About Xiaomi Mi Mix Fold 2021 5G
The Xiaomi Mi Mix Fold 2021 5G presents itself as a foldable smartphone that features a secondary colour AM‑OLED display measuring 6.52 inches across. This outer screen delivers a resolution of 840 by 2520 pixels, providing sharp visuals for quick interactions when the device is closed. Its overall footprint measures 133.38 by 173.27 by 7.62 millimetres and it tips the scales at 317 grams, giving it a substantial yet manageable feel in the hand. The device supports a single SIM card, keeping the connectivity setup straightforward.
Under the surface, the phone runs Google Android 11 and is equipped with 12 GiB of RAM, ensuring ample memory for multitasking and demanding applications. Power is supplied by a 5020 mAh battery, aimed at supporting extended usage between charges. These specifications combine to create a device that balances a distinctive foldable form with solid performance capabilities.
The Ceramic Special Edition upgrades the memory to 16 GiB, giving noticeably more headroom for multitasking and demanding apps compared with the base model’s 12 GiB. It also features a ceramic finish that sets it apart from the standard glass or metal build, and its weight increases slightly to 332 g while keeping the same foldable dimensions, battery capacity, display and Android 11 software.
Relative to the Premium Edition, which also offers 512 GB of storage, this variant provides the additional 4 GiB of RAM and distinguishes itself with a ceramic rear rather than the premium’s conventional material, making it a higher‑memory, more tactile take on the same foldable platform.
