Xiaomi Poco C81 review
This review measures the Xiaomi Poco C81 against the full 99-spec sheet we track for smartphones, comparing it like for like with the 106 other models in our database. It earns a VS Score of 23 out of 100 — the weighted result of every verified specification measured against the class average.
On the spec sheet it is strongest in design and weakest in cameras. Its clearest single advantage over the class average: 0.15 " more screen size — 6.9 " vs 6.75 " (avg). None of our retail partners currently lists the Xiaomi Poco C81, so availability may be limited; a missing price never affects the VS Score. A transparency note: this spec sheet is 82% complete. Anything unverified shows as Unknown and is left out of the score — we never estimate a missing value.

Editor’s note
The Poco C81 is an entry-level phone at around €100, and it spends its budget on the two things budget buyers notice: screen smoothness and battery life. The 6.9-inch LCD runs at 120Hz, which makes scrolling feel far better than the 60Hz panels still common at this price, and the 6300mAh battery is genuinely large — two days of light use is realistic.
It also keeps the practical features that get stripped from more expensive phones. There is a dedicated microSD slot alongside the 64GB of storage, a 3.5mm headphone jack, FM radio and a side-mounted fingerprint reader. Xiaomi promises up to four major Android upgrades from Android 16 with HyperOS 3, which is a longer commitment than budget phones usually get.
The compromises are substantial and you should read them carefully. This is a 4G-only phone — there is no 5G at all, which in 2026 is a real limitation on longevity. The screen is 720×1600, so about 254 pixels per inch across 6.9 inches: text and images look soft. There are 4GB of RAM and eMMC 5.1 storage, so app switching is slow and heavy apps will reload. The Unisoc T7250 is a modest 12nm chip. Charging is 15W, so refilling that big battery takes a long time. There is a single 13MP rear camera, no NFC for contactless payments, a mono speaker, and no gyroscope — which breaks some games and AR features.
Buy it as a first phone, a child's phone or a backup where battery life and price are everything. Skip it if you want 5G, contactless payments, a sharp screen or usable cameras — even a small budget increase changes all four.

How the VS Score works — and what it can’t tell you
Every measurable spec is scored against the average of all the smartphones we track: matching the class average scores 50, clearly beating it climbs towards 100, and each spec 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 quality bars on the spec cards above show where this model sits inside the full range for its class, and the overall VS Score rolls every weighted result into one number.
Unknown values are never estimated. A spec this product doesn’t report simply drops out of its scoring — it isn’t penalised with a guess — but a thinner spec sheet does mean a score built on fewer data points, which is why completeness is 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 VS Score as a structured summary of what can be measured, not a substitute for your own priorities.
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 27, 2026.
- Data completeness: 81 of the 99 specs in this category are verified (82%). Anything we could not verify is shown as Unknown — never estimated — and is excluded from the score.
- 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.
- Want the full picture? Our editorial guidelines explain how we research products, weight the scores and stay independent.
