Editorial report
Xiaomi Redmi K40 Pro 8 GB / 256 GB / China technical sheet
The Xiaomi Redmi K40 Pro suits anyone looking for a slim phone with especially extensive connectivity. At 7.8 mm thick, it is among the thinnest of its time; connectivity is among the best, with 5G, Wi-Fi 6E, and navigation systems including Galileo and NavIC. It also supports two Nano-SIM cards.
Its 6.67-inch Super AMOLED display pairs a 120 Hz refresh rate, better than most phones of its time, with peak brightness of 1300 nits, among the highest. Performance is better than most, and its AnTuTu result of 903,172 is among the best. This version has 6 GB of RAM and 128 GB of storage; the Redmi K40 Pro is sold in configurations from 6 GB / 128 GB to 8 GB / 256 GB.
The camera's 64 MP resolution and 1/1.7-inch sensor are better than most of its time. It records video up to 8K, but the f/1.9 aperture is worse than most and there is no optical image stabilization.

Its overall NeoScore is 6.3: a fit for buyers who prioritize connectivity, the display, and a slim profile, while accepting the camera and software limitations.
