The Samsung Galaxy S26 Ultra is the camera and productivity flagship at the top of Samsung's current range, with a 6.9-inch screen, four rear cameras and stylus support. Unlike the Galaxy S26 and S26+, it runs the Snapdragon 8 Elite Gen 5 in every market, so UK buyers get the same chip as US buyers rather than the Exynos alternative fitted to its siblings.
The 6.9-inch Dynamic LTPO AMOLED 2X panel runs at 120Hz with a 1440 x 3120 resolution and is the only phone in the range with Gorilla Armor 2, an anti-reflective coating and a Privacy Display mode that narrows viewing angles. GSMArena measured 1,480 nits of maximum brightness in its lab test, with the quoted 2,600-nit peak reserved for HDR content.
The anti-reflective glass is the practical differentiator over the S26+, because the measured brightness between the two is close enough that raw output alone does not justify the step up.
The quad camera is the reason this phone exists: a 200MP f/1.4 main sensor with OIS, a 50MP periscope with 5x optical zoom, a 10MP 3x telephoto and a 50MP ultrawide. Video reaches 8K at 30fps and 4K at 120fps, a frame-rate option the S26 and S26+ do not offer.
The 10MP 3x mid-zoom is the weak link in an otherwise high-spec array, carried over unchanged at a lower resolution than the lenses either side of it.
The 5,000mAh battery charges at 60W wired, quoted at 75% in 30 minutes, the fastest in the current Galaxy S range, with 25W Qi2.2 wireless alongside. GSMArena's lab returned an active use score of 16:23 hours.
That endurance figure is effectively level with the lighter Galaxy S26+ at 16:25 hours, so the bigger cell is absorbed by the bigger screen rather than delivering longer runtimes.
At 163.6 x 78.1 x 7.9mm and 214g, the Ultra pairs its Gorilla Armor 2 front with a Victus 2 back, an Armor aluminium 2 frame and IP68 sealing, and stylus input is supported for notes and markup.
This is a heavy, wide phone: 24g more than the S26+ and 47g more than the S26, and the 78.1mm width will rule out comfortable one-handed use for most people.
The Snapdragon 8 Elite Gen 5 comes with 12GB of RAM on the 256GB and 512GB models and 16GB on the 1TB version, shipping on Android 16 with One UI 8.5 and a commitment to up to seven major Android upgrades that has only just started. Samsung DeX and UWB support round out the productivity case.
Only the 1TB model gets 16GB of RAM, so buyers wanting maximum memory are pushed to the most expensive configuration.
Buy the Galaxy S26 Ultra if zoom photography or stylus work is central to how you use a phone; it is the only device in the range that offers either, and it suits buyers on older Ultra models whose update windows are winding down. If neither matters to you, the Galaxy S26+ delivers near-identical endurance and the same screen size class with less weight. Buyers comparing contract length or upfront cost will find current network pricing in the table above.
