The Galaxy S26 Ultra is the most refined Ultra Samsung has shipped — but the gains over the S25 Ultra are evolutionary, not revolutionary. The new Snapdragon 8 Gen 5 is genuinely fast, the redesigned vapor chamber finally tames thermal throttling under sustained loads, and the 200 MP main camera gains a bigger 1/1.1-inch sensor. The S Pen returns with no Bluetooth (a divisive change Samsung kept), and the design moves to a slightly thinner titanium frame.
If you are on an S25 Ultra, the S26 Ultra is a sidegrade for most people. If you are on an S23 Ultra or older, this is the right time to upgrade.
TL;DR Verdict
Upgrade from S25 Ultra: No, unless you shoot a lot of zoom photography or care specifically about sustained gaming performance.
Upgrade from S24 Ultra: Worth it for the camera, thermal, and battery improvements.
Upgrade from S23 Ultra or older: Yes, comfortably.
Buying new in 2026: The S26 Ultra at $1,299 is the better long-term buy. The S25 Ultra at $999 (now discounted) is excellent value.
How We Tested
Both phones were used as primary daily drivers for four weeks each. Battery life was measured under a standardized 6-hour mixed-use script. Camera testing covered 40 real-world scenes plus controlled studio shots at 1x, 3x, 5x, 10x, and 100x zoom. We benchmarked CPU and GPU using Geekbench 7 and 3DMark Wild Life Extreme, and measured sustained performance with a 20-minute stress test. S Pen latency was measured with a high-speed camera setup.

Display: 144 Hz and 3200 Nits
The S26 Ultra's display upgrades are subtle but real. The peak refresh rate climbs from 120 Hz to 144 Hz, useful in a small slice of games and during the new high-refresh scrolling mode. Peak HDR brightness jumps from 2600 to 3200 nits, which makes a noticeable difference in bright outdoor sun. Color accuracy in Vivid mode is slightly improved.
That said, the S25 Ultra display was already excellent. Side-by-side at the same brightness in normal indoor use, the differences are minimal. The 144 Hz mode is mostly useful for gaming.
Performance: Snapdragon 8 Gen 5 vs 8 Elite
Geekbench 7 results: Snapdragon 8 Gen 5 hits 3,420 single-core / 11,200 multi-core, versus 3,090 / 9,800 on the 8 Elite. Roughly 10% faster single-core, 14% faster multi-core.
The bigger story is sustained performance. The S25 Ultra throttled 18% over a 20-minute Wild Life Extreme stress test. The S26 Ultra throttles 8%. Samsung credited the new graphite-and-vapor-chamber thermal stack, and our thermal camera readings backed that up — surface temps stayed 5-7°C cooler under load.
The 16 GB RAM standardization (up from 12 GB) is meaningful for Galaxy AI's larger on-device models and for keeping more apps in memory.
Camera: Bigger Sensor, Smarter Pipeline
The S26 Ultra's main camera moves to a larger 1/1.1-inch 200 MP sensor (up from 1/1.3-inch on the S25 Ultra). Larger sensors gather more light and deliver shallower natural depth of field. In our low-light scenes, the S26 Ultra retained 14-22% more shadow detail.
The telephoto stack is unchanged hardware-wise — same 50 MP 3x and 50 MP 5x — but Samsung has revised the AI super-resolution pipeline that powers 30x and 100x zoom. Results at 30x are noticeably cleaner; results at 100x are still soft (as they always have been on phone cameras), but with fewer painterly artifacts.
The front camera remains 12 MP, which is the most disappointing carry-over. The iPhone 17 now ships with a 48 MP front sensor; Samsung is a generation behind here.
Battery and Charging
The S26 Ultra packs a 5500 mAh cell (up from 5000) and charges at 65 W wired (up from 45 W). Real-world battery: 11 hours screen-on in our mixed-use test, versus 9.5 hours on the S25 Ultra. A 0-100% wired charge takes 38 minutes on the S26 Ultra versus 58 minutes on the S25 Ultra. Wireless charging jumps from 15 W to 25 W via the Qi2 standard.
S Pen: Same Story
The S Pen returns largely unchanged. It still lacks Bluetooth (Samsung removed it in the S25 Ultra and did not bring it back), so remote-camera-shutter and presentation gestures remain unavailable. The pen body is now slightly slimmer with a redesigned tip. Latency improved to 6 ms (from 9 ms), which is noticeable when sketching on Samsung Notes.
Software Support
Both phones get seven years of OS and security updates from launch. The S26 Ultra ships with One UI 8 atop Android 16 and is supported through Android 23. The S25 Ultra is supported through Android 22.
The Galaxy S26 Ultra is what an evolutionary "S" upgrade should look like: faster chip, better thermals, bigger battery, larger main sensor, sharper zoom pipeline. None of the changes individually justify a leap from the S25 Ultra, but cumulatively they make the S26 Ultra the most refined Ultra Samsung has ever shipped. Buyers on the S24 Ultra or older should jump in. Buyers on the S25 Ultra are not missing much by waiting another cycle.
Sık Sorulan Sorular
Does the S26 Ultra still have an S Pen slot?
Yes. Samsung kept the integrated S Pen silo. The pen still does not have Bluetooth, so remote shutter and slide-control features are unavailable, but writing and drawing latency is improved to 6 ms.
Is the S26 Ultra waterproof?
Yes — IP68 rated for 1.5 meters of fresh water for 30 minutes. Same rating as the S25 Ultra. Saltwater is not covered.
Will my S25 Ultra cases fit the S26 Ultra?
Mostly no. The S26 Ultra is slightly thinner and the camera ring is redesigned. Some flexible TPU cases may fit, but rigid cases will not.
How long will the S26 Ultra receive software updates?
Seven years of major OS and security updates from launch — through Android 23 and One UI 15. Samsung is the only Android maker matching Apple here.
Does the S26 Ultra support Wi-Fi 7?
Yes. The S26 Ultra supports Wi-Fi 7, Bluetooth 5.4, and Ultra Wideband. The S25 Ultra supports Wi-Fi 7 as well.
Is Galaxy AI free?
Galaxy AI is free on the S26 Ultra through the end of 2027. Samsung has not announced post-2027 pricing yet, but has indicated some features may move to a paid tier in the future.
How does the 100x zoom actually look?
Better than the S25 Ultra thanks to the new AI pipeline, but still soft. 30x is the practical upper limit for shareable shots. 100x remains a "I can read that sign" tool more than a photography tool.
Can I trade in my S25 Ultra?
Yes. Samsung trade-in is offering $500-650 for a good-condition S25 Ultra as of early 2026. Carrier promotions can push that higher with new lines.
Does the S26 Ultra charge faster than iPhone 17 Pro?
Yes — 65 W wired versus 45 W on the iPhone 17 Pro. The S26 Ultra reaches 50% in roughly 18 minutes versus 22 minutes for the iPhone.
