Intro
The newest Galaxy S25 Ultra and Galaxy S25 Plus are here, and Samsung's top and mid-sized flagships have never been closer to one another in terms of specs and features!
While each model has its audience, the spotlight inevitably falls on the Ultra model, Samsung’s crown jewel, packed with cutting-edge tech and premium features. It surely has the upper hand in some aspects, but it's also true that the Galaxy S25 Plus is just a smidgen less impressive, but also more affordable, making it excellent value.
Yes, the Galaxy S25 Plus shouldn’t be underestimated. Positioned as the middle child in the lineup, it promises an appealing blend of performance, size, and value. Naturally, this raises the question: how does the Ultra, with all its grandeur, stack up against it more affordable peer?

A cohesive design language (Image by PhoneArena)
The Galaxy S25 Ultra has scored a pretty substantial redesign. Gone are the straight edges at the bottom that form a nearly perfect right angle. In their stead, the Galaxy S25 Ultra has curved corners. As a result, both the Galaxy S25 Ultra and Galaxy S25 Plus now utilize the same design language, which is delivering a level of aesthetic consistency unseen before in the Galaxy S lineup.
Aside from this change, things haven't changed much: the Galaxy S25 Ultra still relies on titanium for the frame, just like the Galaxy S24 Ultra, while the front and rear plates use Corning's Gorilla Glass Armor 2, with Samsung's anti-reflective coating on.

At the same time, the Galaxy S25 Plus still relies on Samsung's Armor Aluminum for the frame and Gorilla Glass Victus 2 for the glass panels. No anti-reflective coating here.
Aside from the shape change, the Galaxy S25 Ultra comes with flat front and back Gorilla Glass Armor 2 panels, the beloved S Pen Stylus, IP68 water- and dust-resistance, as well as the titanium frame that was introduced last year.
The titanium-clad Galaxy S25 Ultra also employ slimmer bezels in comparison with the Galaxy S25 Plus, which has allowed Samsung to actually deliver a slightly larger display on the Ultra, which now measures 6.9 inches across. The Galaxy S25 Plus skips this design change and doesn't come with a larger screen.
Size-wise, the Galaxy S25 Ultra is naturally the larger device, but it's worth noting that both phones are significantly more compact than their predecessors. The Galaxy S25 Ultra has been slimmed down to 8.2mm and 218gr, while the Galaxy S25 Plus measures 7.3mm thin and 190gr. Extraordinary!
The ubiquitous S Pen is once again making the rounds on the Galaxy S25 Ultra as well, while the Galaxy S25 Plus naturally doesn't get this extra.
Both the Galaxy S25 Ultra and Galaxy S25 Plus employ the same flat design style with a single display punch hole for the camera. IP68 water and dust resistance are available on both the Galaxy S25 Plus and Galaxy S25 Ultra. No extra buttons here, these are not iPhones!
In terms of colors, the Galaxy S25 Ultra will come in Black, Gray, Silver Blue, White Silver, while the Galaxy S25 Plus will sell in Navy, Ice Blue, Silver Shadow, and Mint colors. We expect some exclusive hues to be available on Samsung.com.
Colors-wise, the Galaxy S25 Ultra is available in Titanium Silverblue, Titanium Black, Titanium Whitesilver and Titanium Gray, while the Galaxy S25 Plus comes in Navy, Silver Shadow, Icyblue, and Mint. As usual, we expect some cool exclusive colors to be available on Samsung.com.

Thanks to some pretty excessive bezel-slimming, we get a larger 6.9-inch Dynamic AMOLED 2X display, with HDR support, super-smooth 1-120Hz refresh rate, as well as the useful anti-reflective coating which minimizes glare passively The peak brightness remains at 2,600 nits, just as much as the previous Galaxy S24 Ultra, so no bump in this vital area.
The Galaxy S25 Plus also get a 2,600-nit display, but the size remains consistent with last year's phone, it's a 6.7-inch Dynamic AMOLED 2X display at the front with HDR support, QHD+ resolution, and super-smooth 1-120Hz refresh rate. Sadly, we get no anti-reflective coating here, as that remains a staple of the Ultra flagship. And the latter is probably one of the most significant differences between the two devices: you will definitely notice it if using the two side-by-side under very bright lighting.

Our in-house tests reveal that both have pretty identical screens in terms of properties. Both phones achieve similar maximum and minimum brightness levels, as well as nearly perfect color temperatures, contrast, and overall accuracy. As usual with Samsung screens, both displays are a joy to use and gawk at.
The CIE 1931 xy color gamut chart represents the set(area)of colors that a display can reproduce,with the sRGB colorspace(the highlighted triangle)serving as reference.The chart also provides a visual representation of a display's color accuracy. The small squares across the boundaries of the triangle are the reference points for the various colors, while the small dots are the actual measurements. Ideally, each dot should be positioned on top of its respective square. The 'x:CIE31' and 'y:CIE31' values in the table below the chart indicate the position of each measurement on the chart. 'Y' shows the luminance (in nits) of each measured color, while 'Target Y' is the desired luminance level for that color. Finally, 'ΔE 2000' is the Delta E value of the measured color. Delta E values of below 2 are ideal.
The Color accuracy chart gives an idea of how close a display's measured colors are to their referential values. The first line holds the measured (actual) colors, while the second line holds the reference (target) colors. The closer the actual colors are to the target ones, the better.
The Grayscale accuracy chart shows whether a display has a correct white balance(balance between red,green and blue)across different levels of grey(from dark to bright).The closer the Actual colors are to the Target ones,the better.
Samsung has partnered up with its TV division to bring a pretty decent new feature to all its flagships. There's a new ProScaler feature that enables content upscaling and promises up to 40% less artifacts when viewing low-res videos on your phone.
We tested either display against the older model but didn't really notice a major difference in terms of overall quality on the new screens, so don't think this upscaling feature will magically fix your low-res content woes.
Biometrics-wise, both devices come with the standard ultrasonic fingerprint scanner built right into the display, and a picture-based face unlock. Both work pretty well, with accurate and quick readings and subsequent unlocking. No issues here.
Performance and Software
Qualcomm's finest on board
Excellent performance! (Image by PhoneArena)
Both the Galaxy S25 Ultra and the Galaxy S25 Plus come with the Snapdragon 8 Elite for Galaxy chip, an overclocked and fine-tuned 3nm chipset, a first for Samsung. Fortunately, the company will be outfitting all Galaxy S25 devices in all regions with this Snapdragon chip, which will deliver uniformity in terms of performance and features across the board.
With the Snapdragon 8 Elite for Galaxy, Samsung promises 37% CPU and 30% GPU performance increase, as well as 40% improvement in NPU performance for on-device AI calculations.
With the Galaxy S25 Ultra and Galaxy S25 Plus, we get truly superb performance, both in real-life and in synthetics benchmarks. In the CPU-tasking Geekbench 6 and the GPU-heavy 3DMark Extreme tests, both the Galaxy 25 Ultra and Galaxy S25 Plus perform admirably, beating all of their closest current competitors, the iPhone included. Either of Samsung's new phones feel extremely responsive, especially when compared with previous Galaxy S releases.
We can't say that the Galaxy S25 Ultra feels faster than the Galaxy S25 Plus, but the effect of the larger vapor chamber on the Galaxy S25 Ultra can be felt. In the "low" 3DMark Extreme graphics test, which shows what the overall graphics performance is when the phone throttles after a lengthier gaming session, it's the Galaxy S25 Ultra that scores a higher total score. This essentially makes it a better buy for avid mobile gamers.
While it may sound that the Galaxy S25 Ultra and Galaxy S25 Plus will have similar performance, the reality is that the Galaxy S25 Ultra will certainly come up on top due to a much larger vapor chamber inside, which will dissipate heat more efficiently than the Galaxy S25 Plus and theoretically deliver better performance.
Both phones arrive with 12GB of RAM in all storage variants, which are 256GB, 512GB, and 1TB for the Galaxy S25 Ultra, while the Galaxy S25 Plus comes with 256GB and 512GB variants.
Software
Both devices come with One UI 7, which is based on Android 15 and comes with some significant visual and functional changes that elevate the overall user experience. You can read more about it in our One UI 7 preview right here.
Samsung has introduced some pretty big new additions to Galaxy AI. The standout feature here is the Gemini-powered cross-app actions, enabling the on-device AI to interact with multiple apps and perform cross-app tasks based on a single natural-language request. For instance, you can ask your Galaxy to find your favorite sports team’s schedule and automatically add each game to your calendar, complete with reminders.
The Now Bar, located at the bottom of the lock screen, can show different live activities, the charging status of your phone, a small music playback widget, and so on.
It's Google’s Gemini that is at the core of these enhancements, along with the improved Circle to Search feature which now has "Action Chips". Those are smart and interactive shortcuts to relevant phone functions. For example, circling a phone number allows you to call it instantly, while circling an address lets you navigate to it via Google Maps—making these interactions faster and more intuitive.
Both devices will get seven years of major software updates––those two Galaxies will be supported until 2032.

The Ultra is making moves
Only the Galaxy S25 Ultra can pride itself with a major camera hardware change (Image by PhoneArena)
With the Galaxy S25 Ultra, we get few changes in hardware. The same 200MP main camera, 50MP telephoto with 5X zoom, and 10MP 3X telephoto cameras are making the rounds; new here is a 50MP ultrawide camera, an upgrade from the 12MP on the Galaxy S24 Ultra.
Despite the specs bump, we still expect the camera to output pixel-binned 12MP photos with superior sharpness and low-light performance. Sadly, this upgrade isn't slated for the Galaxy S25 Plus.
Meanwhile, the Galaxy S25 Plus once again comes with the same setup as most of its immediate predecessors: a 50MP main camera, a 12MP ultrawide, and a 10MP 3X telephoto. It's definitely starting to be a little stale, and judging from the results of our in-house camera tests, it's the

A common new feature on both new phones is actually embedded into the Snapdragon 8 Elite for Galaxy chipset, which comes with a new ProVisual Engine, the backbone of the software image-processing that's largely responsible for how photos and videos turn out. The new engine brings updated image-processing algorithms, which reportedly produce photos with less noise and motion blur, as well as better details. Cool!
Other changes include a new Virtual Aperture feature in the Expert RAW camera mode which allows F1.4 to F14, giving you greater control over background blur and sharpness for more customized shots.
Video recording has also seen notable improvements. Both the Galaxy S25 Ultra and Galaxy S25 Plus score upgrades from 8-bit HDR to 10-bit HDR video capture, delivering richer colors and enhanced dynamic range. Additionally, the introduction of Galaxy Log video capture allows for greater flexibility in color grading during post-processing.
On-device AI has been harnessed for the new Audio Eraser tool, which lets you control six different types of sounds in your videos. This makes it possible to isolate or enhance specific sounds while minimizing unwanted background noise.
Generative edits and the object eraser have also been refined to ensure cleaner results, eliminating the creation of unwanted artifacts during edits.
Battery Life and Charging
Once again… no changes
… but the battery life will be better, right? Right? (Image by PhoneArena)
Both the Galaxy S25 Ultra and Galaxy S25 Plus boast the same batteries as their predecessors, 5,000mAh and 4,900mAh, respectively. Just a tiny difference between the two phones, which speaks rather well for the Galaxy S25 Plus, which should be more or less on par with the Galaxy S25 Ultra. While we've officially hit stagnation here (lithium-silicon batteries are already pushing 6,000mAh on phones like the OnePlus 13), we have high expectations for the battery life.
The difference between the two phones lies mostly in the browsing and gaming tests, where the Galaxy S25 Ultra has a notable lead.
When it comes to charging, both phones score 45W wired charging and 15W fast wireless charging. Yes, those are the same charging speeds as the past few generations; take that as you will.

Summary
The Galaxy S25 Ultra is the best one around, but the Galaxy S25 Plus is also a smart choice (Image by PhoneArena)
Samsung gives us "more of the same" with the Galaxy S25 Ultra and the Galaxy S25 Plus, while simultaneously improving some of the key areas that usually matter… and that's not bad, not bad at all!
After all, Samsung has been figuratively killing it with its flagship in the past few years and seemingly feels quite comfortable releasing consistently great phones, arguably the best Android ones you can get your hands on. Sure, one might argue that the company is no longer bold and its flagships are nowadays boring, yet we can't argue that Samsung has been continuously perfecting the formula.
As to which one should you get, that's entirely up to your size and feature needs: the Galaxy S25 Ultra is definitely the upper-tier and more feature-rich phone, with more head-turning aspects to it that will make it that much more premium than the Galaxy S25 Plus.
With unchanged prices, the Galaxy S25 Ultra starts at $300 more than the Galaxy S25 Plus, making the latter a better-value device. Still, there's no denying that the Galaxy S25 Ultra is among the hottest phones right now.
