purchase today it is strictly a cheap secondhand or backup phone. The 3,000mAh battery was modest even in 2017 and will have lost capacity, the Exynos 8895 shows its age when apps get demanding, and software support ended with Android 9 Pie back in 2019, so there are no security patches. The single 12MP camera is still pleasant in daylight but has none of the computational processing that transformed phone photography afterwards. Buy it for the design and the price, not the performance.

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 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.
