The Samsung Galaxy S25 Ultra marks an unexpected break: by rounding its edges and erasing its corners, the Korean flagship abandons the heritage of the Galaxy Note to align itself with the design of the classic S25. And that’s not all, let’s take a look at the differences with the Galaxy S24 Ultra.
Like every year, Samsung is taking advantage of January Unpacked to renew its entire range. And like every year, the Ultra is the star. It’s the model that sells best at commercial launch, it’s the darling of Samsung fans, the best-armed of the Galaxy.

A new design that makes sense
Samsung is making a shift here. Gone are the angular edges that have characterized the Ultra range since its beginnings. The S25 Ultra adopts softer lines, more roundedwhich bring it aesthetically closer to the S25 and S25+.
A choice which could confuse early aficionados, but which is part of a logic of standardization of the range. The edges are now flatter, despite still the deformation induced by the S-Pen on the lower edge, which protrudes slightly.
This aesthetic evolution is accompanied by a welcome slimming treatment. With its 162.8 x 77.6 x 8.2 mm, the S25 Ultra is 15% thinner than its predecessor.
The difference is immediately felt in the hand, especially since the weight goes from 232 to 218 grams. A good thing, all the more remarkable since Samsung has managed to integrate a larger screen (6.9 inches versus 6.8) in the same size, thanks to further refined borders. This remains QHD and 120 Hz.
The choice of materials reflects a calculated move upmarket. The titanium frame, already present on the S24 Ultra, is now accompanied by the Gorilla Glass Armor 2 on the facade, with anti-reflective treatmentwhile Gorilla Glass Victus 2 protects the back.
Controlled power
The new Xiaomi Redmi Note 14 Pro+ is here
Xiaomi’s future bestseller has just arrived. This new reference combining impressive features and attractive prices is already on sale at Boulanger.
The integration of the Snapdragon 8 Elite across the entire range in France marks the end of an era. No more Exynos/Snapdragon distinction depending on the market: all users will benefit from the same performance. And what performances!
-The gains are significant compared to the S24 Ultra: +37% in CPU, +32% in GPU and +43% for the NPU. These figures will certainly translate into even greater fluidity on a daily basis, particularly noticeable in demanding tasks such as photo processing or gaming.
Samsung also promises an improvement to its cooling system with a 40% larger vapor chamber. What is it for? Unless it heats up less of course, which is a good thing, the Snapdragon 8 Elite is also much more efficient in this area than its predecessor.
The 12 GB of RAM in standard configuration ensures multitasking without compromise, with storage options from 256 GB to 1 TB.
Wi-Fi is still Wi-Fi 7, with support for the 6 GHz band. Which means you will be able to take full advantage of the new generation of Wi-Fi.
One downside: Samsung remains protective, the battery capacity remains fixed at 5,000 mAh. We feel that the Galaxy Note 7 affair still haunts the Korean manufacturer, Chinese manufacturers are now using batteries with a capacity of 6,500 to even 7,000 mAh and above all are switching en masse to carbon-silicon technology (smaller and more autonomous), not that Samsung does not cross.
The photo evolution that does not say its name
It is perhaps in the field of photography that the developments are the most subtle, but no less relevant.
The 200 MP (f/1.7) main sensor remains unchanged, as does the 10 MP x3 telephoto lens. The real novelty comes from the ultra wide-angle, which increases to 50 MP with an f/1.9 aperture. Samsung announces images that are 24% brighter, a welcome improvement for this type of optic that often struggles in low light.
The second 50 MP telephoto lens (f/3.4) now offers native 5x zoomwith the possibility of achieving a 10x zoom in optical quality thanks to intelligent cropping. A different approach from that of the S24 Ultra, but which should offer more versatility to demanding photographers.
Video innovations are not left out. The introduction of “space-time filter” (marketing name that hides low-light optimization technology) allows you to better manage complex scenes, especially when you need to properly expose both the background and a moving subject. LOG export will delight professional videographers, while 10-bit HDR becomes the standard (still up to 4K 60 fps).
A price positioning that does not change
Samsung maintains its price list, with an entry ticket of €1,469 for the 256 GB version. A price which remains high, but which is justified by the improvements made and the ultra high-end positioning of the device.
- 1469 euros for the 256 GB version
- 1589 euros for the 512 GB version
- 1829 euros for the 1 TB version
The classic colors (Titanium Blue, Titanium Black, Titanium Gray) are complemented by exclusive versions on samsung.com (Absolute Black, Titanium Green, Rose Gold), a now classic strategy for the manufacturer.
What we think about it
The Galaxy S25 Ultra succeeds in reinventing itself while retaining its DNA. Obviously, that’s the optimistic version.

Standardizing the design with the rest of the S25 range is a good decision that pays off: the device gains in elegance what it loses in singularity. The technical improvements, although targeted, affect the essential points: performance, photography, ergonomics. They still remain very limited.
This remains a gentle development which could disappoint those who were expecting a technological revolution. Yet it is precisely this measured approach that makes the S25 Ultra strong.
Samsung is refining its formula rather than reinventing it, with a result that should satisfy both new users and owners of older models looking to take the plunge. For those who have the Galaxy S24 Ultra, wait one or two generations before considering a change… and then again.
