The Samsung Galaxy S25 Ultra is Samsung’s most complete flagship smartphone — and the best Android phone money can buy in 2025. Powered by the Snapdragon 8 Elite chip, a 200MP camera system, Galaxy AI built into every corner of One UI 7, and the iconic S Pen stylus, it delivers everything Samsung Galaxy fans have been waiting for.
In this comprehensive review, we cover design, cameras, Galaxy AI, performance, and the best current prices from Amazon.
Design — Titanium Frame, Gorilla Glass Armor 2
The Galaxy S25 Ultra marks the second generation of Samsung’s titanium frame — now with Gorilla Glass Armor 2 on the front and back, which Samsung claims is 2x more scratch-resistant and reduces reflections by 75% compared to regular glass. In practical use, the screen is noticeably easier to read in bright light.
The design has been refined with slightly more rounded corners than the S24 Ultra, making it more comfortable to hold despite the large 6.9-inch display. At 218g, it’s lighter than the iPhone 16 Pro Max (227g) while offering a larger screen.
Available colors: Titanium Black, Titanium Gray, Titanium Silverblue, Titanium Whitesilver
Display — 6.9″ Dynamic AMOLED 2X
The 6.9-inch display is Samsung’s best ever on a Galaxy phone. 3120 x 1440 pixels (505 ppi) is incredibly sharp, and the 1-120Hz adaptive refresh rate makes everything from social media to gaming buttery smooth. Peak brightness of 2,600 nits means direct sunlight is no obstacle — this is one of the most readable phone screens ever made.
The under-display ultrasonic fingerprint sensor is fast and accurate, and face recognition via the front camera provides a quick alternative for unlocking.
200MP Camera System — Most Versatile Zoom Ever
The Galaxy S25 Ultra features the most advanced camera system Samsung has ever put in a phone:
- 200MP main: f/1.7, sensor-shift OIS, Nona-binning for 12.5MP default output
- 50MP Ultra Wide: f/1.9, upgraded from 12MP on S24 Ultra
- 50MP 3x Telephoto: f/3.0, OIS — excellent for portraits and events
- 50MP 5x Telephoto: f/3.0, OIS — best quality 5x zoom on any phone
- 12MP Front: f/2.2 with Super HDR
The dual-telephoto setup (3x + 5x) gives you optical zoom quality at both portrait and event distances. Samsung’s AI Zoom enhances digital zoom up to 100x using generative AI — 100x still looks bad, but 30x and 50x shots are genuinely usable for the first time.
Video captures 8K at 30fps and 4K at 120fps, with improved OIS and AI-powered stabilization that rivals the iPhone 16 Pro Max.
Galaxy AI — Built Into Everything
Galaxy AI is Samsung’s answer to Apple Intelligence, and it goes deeper into the software:
- Circle to Search: Long-press nav bar and circle anything to search it instantly
- Live Translate: Real-time voice and text translation for calls and messages
- Note Assist: Auto-format, summarize, and translate Samsung Notes
- Photo Assist: Move objects, expand backgrounds, generate AI art — in Samsung Gallery, no cloud needed
- Composer: Write emails, social posts, and texts in your personal tone
- AI Select: Screen-aware actions — screenshot a recipe and it offers to set a timer; screenshot a flight and it offers to add to calendar
Galaxy AI works in Cantonese via text input on the S25 Ultra — Apple Intelligence does not.
S Pen — Still Unique
The built-in S Pen remains the S25 Ultra’s most distinctive feature. With 2.8ms latency and 4,096 levels of pressure sensitivity, it’s genuinely useful for:
- Taking handwritten notes (screen-off memo is instant)
- Annotating PDFs and documents
- Air Actions — control presentations, playback, and camera remotely
- Drawing and sketching
The S Pen slots into the phone body with a click — no charging needed for basic functions.
Performance — Snapdragon 8 Elite for Galaxy
The Snapdragon 8 Elite for Galaxy is the most powerful Android chip ever. Built on 3nm process, it delivers 45% better CPU performance and 40% better GPU performance than the S24 Ultra’s Snapdragon 8 Gen 3. In real terms: every app loads instantly, Genshin Impact runs at maximum settings with thermal headroom to spare, and 4K video editing is genuinely usable.
12GB RAM (16GB on 1TB models) keeps 20+ apps in memory. The vapor chamber cooling system is larger than the S24 Ultra, keeping performance sustained during extended gaming sessions.
Battery & Charging
5,000 mAh delivers up to 27 hours of video playback in Samsung’s testing — expect 6-8 hours of screen-on time in real use. 45W wired charging reaches 65% in 30 minutes — the fastest charging on any Samsung flagship. 15W Qi2 / 25W MagSafe wireless charging is also supported.
