Design and Size
Samsung is going thin

On the other hand, the OnePlus 13 sticks to its core values: clean, modern design. Some might not be big fans of the large circular camera module at the back, but a nice saving grace is the phone’s unique Arctic Dawn finish that does not attract fingerprints or scratches and is less slippery.

Dimensions are 162.8 x 77.6 x 8.2 mm, which is slightly more compact than the competition. And, of course, Samsung’s signature S-Pen is still integrated into the phone, adding a layer of productivity for note-takers and creatives. But maybe it is in particular the S-Pen that makes the S25 Ultra around 9 grams heavier than the OnePlus 13.
As a side-note, we noticed that Samsung has removed Bluetooth connectivity from this new version, which could be seen as an indication that the company is thinking of ditching this feature in future products.
The OnePlus 13 measures 162.9 x 76.5 x 8.5mm, which makes it just a touch taller and thicker than the S25 Ultra. What stands out, though, is its extreme durability. With IP68 and IP69 ratings, this phone is built to handle water and dust like a champ.
In other words, you should be able to throw the OnePlus 13 in a washing machine without any worries of it breaking.
Keep in mind, these ratings are based on tests in controlled environments. Real-world factors like saltwater, soap, or hard drops can still cause damage, so always check the manufacturer’s guidelines.
Display Differences

Samsung continues to set the standard in display technology. The Galaxy S25 Ultra boasts a 6.9-inch LTPO OLED screen with a dynamic refresh rate of 1–120Hz. It’s protected by Gorilla Glass Armor 2, which great anti-reflective coating for better visibility in bright conditions. Samsung’s displays are known for their vibrant colors, deep contrast, and industry-leading HDR10+ visuals, and the S25 Ultra is no exception.
The OnePlus 13, on the other hand, features a slightly larger 6.8-inch QHD OLED display. While it matches Samsung in refresh rate and resolution, its Crystal Shield ceramic glass lacks the anti-reflective properties of Gorilla Glass Armor. However, OnePlus introduces Eye Care 4.0 certification, which reduces blue light for more comfortable viewing during extended use. What’s more, there’s also the Aqua Touch 2.0, which makes the OnePlus 13 even more responsive than its predecessor when operated with wet fingers or gloves.

Camera
New image sensors on both sides

Virtual Aperture is another standout feature, giving users greater creative control over depth of field, while Galaxy Log introduces professional-grade video recording capabilities with richer color grading potential.
On the other end of the ring we have the OnePlus 13, which comes equipped with a Hasselblad-tuned triple-camera system. You get a 50MP main sensor, a 50MP ultra-wide camera with a 120° field of view, and a 50MP telephoto lens offering 3X optical zoom.
While the OnePlus 13 camera upgrades bring sharper images and better low-light performance compared to previous years, we found the photos to be overly processed. Colors tend to be too vivid, and HDR effects can feel exaggerated, which might not appeal to everyone. The phone also features 120x digital zoom, but the results rely heavily on AI upscaling and don’t quite match the quality of true periscope-style zoom lenses like on the Galaxy Ultra. The 32MP front camera is serviceable but doesn’t stand out compared to competitors.
In our testing, the OnePlus 13 earned a score of 144.9—an improvement over the OnePlus 12 but still trailing behind heavyweights like the Galaxy S24 Ultra. So, we do expect the S25 Ultra to be noticeably better when it comes to camera quality, at least in some areas.
Battery Life and Charging
OnePlus 13 has much faster charging

Something OnePlus has going for it though, is a new Silicon NanoStack tech, said to be much better at preserving the long-term battery health.
Another area where the OnePlus 13 beats the S25 Ultra is charging, with 80W wired charging and 50W wireless charging vs the 45W wired and 15W wireless on the S25 Ultra.

Summary

Comparing the OnePlus 13 and the Galaxy S25 Ultra is an interesting exercise, especially since they each bring something unique to the table. The OnePlus 13 seems like a fantastic option for those who care about getting good value without compromising on key features. The world-class charging capabilities, awesome display technology, and the new cameras are nothing to scoff at, especially when you factor in the competitive price and solid build quality.
The Galaxy S25 Ultra on the other hand comes with better support and the S-Pen. More importantly, its camera system is still better in many cases. There’s that Gorilla Glass Armor 2 that we love here at the office.
But if we are strictly speaking bang for your buck here, the OnePlus 13 is the more clear choice, at least for most users. Unless you are in need of the extra benefits that come with the S25 Ultra, than it’s hard to justify the price difference between these two phones.
