Intro

The Samsung Galaxy S25 Ultra is Samsung’s 2025 flagship aimed at professionals, creators and enthusiasts who want the absolute best in display, camera, performance and AI features. Launched alongside the S25 series, the S25 Ultra refines Samsung’s Ultra formula with a titanium frame, a more advanced imaging pipeline and deeper on‑device AI

What’s new (Quick TL;DR)

• Titanium frame + Gorilla Armor 2 for improved durability. Samsung

• 6.9″ QHD+ LTPO Dynamic AMOLED 2X, 1–120Hz adaptive refresh. Samsung Mobile Press

• Snapdragon 8 Elite for Galaxy (customized 3 nm variant for Galaxy). Samsung

• 200MP main camera + new ProVisual processing and Galaxy AI image features. Samsung Mobile Press

• 5000mAh battery with 45W wired fast charging and wireless charging. Samsung

Display

The S25 Ultra sports a 6.9‑inch QHD+ Dynamic LTPO AMOLED 2X panel with an adaptive 1–120Hz refresh range, HDR10+ support and a peak brightness designed for outdoor legibility. Color accuracy out of the box is very good and the panel includes Samsung’s Vision Booster and ProScaler upscaling for low‑resolution content. Peak brightness and adaptive modes make it one of the brightest mainstream phones. Samsung Mobile Press+1

Design & Build

The phone moves to a titanium frame for the chassis with Gorilla Armor 2 glass and IP68 water/dust resistance. The Ultra keeps a large slab form but has slightly reduced bezels and a rounded aesthetic for improved hand comfort. Dimensions are roughly 162.8 × 77.6 × 8.2 mm and weight ~218 g.

Performance & SoC

Samsung ships the S25 Ultra globally with the Snapdragon 8 Elite for Galaxy — a 3 nm custom variant with high‑performance cores and enhanced AI/graphics acceleration (ray tracing support in games, Vulkan optimizations). This SoC plus up to 12 GB RAM and UFS storage means top‑tier benchmark scores, smooth multitasking, and improved thermals from a larger vapor chamber and new TIM (thermal interface material). Samsung+1


Cameras & Imaging

The S25 Ultra features a multi‑module camera system built for flexibility:

  • 200 MP main sensor (wide) with OIS — extreme detail capture and pixel binning for low light. Samsung Mobile Press

  • 50 MP ultra‑wide (new 50MP UW on Ultra model) for high‑resolution wide shots. Samsung Mobile Press

  • 10 MP telephoto (3× optical) and 50 MP telephoto (5× optical) — dual tele lenses for clean optical zoom ranges and hybrid zoom up to Space Zoom limits. Samsung Mobile Press

  • Front: 12 MP selfie camera with portrait improvements via AI.

Video: up to 8K @ 30fps and 4K @ 60fps with improved Nightography and object/lighting detection from the ProVisual engine. Galaxy AI features such as Audio Eraser, Object‑Aware Engine and other computational tools help clean and enhance photos and clips. Samsung Mobile Press+1

Battery & Charging

Battery capacity is 5000 mAh. Samsung rates extended video playback and day‑long real usage; the phone supports 45W wired Super Fast Charging, 15W wireless charging, and Wireless PowerShare for reverse wireless charging of accessories. Real world charge times depend on charger and thermal conditions but 45W gives useful top‑ups quickly. Samsung

Software & AI

Ships with Android 15 + One UI 7 and deep Galaxy AI integration (Now Brief, Cross‑App Action, on‑device multimodal assistants). The S25 Ultra is designed to offload many AI tasks on the device to reduce latency and privacy exposure. Samsung announced wide language support for Gemini/AI features at launch. Samsung Newsroom+1


Audio, Haptics & Extras

• Stereo speakers tuned for Dolby Atmos.

• Under‑display ultrasonic fingerprint reader, enhanced 3D face recognition mechanisms for unlocking.

• Built‑in S Pen with low latency — great for note taking and editing.

• Expandable meaning: no microSD slot (storage choices up to 1TB). Samsung

Photography Notes (practical)

• 200MP is great for daylight detail but typical outputs use pixel‑binning to 12–50MP for noise control.

• The dual telephoto approach yields superior mid‑range zoom quality vs single tele approaches.

• Nightography improvements and the improved AP help video low‑light capture noticeably
