The Samsung Galaxy S25 is the compact flagship for people who refuse to compromise on power just because they prefer a smaller phone. Launched in February 2025, it packs the Snapdragon 8 Elite chipset into a sleek 162g body that is thinner and lighter than the S24, making it one of the most pocketable high-end Android phones available. The 6.2-inch Dynamic AMOLED 2X display remains sharp and vibrant with adaptive 1-120Hz refresh rate, and Samsung has resolved the low-brightness graininess that affected the previous generation. Camera hardware carries over from the S24 with a capable 50MP main, 12MP ultrawide, and 10MP 3x telephoto setup, but the new chipset brings improved image processing and AI-powered enhancements through Galaxy AI. Battery life holds steady at a full day from the 4,000mAh cell, though charging remains at 25W wired. The real story here is the Snapdragon 8 Elite, which delivers a 37% CPU improvement and 30% GPU gain over the S24, making everything from app launches to gaming noticeably snappier. With seven years of software updates and a refined One UI experience, the Galaxy S25 is Samsung's best small flagship yet.

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.
