About Xiaomi Mi 12S Ultra 5G
The Xiaomi Mi 12S Ultra 5G presents a sleek profile with dimensions of roughly 75 mm wide, 163 mm tall and just over 9 mm thick, fitting comfortably in the hand despite its solid 225‑gram build. At the front lies a 6.73‑inch AM‑OLED panel that delivers vivid colours and sharp detail thanks to its 1440 × 3200 pixel resolution, offering an immersive viewing experience for media and gaming alike.
Inside, the device runs Google Android 12 (S) and is backed by 12 GiB of RAM, ensuring smooth multitasking and responsive performance. Power comes from a 4860 mAh battery that supports 50‑watt wired charging, allowing the phone to replenish quickly when needed. Connectivity is handled through a single SIM slot, keeping the design streamlined while still providing reliable 5G capability.
Unlike the base model, this version is branded as the Premium Edition and adds support for TD‑LTE CN networks while offering 256 GB of internal storage. It keeps the same display, battery, charging and RAM specifications as the standard Mi 12S Ultra 5G.
Compared with the other Premium Edition that ships with 512 GB storage, this model halves the available space but retains the full 12 GiB of RAM. Against the Standard Edition with the same 256 GB capacity, it steps up to 12 GiB RAM and the Premium Edition tier.
