Short summary: The S25 Ultra is an iterative but meaningful upgrade over the S24 Ultra — faster chipset, a slightly bigger/brighter display, improved ultrawide camera, lighter body and newer software/AI features. The S24 Ultra remains an excellent value if you find it discounted.

๐งญ Design & Display — small changes, nicer feel
Both phones keep Samsung’s premium design DNA: metal frame, glass front and back, and S Pen support. The S25 Ultra is slightly slimmer, a touch lighter and reduces bezels compared to the S24 Ultra — giving a cleaner look and a slightly larger 6.9″ canvas for multimedia. If you prefer the biggest possible screen for reading, photos and productivity, the S25 Ultra pulls ahead here.
Verdict (Design/Display): S25 Ultra wins by a narrow margin — more screen, smaller bezels and better ergonomics.
⚡ Performance — S25 Ultra = faster and more efficient
The major internal jump is the Snapdragon 8 Elite for Galaxy in the S25 Ultra (3nm). Compared to the S24 Ultra’s Snapdragon 8 Gen 3, the S25 Ultra offers noticeably better sustained performance, improved GPU throughput for gaming, and stronger on-device AI compute for camera and assistant features. In practice this means smoother gaming at high settings, quicker AI tasks (photo edits, on-device transcriptions), and lower thermal throttling under heavy loads.
Verdict (Performance): Clear S25 Ultra advantage — choose it if you game a lot or plan to keep the phone 3–5 years.
๐ท Cameras — hardware stability, software polish (big ultrawide upgrade)
Hardware wise both share the same headline: a 200 MP main camera and powerful zoom telephoto/periscope modules. The S25 Ultra’s notable camera change is the upgraded ultrawide sensor (50 MP on S25 Ultra) which improves detail and low-light wide-angle shots; beyond that Samsung focused on refined image processing and Galaxy AI improvements (better night mode, improved HDR, smarter subject separation). For zoom and portrait work the two phones are very close; for landscapes and group shots the S25 Ultra shows clearer ultrawide images.
Photo quick-take:
-
Daylight main camera — both excellent (lots of detail).
-
Ultrawide — S25 Ultra sharper and more detailed.
Telephoto / periscope zoom — similar hardware, so similar results in most conditions.
Verdict (Camera): S25 Ultra edges out due to the better ultrawide and refined processing — but heavy zoom users won’t see a dramatic difference.
๐ Battery & Charging — familiar but efficient
Both phones use a 5,000 mAh battery and the same wired/wireless charging speeds (45W wired, ~15W wireless). The S25 Ultra’s newer chipset and efficiency gains translate to slightly better real-world endurance, but you shouldn’t expect major battery-capacity differences. If battery top-up speed matters, note there’s no big jump in charging wattage this generation.
Verdict (Battery): Tie — S25 Ultra has better efficiency, but capacity and charging specs are unchanged.
๐ง Software & AI — S25 Ultra ships newer features
S25 Ultra ships with Android 15 + One UI 7 and fresh Galaxy AI features (on-device assistant improvements, smarter photo tools, system-wide generative capabilities). Samsung’s update policy for the S25 series also promises long-term OS and security support, making S25 a safer pick if you keep phones for many years. S24 Ultra remains well-supported but S25 wins on the “new-features-first” front.
Verdict (Software): S25 Ultra — better out-of-box software and longer future-proofing.
๐ธ Price & Value — S24 Ultra becomes the value king
At launch the S25 Ultra carries the price premium of a new flagship. The S24 Ultra, after the S25 release, tends to get price cuts and deals — making it the better value if you want flagship cameras and display without newest silicon. If price is important and you don’t need the absolute best ultrawide or marginal performance uplift, an S24 Ultra deal is a smart buy.
Verdict (Value): S24 Ultra for value shoppers; S25 Ultra for those wanting the newest tech and longer updates.
