Samsung Galaxy S25 Ultra: The AI-Supercomputer in Your Pocket (Full 2026 Review)
I. Design: The Titanium Refinement
At first glance, the S25 Ultra seems familiar, but the changes are surgical. Samsung has moved away from the sharp, boxy corners of the S24 Ultra, opting for a subtle rounding that makes this 6.9-inch giant remarkably comfortable to hold. The frame is **Grade 5 Titanium**, which has been polished to a satin finish that resists fingerprints better than any phone I’ve tested this year.
Lighter, Slimmer, Tougher
The device is 15 grams lighter than its predecessor, weighing in at **218g**. It’s also slimmer at 8.2mm. But don’t let the slim profile fool you. With **Corning Gorilla Armor 2**, the screen is 4x more scratch-resistant and reduces glare by 75%, making it the best outdoor display in the world right now.
II. The Display: 6.9-inch Visual Masterpiece
Samsung’s displays have always set the gold standard, and the S25 Ultra pushes the boundaries even further. We are looking at a **6.9-inch Dynamic LTPO AMOLED 2X** panel with a 120Hz adaptive refresh rate.
ProScaler AI Integration
The standout feature here is **ProScaler**. This AI-based upscaling technology takes lower-resolution content (like an old YouTube video or a 1080p game) and upscales it to QHD+ in real-time. The result is a level of clarity that makes everything look native. With a peak brightness of **2,600 nits**, even the Delhi noon sun cannot wash out this screen.
III. Performance: The Snapdragon 8 Elite (Gen 4/5 Era)
Samsung has once again partnered with Qualcomm for the **Snapdragon 8 Elite for Galaxy**. This isn’t a standard chip. It features a custom Oryon CPU reaching clock speeds of **4.47 GHz**.
| Specification | Samsung Galaxy S25 Ultra Details |
|---|---|
| Processor | Snapdragon 8 Elite (3nm/2nm Class) |
| RAM | 12GB / 16GB LPDDR5X |
| Storage | 256GB / 512GB / 1TB (UFS 4.1) |
| NPU | Dedicated Gen-AI Engine (45 TOPS) |
| AnTuTu Score | 3,100,000+ (TMS Lab Test) |
During my 100-app stress test, the S25 Ultra handled everything without a single frame drop. The new vapor chamber is 2x larger, keeping the device cool even during intensive **Ray Tracing** gaming sessions. This is, without a doubt, the fastest Android phone in existence today.
IV. The Camera: A 200MP Quad-Camera Empire
Samsung’s camera strategy for 2026 focuses on "Optical Purity." The main 200MP sensor (ISOCELL HP2 Upgrade) is now backed by an improved AI Image Signal Processor (ISP).
The 50MP Ultrawide Leap
Finally! Samsung has upgraded the ultrawide lens from 12MP to **50MP**. This means your landscape shots and group photos now have the same level of detail as the main sensor. The **Dual Telephoto** system (10MP 3x and 50MP 5x) remains the best for "Space Zoom," reaching 100x with AI-clarification that actually produces usable social media photos.
V. Galaxy AI: The Now Brief & Real-Time Sync
Software is where the S25 Ultra wins. Running **One UI 7 on Android 15**, the integration of **Gemini** is seamless.
- Now Brief: A morning summary of your emails, news, and wellness data curated by AI.
- Live Translate 2.0: Now works with WhatsApp calls and 3rd party apps in real-time.
- Circle to Search: Now identifies videos and can solve complex math equations instantly.
✅ The Pros
- The most powerful chipset (Snapdragon 8 Elite).
- Upgraded 50MP Ultrawide is a game-changer.
- Lighter titanium build is much easier to handle.
- 7 years of guaranteed OS and security updates.
❌ The Cons
- Charging is still capped at 45W (Slower than Oppo/Xiaomi).
- No charger in the box (Indian variant).
- Price is premium (₹1,29,999 launch price).
VI. Battery: The 5,000mAh Marathon
While the capacity remains at **5,000mAh**, the efficiency of the 3nm/2nm chipset means the battery lasts 20% longer than the S24 Ultra. In my testing, I consistently achieved **13.5 hours of Screen-On Time**. However, the 45W charging remains a point of criticism, taking nearly 65 minutes for a full charge.
VII. Final Verdict by Tech Mobile Sathi
The Samsung Galaxy S25 Ultra is a statement. It is for the professional who needs a workstation in their pocket, the photographer who needs the best zoom, and the tech enthusiast who wants the future today. It surpasses the iPhone 17 Pro in versatility and the Pixel 10 Pro in raw power.
Final TMS Rating: 9.7 / 10
