📷 Design & Build
At first glance, the S26 Ultra and S25 Ultra look very similar — Samsung hasn't reinvented the wheel here. But there are meaningful refinements.
The S26 Ultra is 0.3mm thinner at 7.9mm compared to the S25 Ultra's 8.2mm. While that sounds small on paper, it results in a noticeably more comfortable grip over long sessions. Samsung also shifted from individual protruding camera lenses to a unified vertical camera island on the back — a design Samsung fans have long requested. It looks cleaner and more premium.
The corners are also more rounded on the S26 Ultra, which addresses a common complaint about the S25 Ultra's sharper edges. Samsung replaced the titanium frame with a refined Armor Aluminum construction, which is lighter without sacrificing durability. Both phones have Corning Gorilla Armor on the front, but the S26 Ultra upgrades to Gorilla Armor 2 for better scratch resistance.
S26 Ultra
Slimmer (7.9mm), new camera island, more rounded corners, Gorilla Armor 2.
S25 Ultra
Iconic titanium frame design, premium feel. No visual complaints at all.
🔼 Display
Both phones share a 6.9-inch Dynamic AMOLED 2X panel with a 120Hz adaptive refresh rate. In terms of size and resolution, they are identical. However, the S26 Ultra makes two noteworthy improvements.
First, peak brightness jumps from 2,600 nits to 3,000 nits — making outdoor visibility in direct sunlight significantly better. Second — and this is the headline display feature — the S26 Ultra introduces the world's first built-in Privacy Display on a smartphone. Using pixel-level control (called Flex Magic Pixel technology), you can dim what others see from the side while keeping your screen fully visible straight-on. You can apply this to the full screen, specific apps, or just notifications and passwords. No privacy screen protector needed.
⚡ Performance & AI
The Galaxy S25 Ultra was already blazing fast thanks to the Snapdragon 8 Elite chip. The S26 Ultra steps it up with the Snapdragon 8 Elite Gen 5 — built on a newer 2nm architecture — which Samsung has further overclocked exclusively for the Galaxy.
In day-to-day tasks you won't feel a dramatic difference. But in demanding scenarios — sustained gaming, 8K video recording, real-time AI processing — the S26 Ultra pulls ahead. The improved NPU (neural processing unit) handles on-device AI tasks faster and more efficiently, which translates to quicker Galaxy AI responses and better photo processing speed.
RAM starts at 12GB on both phones, but the S26 Ultra's 1TB model bumps to 16GB RAM. This matters for running multiple heavy apps simultaneously and for future-proofing against AI workloads over the next 5–7 years.
📷 Camera System
This is where the S26 Ultra makes some of its most meaningful real-world improvements over the S25 Ultra.
Main Camera: A Bigger Aperture Changes Everything
Both phones use a 200MP main sensor, but the S26 Ultra widens the aperture from f/1.7 to f/1.4. This single change results in 47% more light entering the sensor — meaning dramatically better low-light photos, richer detail indoors, and improved night photography without requiring Night Mode.
Samsung also bumps the default capture mode from 12MP to 24MP — so every photo you take is sharper and more detailed without you needing to manually switch settings.
Ultrawide: The Biggest Camera Leap
The ultrawide is the most dramatic camera upgrade. The S25 Ultra had a 12MP ultrawide with f/2.2 and no autofocus — a weak point that many reviewers criticized. The S26 Ultra completely replaces this with a 50MP ultrawide at f/1.9 with autofocus. This is a generational improvement for group shots, architecture, landscapes, and close-up wide-angle photography.
Telephoto
The 3x telephoto (10MP) remains unchanged across both phones. The 5x periscope telephoto improves from f/3.4 to f/2.8 on the S26 Ultra — letting in more light at zoom distances. Both phones support up to 100x Space Zoom.
🔋 Battery & Charging
Both phones share an identical 5,000mAh battery — Samsung did not increase capacity on the Ultra model despite early rumors of a 5,500mAh cell. Battery life in real-world usage should be comparable between the two.
However, charging speed is a genuine upgrade. The S25 Ultra supports 45W wired charging. The S26 Ultra jumps to 60W — meaning you spend less time plugged in. Wireless charging also improves from 15W to 25W, which is a useful convenience upgrade if you use a wireless charger on your desk or nightstand.
Samsung has also confirmed faster reverse wireless charging for accessories like Galaxy Watch and Galaxy Buds.
60W Wired / 25W Wireless
0–50% significantly faster than the S25 Ultra's 45W. Wireless also up from 15W.
45W Wired / 15W Wireless
Still great battery life. The 5,000mAh cell is unchanged on both phones.
🤖 Software & Galaxy AI
The S26 Ultra ships with One UI 8.5 based on Android 16, Samsung's most AI-forward software release yet. The S25 Ultra launched on One UI 7 / Android 15, though it will receive the One UI 8.5 update as well.
Galaxy AI has been significantly expanded. Bixby now understands natural language for quick device settings and searches. Photo Assist and Creative Studio support 41 languages. "Now Nudge" gives you contextual suggestions based on your daily habits.
The S26 Ultra also adds support for Ray Tracing in mobile gaming, powered by the improved GPU inside the Snapdragon 8 Elite Gen 5. Games that support ray tracing will look visibly better on the S26 Ultra.
Both phones are promised 7 years of OS and security updates, meaning both are solid long-term investments.
💰 Price & Value
Available now (March 2026)
*Discounted since S26 launch
The S26 Ultra launches at the same starting price as the S25 Ultra. However, since the S26 has now launched, the S25 Ultra's price has dropped significantly — often to $999 or lower with carrier deals and trade-in offers. This makes the S25 Ultra an excellent value buy in 2026 for anyone who doesn't need the latest features.
In Europe, pricing starts at €1,469 for the S26 Ultra. Samsung is no longer offering the 128GB base model — 256GB is the new minimum storage across all S26 models.
🌟 Who Should Upgrade?
-
✓S23 Ultra or older users — Yes, absolutely upgrade. You'll feel the difference in every category: camera, performance, charging, display. The S26 Ultra is a massive leap over the S23 Ultra.
-
✓S24 Ultra users — Yes, worth it. Two full generations of improvement including the new camera system, 60W charging, and Privacy Display make this a compelling jump.
-
∼S25 Ultra users who care about cameras — Maybe. If you shoot a lot of photos, especially in low light or wide angle, the improved aperture and upgraded ultrawide are genuinely meaningful upgrades.
-
✗S25 Ultra users who just want performance — Probably not. Day-to-day the two phones feel nearly identical. The chip upgrade matters mostly for gaming and AI tasks.
-
✓Frequent travelers and commuters — Yes. The world's first built-in Privacy Display is a legitimately useful feature that no other phone offers. If you work in public spaces, this alone justifies the upgrade.
-
✗Budget-conscious S25 Ultra users — No need to upgrade. Buy a good case, keep it for 2–3 more years, and wait for the S27 Ultra instead.
S26 Ultra: A Meaningful, Not Mandatory, Upgrade
The Samsung Galaxy S26 Ultra is undeniably the better phone. Faster chip, better cameras, faster charging, a world-first Privacy Display, and improved build quality all add up to a genuinely improved flagship.
But "better" doesn't always mean "must buy." If you own the S25 Ultra, this is a good upgrade — not an essential one. If you're coming from an S23 Ultra or older, stop reading and place the order.
