Samsung’s Ultra-series has become one of the most talked-about Android flagship lines. With the Galaxy S24 Ultra already praised for its powerful performance and excellent camera, the Galaxy S25 Ultra arrived as its successor with a mix of meaningful upgrades and refinements. Here’s a simple breakdown to help you decide which one makes more sense for you in 2026.
Design and Display
Both phones share Samsung’s signature premium look with metal and glass builds, Gorilla Glass protection, and an S Pen built in.
- Galaxy S25 Ultra has a slightly larger 6.9-inch QHD+ AMOLED display compared to the S24 Ultra’s 6.8-inch panel.
- The S25 Ultra is also lighter and slightly slimmer, making it feel more comfortable in hand.
- Both offer 120Hz adaptive refresh rates, stunning brightness, and rugged durability with IP68 dust/water resistance.
Display Winner: S25 Ultra — slightly bigger and more refined, but the difference isn’t huge.
Performance and Software
Samsung upgraded the chipset in the S25 Ultra:
- Galaxy S25 Ultra uses the newer Snapdragon 8 Elite for Galaxy, which delivers noticeably better performance and stronger AI processing than the Snapdragon 8 Gen 3 in the S24 Ultra.
- Both models come with 12GB RAM and up to 1TB storage, but the S25 Ultra gets a more up-to-date software experience with Android 15 / One UI 7 out of the box, vs Android 14/One UI 6.
- S25 Ultra benefits from longer future updates since it is newer.
Performance Winner: S25 Ultra — faster chip and more future-proof software.
Camera Capabilities
Samsung’s Ultra phones are known for their versatile camera systems:
- Both phones retain a 200MP main camera and powerful telephoto lenses.
- The big change with the S25 Ultra is the upgrade in the ultrawide camera to 50MP (from the S24 Ultra’s 12MP), improving quality and detail in wide-angle shots.
- The S25 Ultra also introduces new AI-based camera features like improved low-light and audio/video enhancements.
Camera Winner: S25 Ultra — noticeably better ultrawide and smarter photo/video tools.
Battery and Charging
- Both phones include a 5,000mAh battery and similar charging speeds (around 45W wired).
- Real-world usage is similar, though optimizations with the newer chip can slightly improve efficiency on the S25 Ultra.
Battery Winner: Tie — same capacity, similar endurance.
Other Differences and Considerations
- The S25 Ultra is lighter and feels a bit more refined thanks to design tweaks and a tougher Gorilla Glass Armor 2 coating.
- Some users noted the S-Pen loses Bluetooth functions on the S25 Ultra, meaning remote camera/shutter features aren’t available (unlike the S24 Ultra).
- Prices vary, but the S25 Ultra typically launched at similar price points to the S24 Ultra, and you can often find discounts or deals on the S24 Ultra now.
Verdict: Which One Should You Buy?
✅ Buy the Galaxy S25 Ultra if:
- You want better overall performance and future software support
- You care about camera improvements, especially ultrawide shots
- You prefer a slightly larger display and lighter phone
✅ Consider the Galaxy S24 Ultra if:
- You prefer to save money by choosing a slightly older, still powerful flagship
- You value the S-Pen Bluetooth features for remote controls
- You don’t need the absolute latest chipset or camera tweaks
Quick Summary:
The S25 Ultra is the better all-around phone with notable upgrades in performance, camera, and design — making it the more future-ready flagship in 2026. However, the S24 Ultra remains an excellent buy if you’re budget-conscious and don’t need the newest enhancements.
