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.
- Battery capacityBattery8,550 mAh vs 3,998 mAh — 2.1× more for the Xiaomi Redmi K90 Ultra
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.
- Peak brightnessDisplay9,500 nits vs 3,000 nits — 3.2× more for the Xiaomi Redmi K90 Ultra
Higher peak brightness is easier to read in direct sunlight.
- In-display fingerprintSecurity & softwareYes vs No — only the Xiaomi Redmi K90 Ultra has it
Unlock with a fingerprint sensor built into the screen.
- Ultrawide cameraCameras8 MP vs 48 MP — 6× more for the Apple iPhone 17 Pro
Captures a wider field of view for landscapes and groups.
More megapixels can capture more detail, but sensor size, optics and image processing decide most of what a photo actually looks like.
- Refresh rateDisplay165 Hz vs 120 Hz — 27% more for the Xiaomi Redmi K90 Ultra
A higher refresh rate produces smoother motion and scrolling.
The step from 60 to 120 Hz is obvious; differences above 120 Hz are far subtler in everyday use.
Which one should you buy?
There is no single answer — it depends on what you will actually use it for. Match your priority to the pick below.
- Best for display Xiaomi Redmi K90 Ultra takes the category 90 to 29 — driven by peak brightness (9,500 nits vs 3,000 nits).

Score breakdown
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.
