About Xiaomi Redmi K40 5G
The Xiaomi Redmi K40 5G presents a sleek silhouette, measuring 76.4 mm wide, 163.7 mm tall and just 7.8 mm thick, while tipping the scales at a modest 196 grams. Its front is dominated by a 6.67‑inch AM‑OLED panel that delivers vivid colours and deep blacks at a Full HD+ resolution of 1080 by 2400 pixels, offering a comfortable viewing experience for media and gaming alike.
Under the hood, the device runs Google Android 11 out of the box and is equipped with a generous 12 GiB of RAM, ensuring smooth multitasking and responsive performance. Power comes from a 4520 mAh battery designed to keep the phone going through a day of typical use, and connectivity is handled via a single SIM slot, keeping the design straightforward while still supporting 5G networks.
Unlike the base model’s single SIM slot and 12 GiB of RAM, this Premium Edition provides dual‑SIM capability and 8 GiB of RAM while increasing internal storage to 256 GB. Compared with the other K40 5G variants, it matches the Top Edition’s dual‑SIM TD‑LTE CN configuration and 256 GB storage but offers less RAM; it shares the Premium Edition’s dual‑SIM TD‑LTE CN setup and 8 GiB RAM but doubles the storage of the 128 GB Premium model; and it surpasses the Standard Edition in both RAM and storage while retaining the same dual‑SIM TD‑LTE CN arrangement.
