The Galaxy S25 Ultra and vivo X300 Pro are premium Android phones with different hardware priorities. Samsung offers a larger, higher-resolution display and a built-in S Pen; vivo emphasizes a 200 MP ZEISS APO telephoto camera, a gimbal-grade main camera, and faster stated charging. Their specifications do not establish which phone takes better photos or lasts longer in real-world use. There is also no single reliable price difference without matching country, storage capacity, seller, and date.

Megapixel counts and manufacturer descriptions do not show which phone produces better photos or video. The cited specifications provide no independent head-to-head image or video tests, so a performance ranking would go beyond the available evidence.
Battery, charging, and regional differences
Samsung lists a 5,000 mAh battery. vivo’s stated typical capacity varies by region: 6,510 mAh outside Europe except India, and 5,440 mAh in Europe. vivo also lists 90 W wired and 40 W wireless charging. Battery capacity and charging wattage are specifications, not battery-life or charging-time test results.
