Design and Size
A lighter build and a new look for the cameras

Last year Samsung massively reduced the thickness and weight of the Ultra model, so I didn’t expect the company to push even further on that front with this year’s model. Alas, Samsung has managed to reduce the thickness to just 7.9 mm, down from 8.2 mm on the S25 Ultra (8.6 mm on the S24 Ultra). The new model also weighs only 214 grams, 4 grams less than the S25 Ultra.
All of these reductions might not sound impressive at first, but keep in mind that these changes were one of the S25 Ultra’s strongest selling points back in 2025, and already massively impressive.
| Galaxy S26 Ultra | Galaxy S25 Ultra |
|---|---|
| Thickness 7.9 mm |
Thickness 8.2 mm |
| Dimensions Around 163.6 x 78.1 mm |
Dimensions 162.8 x 77.6 mm |
| Weight Around 214 grams |
Weight 218 grams |
If you are an avid fan of the S Pen, rest assured—it is still here. Also, the frame keeps its squared-off profile with rounded corners, and the phone remains IP68-rated for water and dust resistance.
Display Differences

It is great for marketing when you can boast about higher numbers, like 3,000 nits of peak brightness, for example. But Samsung is not doing that with the S26 Ultra. While the phone comes with the same peak brightness as its predecessor, it introduces a cool new feature—Privacy Display.

|---|---|
| Size 6.9″ |

| Brightness 2600 nits (peak) |

When enabled, Privacy Display narrows side viewing angles so the screen is harder to read from off-axis while keeping the image clear head-on. Samsung positions this as a built-in privacy layer rather than a software trick, and it can be customized to activate in specific moments like typing a PIN or when opening specific apps. Users can also choose between different strengths.
Performance and Software
Snapdragon for all regions, better heat management
The S26 Ultra comes with Qualcomm’s Snapdragon 8 Elite Gen 5 for Galaxy no matter where you buy it from. Samsung still refrains from splitting the chipsets with Exynos versions for the Ultra. That’s not the case with the S26 and S26 Plus, which are Snapdragon in the US, China, and Japan, and Exynos 2600 in Europe.
Performance-wise, Samsung says the S26 Ultra has a 19% faster CPU, a 24% stronger GPU, and a 39% improved NPU (responsible for AI features) compared to the Galaxy S25 Ultra. Clearly, the focus was on improving the performance of AI-related functions.
There is also a redesigned vapor chamber and other small improvements to help the S26 Ultra maintain peak performance levels for longer than the S25 Ultra.

RAM, Storage 12/256 GB 12/512 GB 12/1 TB 16/1 TB LPDDR5X RAM |
As for the storage and memory, Samsung keeps the same simple rule: 256 GB and 512 GB models come with 12 GB RAM, while the 1 TB model comes with 16 GB RAM. For now, I assume the storage type is UFS 4.0, although this is still not confirmed at this stage.
There are no AI features that won’t be available on the S25 Ultra. Both phones come with Samsung’s Now Brief and Now Bar experiences (plus the new Now Nudge behaviors) that surface relevant actions and information throughout the day. Samsung explicitly mentioned Gemini and Perplexity integration alongside its own tools too.

The S26 Ultra’s cameras will sound very familiar: a 200 MP main camera, a 50 MP ultrawide, a 10 MP 3x telephoto and a 50 MP 5x telephoto.

3x Telephoto 10 MP, f/2.4 3x zoom (67mm) 1/3.52″ sensor size |
Samsung is also leaning harder into creator-focused video tools this year. The Galaxy S26 Ultra supports 8K recording at 30 fps and adds 4K recording at up to 120 fps in Pro Video mode. It also introduces support for APV, which stands for Advanced Professional Video. APV is a new high-quality video format designed to preserve more detail, dynamic range, and color information during recording, giving users more control during their workflow.
This makes the S26 Ultra better suited for serious content creation because it allows users to edit footage with more flexibility in post-production.

Battery Life and Charging
Same battery capacity, but with faster wired and wireless charging
Same 5,000 mAh, but 60W wired and 25W wireless make the S26 Ultra much quicker to top up. | Image by PhoneArena
For yet another year, Samsung has decided to keep the same 5,000 mAh battery inside the Ultra, so if we see any improvements, they will most likely come from the new chipset.
However, the difference between the S26 Ultra and the S25 Ultra is that the new model comes with Samsung’s Super Fast Charging 3.0, which basically means you get 60W wired charging. Samsung claims this is enough to charge the S26 Ultra to 75% in roughly 30 minutes under “optimal conditions.” We’ll let you know our results soon.

Summary
Great upgrades, but not FOMO worthy. The S26 Ultra is a strong successor, not a must. | Image by PhoneArena
The Galaxy S26 Ultra brings a few notable upgrades like faster charging, a faster processor that’s much better at AI, and a new and unique privacy feature. We also have improved optics for the main and 5x telephoto cameras. All great stuff!
Now, whether the new model is worth upgrading to if you own the S25 Ultra—I don’t think so. We no longer live in an age where each new generation can justify such an early upgrade. It doesn’t look like there is any danger of FOMO with the S26 Ultra.
