Editorial report
Xiaomi Redmi K20 technical sheet
The Xiaomi Redmi K20 suits buyers looking for a mid-range phone with an AMOLED display and optical zoom, but at 191 g it weighs more than most phones launched around the same time. That is a trade-off for anyone who puts a light phone first; its body is 8.8 mm thick.
Its 6.39-inch Super AMOLED display reaches 600 nits peak brightness, above average for phones of its time. Pixel density is 403 ppi, higher than on most phones from that period. Gorilla Glass 5, HDR, and Always-On Display round out the screen features. The Snapdragon 730 is paired with 8 GB RAM and 256 GB storage. Its AnTuTu result of 261,545 is above average, and the hardware stands better than that of most phones launched around the same time.
The main camera uses a 48 MP, 1/2-inch sensor, larger than average, while 2x optical zoom is among the best on phones of its time. There is also an ultrawide camera and slow-motion video at up to 960 fps. Connectivity is better than on most phones launched around the same time, with NFC, a 3.5 mm audio jack, and dual Nano-SIM. The 4,000 mAh battery and 18 W charging are average figures.
With a NeoScore of 5.1, the Redmi K20 is a balanced choice for buyers who value its display and zoom more than a lighter handset.
