This comparison puts the Samsung Galaxy S26 Ultra and Xiaomi 17 Max side by side — two smartphones measured against the same 99-spec sheet, with every meaningful gap scored and explained. On our weighted VS Score the Samsung Galaxy S26 Ultra finishes ahead, 83 to 77 — a solid lead.
The single biggest measurable gap is battery capacity: 5,000 mAh vs 8,000 mAh. A transparency note before you dive in: the spec sheets are Samsung Galaxy S26 Ultra 88% and Xiaomi 17 Max 87% complete. Anything unverified shows as Unknown and is left out of the scores — we never estimate a missing value.

Battery capacityBattery
5,000 mAh vs 8,000 mAh — 38% more for the Xiaomi 17 Max
A larger battery generally lasts longer between charges.
Capacity is a proxy, not a promise — display, chip efficiency and software decide how long a charge really lasts.
Telephoto cameraCameras
10 MP vs 50 MP — 5× more for the Xiaomi 17 Max
Enables closer, higher-quality zoom shots.
More megapixels can capture more detail, but sensor size, optics and image processing decide most of what a photo actually looks like.

12 MP vs 32 MP — 2.7× more for the Xiaomi 17 Max
A higher resolution front camera improves selfies and video calls.
More megapixels can capture more detail, but sensor size, optics and image processing decide most of what a photo actually looks like.

How the VS Score works — and what it can’t tell you
Every measurable spec is scored relative to this matchup: the best value here earns 100%, the worst 0%, and everything between scales linearly. Each spec then counts according to an editorial weight that reflects real-world impact — a battery-capacity gap moves the score far more than a colour-options list. The category scores above are the weighted results inside each group, and the overall VS Score rolls all of them together; the evidence line under each category names the specs that actually decided it.
Unknown values are never estimated. A spec a product doesn’t report simply drops out of that product’s scoring — it isn’t penalised with a guess — and a spec only one side reports can never produce a “win”. The trade-off is honest but real: a thinner spec sheet means a score built on fewer data points, which is why the completeness figures are disclosed under About this data.
Most importantly: a spec-sheet lead is not the same as a better product. Megapixels, gigahertz and benchmark points describe capacity, not experience — image processing, software optimisation, thermals, haptics and ergonomics decide how a device actually feels, and no table captures reliability or long-term support quality. Treat the scores as a structured summary of what can be measured, read the caveats under each key difference, and use the weight tuner to re-rank the comparison by what matters to you.

About this data
Specifications are compiled from each manufacturer’s official spec sheet, cross-checked against trusted specification databases, and normalised into one schema so identical things are compared identically.
Specifications last verified July 14, 2026.
Data completeness: Samsung Galaxy S26 Ultra 88% and Xiaomi 17 Max 87% of the 99 specs in this category. Anything we could not verify is shown as Unknown — never estimated — and is excluded from all scores.
Prices and availability come from live retailer feeds via our shopping partners and refresh throughout the day; a missing price means no partner currently lists the product, not that it is discontinued.
