About Xiaomi Redmi K20
The Xiaomi Redmi K20 presents a sleek profile with dimensions of 74.3 mm wide, 156.7 mm tall and 8.8 mm thick, weighing in at 191 grams. Its front is dominated by a 6.39‑inch AM‑OLED panel that delivers a Full HD+ resolution of 1080 by 2340 pixels, offering vivid colours and deep contrasts typical of the technology. The smooth curves and minimal bezels give the device a modern feel while keeping the overall footprint comfortable for one‑handed use.
Under the hood, the phone runs Google Android 9.0 Pie out of the box, paired with a generous 8 GiB of RAM to handle multitasking and demanding apps with ease. Power comes from a 4 000 mAh battery, aiming to provide a full day of moderate usage before needing a recharge. Connectivity is handled through a single SIM slot, keeping the design straightforward for users who prefer a unified mobile experience.
This variant reduces the RAM to 6 GiB compared with the base model’s 8 GiB, while offering 128 GB of storage and targeting the Indian market.
Unlike the Indian‑market sibling that provides only 64 GB, this model doubles the storage to 128 GB with the same 6 GiB RAM. In contrast, the China‑market editions are dual‑SIM and available in 64 GB, 128 GB or 256 GB configurations, with one of them stepping up to 8 GiB of RAM.
