Samsung Galaxy S26 Ultra vs S25 Ultra – Full Specs Comparison 2026

Samsung's Ultra lineup has always set the benchmark for Android excellence — and 2026 is no different. With the Galaxy S26 Ultra now official, the big question is whether it's a meaningful upgrade over the already-impressive Galaxy S25 Ultra. Here's a complete specs breakdown to help you decide.

Design & Display

Both devices feature curved-edge Dynamic AMOLED 2X panels with 120Hz adaptive refresh rates, but the S26 Ultra steps up with a brighter peak luminance — reaching up to 2,600 nits compared to the S25 Ultra's 2,200 nits. The S26 Ultra also refines its titanium frame with a slightly slimmer profile, making it marginally more comfortable for one-handed use despite its large footprint.

Chipset & Performance

The Galaxy S25 Ultra runs on the Qualcomm Snapdragon 8 Elite — one of the fastest mobile chips of its generation. The S26 Ultra upgrades to the next-generation Snapdragon 8 Elite 2 (Gen 2), delivering noticeable gains in AI-assisted tasks, on-device processing, and thermal efficiency. For everyday use, both feel lightning fast — but the S26 Ultra holds a clear edge in sustained workloads and gaming sessions.

Camera System

Samsung's camera evolution is evident here. The S25 Ultra's 200MP main sensor was already class-leading, but the S26 Ultra introduces improved per-pixel binning and a new 50MP periscope telephoto with enhanced optical zoom range. Video creators will appreciate the S26 Ultra's upgraded stabilization algorithm and ProVideo 8K improvements.

Battery & Charging

Both models carry a 5,000mAh battery with 45W wired charging. The S26 Ultra improves efficiency through its newer chipset, translating to slightly longer screen-on time despite identical battery capacity. Wireless charging remains at 15W on both.

Is the S26 Ultra Worth the Upgrade?

If you're coming from the S24 Ultra or earlier, the S26 Ultra is a compelling leap. S25 Ultra owners may want to wait another generation.
