Reviewers’ own scores: TechRadar 4.75/5 · Trusted Reviews 4.5/5 · Android Authority 9/10 · Tom’s Guide 4.5/5 · 9to5Google 4.5/5 · T3 5/5 · Beebom 9/10

The verdict

Across 14 reviews from 12 outlets, the S26 Ultra is a fast, bright-screened and versatile flagship, with better low-light photos and quicker wired charging than its predecessor. Battery life is solid but not class-leading, and reviewers split on the new Privacy Display and the AI features. 9to5Google reported in August that it was the world’s best-selling Android phone in the second quarter of 2026.

Best for: Android buyers who want top performance, strong zoom and a bright display, and who can handle a very large phone.
Skip it if: You want class-leading battery life, a compact phone, or built-in Qi2 magnets for wireless accessories.

What reviewers liked

  • Very fast and cool-running in the benchmarks and gaming tests that Android Authority, Beebom and others ran
  • Low-light camera and zoom improved, with strong zoom reported by Tom’s Guide and TechRadar
  • Bright, sharp display with a Privacy Display feature
  • Wired charging raised to 60W, with about 75-77% in 30 minutes in two measured tests
  • Thinner, lighter and more rounded than the S25 Ultra, with IP68 retained

What they didn’t

  • Battery life is about a day and not class-leading, and heavy users may struggle by evening
  • The 3x telephoto and AI zoom draw criticism, and some outlets say the camera hardware lags rivals
  • No built-in Qi2 magnets, and the phone is very large
  • Price coverage conflicts, and some outlets find it less compelling than cheaper rivals

In detail

Camera: 9.0/10

Reviewers agree low-light photography improved. Tom’s Guide measured images up to 47% brighter than the S25 Ultra, and Engadget saw sharper night shots with less noise and better exposure than the Pixel 10 Pro on backlit subjects. Zoom is the other strength: Tom’s Guide found it beats the iPhone, and TechRadar called 5x zoom sharper and usable to 50x. Weak spots vary by outlet. T3 and Trusted Reviews flag the 10MP 3x telephoto, Android Authority says AI zoom degrades quality, and Tom’s Guide found macro behind the iPhone 17 Pro Max. Confidence is medium, since some outlets gave little detail.

Battery life: 7.8/10

Most outlets say the battery comfortably lasts a day but is not class-leading. XDA Developers had 25-30% left at 9pm after typical use, and Beebom measured about 7.5 hours of screen-on time. Tom’s Guide measured 16 hours 10 minutes, nearly two hours behind the iPhone 17 Pro Max. Engadget’s video rundown lasted just over 30 hours, only 30 minutes longer than the S25 Ultra. FoneArena called it average for a flagship. 9to5Google found it drains faster than the iPhone 17 Pro Max under heavy use, and Trusted Reviews called the unchanged 5,000mAh battery merely fine. TechRadar was the most positive but gave no measurements.

Performance: 9.6/10

Every outlet that gave a verdict calls the Snapdragon 8 Elite Gen 5 fast with good thermals. Trusted Reviews and XDA Developers recorded Geekbench 6 multi-core results of 10,713 and 11,180, and Engadget found CPU speed 19% and GPU speed 24% above the S25 Ultra. Android Authority reported top graphics and ray-tracing results among tested phones and consistent output across 20 Wild Life Extreme runs. Beebom ran a 30-minute gaming session with no degradation, and XDA saw no lag in gaming or editing. 9to5Google gave no verdict on the Ultra’s performance, and some outlets gave no thermal detail.

Display: 8.8/10

Outlets agree the 6.9-inch display is bright, vibrant and sharp, and TechRadar lists a 1-120Hz refresh rate. Tom’s Guide measured 1,806 nits in HDR, slightly below the S25 Ultra, and noted narrower viewing angles. Privacy Display is the headline feature, but reviewers split on its cost. Engadget saw minimal effect on brightness and quality, while FoneArena found it reduces resolution and brightness. Trusted Reviews said maximum mode makes blacks look pale, and Beebom found it nearly unreadable at maximum. TechRadar found the default mode not very effective, though maximum protection works. T3 noted narrower viewing angles than the predecessor even with the feature off.

Software: 7.9/10

Reviewers agree Privacy Display is useful, with Tom’s Guide, SamMobile and 9to5Google noting per-app control. 9to5Google also credits the seven-year update promise. Beebom found One UI 8.5 smooth and polished, though it preferred Google Gemini to Bixby. AI is where outlets split. T3 found the Nudge feature failed to deliver in pre-release testing, XDA Developers called proactive features like Now Nudge unreliable or unavailable, and TechRadar felt there are too many AI options, some not working as promised. Engadget and XDA Developers praised Photo Assist for removing objects and reflections. Confidence is medium.

Charging: 8.2/10

All outlets agree wired charging rose to 60W and is faster than before. Trusted Reviews measured 75% in 30 minutes and a full charge in 53 minutes. Tom’s Guide measured 77% in 30 minutes, 6% better than the S25 Ultra, and noted wireless charging rose to 25W from 15W. 9to5Google said the speed makes 20-30 minute top-ups practical. XDA Developers and Android Authority both criticise the missing built-in Qi2 magnets, which means a case is needed for Qi2 accessories. T3 called it faster than its predecessor but did not measure it.

Design & build: 8.1/10

Outlets agree the S26 Ultra is thinner, lighter and more comfortable, with rounder corners and IP68 retained. Engadget cites 7.9mm and 214g, and Beebom found it comfortable to carry while travelling. Opinions differ on the trade-offs. TechRadar and Trusted Reviews flag the move from titanium to aluminium, though Engadget found the difference imperceptible. T3 and Tom’s Guide found noticeable desk wobble from the camera bump, and Tom’s Guide saw the back glass scratch within a week. FoneArena found the back slippery and S Pen insertion awkward. Android Authority calls it very large (163.3 x 78.1mm) and uncomfortable to hold for long, often needing two hands.

Value: 7.0/10

Evidence on value is thin and conflicting, so treat this as an early view. At launch, TechRadar and 9to5Google praised a $1,299 price unchanged from the previous model, and TechRadar judged it better value than the iPhone 17 Pro Max. 9to5Google also noted a $900 trade-in credit. Later coverage was cooler. Android Police reported $1,399 for 256GB, rising by up to $200 on the 1TB model, and CNET cited about $1,400 against the Pixel 11 Pro XL at $1,299. Android Authority found the steep pricing less compelling than the S26 Plus, Pixel 10 Pro XL or OnePlus 15. Engadget and SamMobile gave no verdict. The outlets did not specify the market for these dollar prices.
