NeoTeo's verdict
Which of the two is the better buy
The Xiaomi Poco C85x is the clear pick for higher performance, better cameras, and 5G; the Poco C81 only makes sense if it costs less. Its 479,500 AnTuTu score, UFS 2.2 storage, and 128 GB pull ahead of the C81’s 308,681, eMMC 5.1, and 64 GB.
Both phones use a 6.9-inch IPS LCD with 720 × 1600 resolution, 254 ppi, and 120Hz refresh. The C85x adds stereo speakers, while the Poco C81 uses glass and plastic rather than the C85x’s plastic build; these are differences in approach, not reasons to overturn the verdict.
The C85x’s main camera reaches 32 MP versus 13 MP, while Bluetooth 5.4 and 5G beat the C81’s Bluetooth 5.2 and 4G. Battery hardware is level: both have 6,300 mAh, 15W charging, and reverse charging; the C81 also includes a charger.
Xiaomi Poco C85x
The Xiaomi Poco C85x is the better buy for performance and 5G, with 479,500 in AnTuTu and faster UFS 2.2 storage.
Xiaomi Poco C81
The Xiaomi Poco C81 is only the better buy if it costs less: its glass-and-plastic build cannot offset weaker performance, cameras, and 5G.
