Samsung has long dominated the premium smartphone market with its Galaxy S Ultra series, boasting cutting-edge technology, top-tier camera systems, and powerful performance. With the launch of the Samsung Galaxy S25 Ultra, expectations were high for another groundbreaking flagship. However, while the S25 Ultra certainly packs high-end specifications, its incremental upgrades over its predecessor, the S24 Ultra, raise questions about whether it truly lives up to its “Ultra” branding.
In this in-depth review, we explore the design, camera performance, AI features, battery life, and overall user experience of the Samsung Galaxy S25 Ultra to help you decide whether it’s worth the upgrade.
Design: A Subtle but Significant Shift
At first glance, the Galaxy S25 Ultra appears quite similar to its predecessor, but Samsung has made some subtle yet notable design changes. One of the biggest differences is the transition from sharp edges to a more rounded frame with flat edges, making the phone feel more comfortable in hand.
While this change enhances usability, it also makes the Ultra model less distinctive compared to the standard Galaxy S25 and S25+. Some users may prefer the bold, squared-off look of previous Ultra models, but Samsung’s decision to soften the design aligns with the aesthetics of the rest of the S25 lineup.
The build quality remains premium, featuring Gorilla Glass Armor on the front and back, with an aluminum frame for added durability. Despite a lighter and slightly thinner body, the phone retains IP68 water and dust resistance.
S Pen: A Downgrade in Functionality
One of the biggest disappointments with the S25 Ultra is the removal of Bluetooth functionality from the S Pen. Unlike previous Ultra models, which allowed users to use the S Pen as a remote control for photos, presentations, and media playback, the new S Pen now functions only as a standard stylus.
For power users who frequently relied on the Bluetooth-powered features, this feels like a step backward. While the S Pen still offers precise input, low latency, and excellent note-taking capabilities, the loss of remote-control functions makes it less versatile than before.
Display: Still One of the Best, but Not a Game-Changer
Samsung is known for its industry-leading displays, and the S25 Ultra continues to uphold that reputation. The phone features a 6.8-inch Dynamic AMOLED 2X panel with a WQHD+ resolution (1440p) and an adaptive 120Hz refresh rate.
What’s New?
- Increased peak brightness of 2,600 nits, making outdoor visibility even better.
- Improved eye comfort features that reduce blue light strain.
- New anti-glare coating, reducing reflections in bright environments.
While the S25 Ultra’s display remains one of the best on any smartphone, the improvements are minor compared to last year’s S24 Ultra. If you’re coming from an older Samsung device, you’ll appreciate the ultra-smooth scrolling, deep blacks, and vibrant colors, but for S24 Ultra users, the difference is marginal.
Cameras: Refining an Already Strong System
Samsung’s Ultra models are known for powerful camera systems, and the S25 Ultra makes subtle but effective improvements.
Camera Setup:
- 200MP primary sensor (same as S24 Ultra)
- 50MP ultrawide sensor (upgraded from 12MP)
- 50MP 5x telephoto lens
- 10MP 3x telephoto lens
- 12MP front-facing camera
Key Camera Upgrades:
- New 50MP ultrawide sensor: Improves low-light performance and macro photography.
- Refined image processing: AI-powered enhancements for better detail and dynamic range.
- 5x telephoto lens replaces the old 10x lens: While 10x optical zoom is gone, the new 50MP 5x sensor captures sharper, more detailed zoom shots, thanks to AI-powered zoom processing.
- Improved night mode: Samsung’s Nightography feature now produces clearer, less noisy low-light photos.
While the main 200MP sensor remains unchanged, the processing improvements make a noticeable difference in image quality. However, for users upgrading from the S24 Ultra, the changes might not be drastic enough to warrant a switch.
AI Features: Hype vs. Reality
One of the biggest talking points of the S25 Ultra is Samsung’s push towards AI-powered features, powered by Google’s Gemini AI. However, real-world performance suggests that Samsung’s AI is still in its early stages and not as groundbreaking as expected.
AI Features on the S25 Ultra:
- Live Translate: Real-time call translations in multiple languages.
- Generative AI Photo Editing: Smart object removal and background editing.
- AI-assisted Notes and Summaries: Auto-generates meeting summaries and action items.
The Problem?
Many of these AI features feel half-baked, with occasional errors and inconsistencies. The Live Translate feature can be hit-or-miss, and while AI-powered photo editing is impressive, it doesn’t significantly outperform existing tools.
For now, AI on the S25 Ultra feels more like a gimmick than a true game-changer. If you’re expecting revolutionary AI capabilities, you may be disappointed.
Performance and Battery Life: Still a Powerhouse
The Galaxy S25 Ultra is powered by the Qualcomm Snapdragon 8 Gen 3 for Galaxy, paired with 12GB or 16GB of RAM and storage options up to 1TB.
Performance Highlights:
- Lightning-fast app performance and seamless multitasking.
- Improved GPU for gaming, with better efficiency and thermal management.
- Samsung’s One UI 6.1 provides a smooth and customizable experience.
Battery Life: No Major Improvements
- 5,000mAh battery (same as S24 Ultra)
- 45W fast charging (no upgrade)
- Wireless charging and reverse wireless charging remain
Despite having a more efficient chipset, the battery life is almost identical to the S24 Ultra. You’ll still get a full day of heavy usage, but don’t expect any significant leaps in longevity.
Verdict: Is the Samsung Galaxy S25 Ultra Worth It?
The Samsung Galaxy S25 Ultra is an excellent flagship phone, offering a refined design, powerful performance, and a great camera system. However, the lack of major innovations makes it less exciting than previous Ultra models.
Who Should Buy It?
✅ Upgrading from an older device (S22 Ultra or older) – You’ll see a big jump in performance, camera quality, and display technology.
✅ Power users who need a top-tier Android experience – It’s still one of the best smartphones available today.
Who Should Skip It?
❌ S24 Ultra users – The upgrades are too minor to justify switching.
❌ S Pen enthusiasts – The loss of Bluetooth features makes it less useful.
❌ Users expecting revolutionary AI – The AI features are not yet mature enough to be a major selling point.
Final Score: 8.5/10
The S25 Ultra is still one of the best Android smartphones on the market, but without any groundbreaking features, it feels more like an “S24 Ultra+” than a truly new generation Ultra phone.
