About Xiaomi Mi 12X 5G
The Xiaomi Mi 12X 5G feels comfortably compact in the hand, measuring just 69.9 mm wide, 152.7 mm tall and 8.16 mm thick while weighing only 176 grams. Its front is dominated by a 6.28‑inch AM‑OLED panel that delivers a sharp 1080 by 2400 pixel resolution, offering vivid colours and deep blacks typical of the technology.
Inside, the device pairs 8 GiB of RAM with a Linux‑based OS version 4.19.113, providing smooth multitasking and responsive performance. A 4 500 mAh battery supplies the power needed for daily use, and the phone supports a single SIM slot for mobile connectivity.
The Premium Edition steps up to 12 GiB of RAM and runs Google Android 11. It is offered in the Chinese market with 256 GB of storage and carries the Premium Edition badge.
This sets it apart from the other listed variants, which combine 8 GiB RAM with either Global or Chinese regions, 128 GB or 256 GB storage, and lack the Premium Edition designation.
