Key real-world differences

The spec sheet pulls in both directions. These are the gaps big enough to shape the decision — with the actual figures, and what each one means in real-world use.

  1. 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.

  2. 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.

  3. Front cameraCameras
    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.

  4. Wired chargingBattery
    60 W vs 100 W — 40% more for the Xiaomi 17 Max

    Higher wattage charges the battery faster over a cable.

  5. Stylus supportDesign
    Yes vs No — only the Samsung Galaxy S26 Ultra has it

    The device works with an active stylus pen.

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.
