The Samsung Galaxy Ultra series has set a high standard in the flagship smartphone market, with each new iteration refining and enhancing its predecessor’s capabilities. The S23 Ultra, S24 Ultra, and the latest S25 Ultra each bring unique advancements to the table. As a tech enthusiast, let’s dive deep into the details and compare these three devices to see how Samsung has evolved its premium flagship lineup.
Design & Build: Lighter Yet More Durable



The S23 Ultra introduced Gorilla Glass Victus 2 and an aluminum frame, but the S24 Ultra took a leap with a titanium frame (Grade 2), making it both stronger and slightly lighter. The S25 Ultra refines this even further with a Grade 5 titanium frame and Gorilla Armor 2 glass, improving scratch resistance and durability.
Another noticeable change is the weight reduction:
- S23 Ultra: 234g
- S24 Ultra: 232g
- S25 Ultra: 218g
Despite having a larger screen (6.9 inches vs. 6.8 inches on the S23 Ultra and S24 Ultra), the S25 Ultra manages to be thinner and lighter, making it more comfortable to hold.



Display: Brighter & More Efficient
Samsung has always been a leader in display technology, and each iteration pushes the boundaries:
- S23 Ultra: 6.8-inch Dynamic AMOLED 2X (1750 nits peak brightness)
- S24 Ultra: 6.8-inch LTPO AMOLED 2X (2600 nits peak brightness)
- S25 Ultra: 6.9-inch LTPO AMOLED 2X (2600 nits peak brightness, improved efficiency)
The jump from the S23 Ultra to the S24 Ultra was significant in terms of brightness, making outdoor visibility much better. The S25 Ultra retains the same brightness but offers better power efficiency, meaning it delivers more vibrant visuals without draining as much battery.
Performance: The Power of Snapdragon Evolution
Samsung’s partnership with Qualcomm ensures top-tier performance:
- S23 Ultra: Snapdragon 8 Gen 2 (4nm)
- S24 Ultra: Snapdragon 8 Gen 3 (4nm)
- S25 Ultra: Snapdragon 8 Elite (3nm)
With each iteration, we see a jump in CPU and GPU power. The Snapdragon 8 Elite in the S25 Ultra brings improved thermal management and higher clock speeds (4.47 GHz Oryon V2 core), making it ideal for gaming and AI-based applications.
Cameras: Refining Excellence
Samsung continues refining its camera system rather than making drastic changes:
Main Camera:
- All three models feature a 200 MP primary sensor, but the S25 Ultra improves processing and AI-based enhancements, leading to better low-light photography and sharper details.
Telephoto Zoom:



- S23 Ultra: 10 MP (3x optical) + 10 MP (10x periscope optical)
- S24 Ultra: 10 MP (3x optical) + 50 MP (5x periscope optical)
- S25 Ultra: 10 MP (3x optical) + 50 MP (5x periscope optical) (improved sensor & AI stabilization)
The periscope telephoto lens in the S25 Ultra now features AI-assisted zoom stabilization, reducing hand-shake blur.
Ultra-Wide Camera:
- S23 Ultra & S24 Ultra: 12 MP
- S25 Ultra: 50 MP (improved sharpness & dynamic range)
With a 50 MP ultrawide sensor, the S25 Ultra captures much more detail, making landscape photography more stunning than ever.
Battery & Charging: Incremental Refinements
- All three models feature a 5000mAh battery
- Charging speeds remain at 45W wired & 15W wireless
- S25 Ultra introduces Qi2.1 for improved wireless efficiency
Despite having the same battery capacity, Snapdragon 8 Elite’s efficiency and software optimizations give the S25 Ultra a longer active-use time (14h 49m vs. 13h 49m on the S24 Ultra).
Software & AI Features
The S24 Ultra introduced Samsung’s AI-driven features, such as Circle to Search and real-time translation. The S25 Ultra builds on this with:
- Best Face AI, selecting the sharpest expressions from multiple shots.
- AI-powered video enhancement, reducing noise in low-light videos.
- Extended software support: 7 major Android updates for both the S24 and S25 Ultra.

Final Verdict: Should You Upgrade?
- If you own an S23 Ultra, upgrading to the S25 Ultra makes sense for AI-powered camera improvements, better efficiency, and a stronger yet lighter build.
- If you already have an S24 Ultra, the S25 Ultra offers incremental but meaningful upgrades in weight, AI features, and battery life, but it may not be a must-have unless you need the latest AI photography tools.
For those looking to buy a flagship Samsung device, the S25 Ultra is undoubtedly the best choice, but the S24 Ultra remains an excellent value option for those who don’t need the latest cutting-edge features.
