Last year, Samsung embraced artificial intelligence with its range of… Galaxy AI features. Although the new S25 Ultra is a little faster, a little curvier, and has a slightly larger screen than before, it’s clear that the company’s primary focus has been on upgrading the software and machine learning capabilities of its high-spec flagship. But is this enough?

Similar to The previous onethe Galaxy S25 Ultra Features a titanium frame. However, in 2025, Samsung wanted to break with tradition by making the phone a little slimmer. So, instead of a completely angular body, Samsung has rounded its corners. This gives the Ultra a greater degree of family resemblance to its less expensive siblings (both the S25 and S25+). However, the Ultra still has sharper flat edges than last year’s phone, so it’s more of a remix than a complete revamp.

For the front and back glass, Samsung has moved to Corning’s new Gorilla Armor 2, which features a “next-generation” anti-reflective coating that helps eliminate glare more than before. But perhaps the best new hardware upgrade is a larger 6.9-inch QHD+ AMOLED display (compared to 6.8 inches) with 15 percent smaller bezels, allowing for more screen real estate without increasing the phone’s overall dimensions (6.41 x 3.05 x 0.32 inches).

On the other hand, the S Pen included with the S25 Ultra is actually getting a slight downgrade as Samsung is removing Bluetooth Low Energy support from the stylus. This may seem a bit confusing, but Samsung claims that only a small percentage of owners were using it Air procedures (Which was the only S Pen feature that required BT LE) By getting rid of it, the stylus is more durable than before because you don’t have to worry about outfitting it with tiny radios. The company also says that the only gesture that saw significant use was that of turning on the phone’s camera remotely, which can be achieved in several other ways (e.g. raising your palm or using the Galaxy Watch or Galaxy Ring).

Another design quirk is that although the S25 family (including the Ultra) supports up to 15W wireless charging, they’re not technically fully Qi2 compatible. Instead, Samsung says the phone is “Qi2-ready” which means it will work with compatible chargers, but since there aren’t any alignment magnets inside the phone, users will need to rely on aftermarket cases to provide a suitable mounting point for the magnets. Supplements.

The final noteworthy hardware addition is a new 50MP sensor for the ultra-wide camera, which joins the three returning from Phone last year: 200-megapixel main cameras, 10-megapixel telephoto cameras, and 50-megapixel telephoto cameras (with the latter two offering 3x and 5x optical zoom, respectively). Samsung says there should be some general improvements in image and image processing thanks to the new S25 Ultra chip, such as improved noise reduction and a better spatial and temporal filter that can more accurately distinguish between moving and stationary objects. But we’ll wait until we can review the phone to say what these features can really do.

Inside, the S25 Ultra is powered by Qualcomm’s Snapdragon 8 Elite for the Galaxy chip along with 12GB of RAM and up to 1TB of storage. For buyers outside of North America, Samsung says it’s using the same SoC worldwide instead of selecting its own Exynos chipsets in certain regions as it has done in the past. The company claims that overall CPU performance increased by 37 percent year-on-year. Meanwhile, GPU speeds rose by 30 percent while the S25 Ultra’s NPU got the biggest increase of around 40 percent. To help provide improved sustained performance for things like gaming, Samsung claims the S25 Ultra’s vapor chamber is 40 percent larger than before.

In real life, the phone felt as responsive as expected, though it was hard to tell whether that was all thanks to the phone’s new chip or whether it was partly due to the snappier animations in One UI 7, which will come pre-installed on the device. Galaxy S25 family. As before, Samsung Continue to provide seven years Regular operating system updates and security patches.

Of course, as with many other recent devices, the S25’s main focus is on expanded AI functionality and after introducing the first set of features on the S24 line last year, it seems Samsung’s goal was to make everything a little more powerful and a little easier. To use. For example, existing tools like Smart Select have been renamed to AI Select and turned into what the company calls AI agents. Overall, this means that a single feature will support a broader range of capabilities and improved contextual awareness.

Now when you tap on the AI ​​Select icon after pulling down Samsung’s sidebar, the phone will analyze everything you’re looking at and offer a variety of suggestions like taking a screenshot, performing a visual search, summarizing an article, or even taking a video and turning it into a GIF. It’s a mode similar to Samsung’s Sketch to Image tool renamed to Draw Assist, which not only provides more realistic results, but also allows you to add AI-generated artwork to photos by roughly drawing something with the S Pen or simply Use text. Demands. Even Google’s Search Circle feature got a slight upgrade as it stands now Supports song identification Either by listening to music or by singing a tune.
