The device combines a slim 5.02 mm unfolded profile with a 6000 mAh silicon battery and a Leica 200MP camera system, marking a significant hardware shift in the folding device segment.
Design and Hardware Build of the Xiaomi 18 Fold
Xiaomi positions the new device in the mid-range foldable segment by combining a compact flip layout with the expansive screen area of traditional foldables, according to Baonghean. The exterior display measures 5.38 inches, while the main interior screen spans 7.58 inches and is calibrated to a standard paper format to optimize readability. Physically, the device measures 5.02 mm in thickness when unfolded and weighs 219 grams.
Mechanical durability relies on a new generation Dragon Bone hinge structure paired with Dragon Crystal Glass 3.0. According to Baonghean, these protective materials provide drop impact resistance of up to 1.2 meters. The device is available in Nishino red, warm white gold, and black colorways.

The Xiaomi 18 Fold achieves an ultra-thin 5.02 mm unfolded profile while housing a large 6000 mAh battery through the use of advanced silicon battery technology.
Xring O3 Processor and LPDDR6 RAM Performance
The technical core of the Xiaomi 18 Fold is the independently researched Xring O3 AI processor. According to Baonghean, the processor platform reached a benchmark score of 5 million points on AnTuTu. Compared to previous models, multi-core CPU performance increased by 60 percent and GPU power rose by 85 percent.
Furthermore, the hardware architecture integrates the mass-produced LPDDR6 RAM standard manufactured by Changxin Memory. Baonghean reports that this makes the device the first smartphone on the market to utilize LPDDR6 memory, delivering high data transfer bandwidth to support complex artificial intelligence algorithms and heavy graphics processing.
Leica Optics and Jinshajiang Silicon Battery
Imaging capabilities continue the technical partnership with Leica. The triple rear camera setup features a 200-megapixel primary sensor alongside a 50-megapixel periscope camera supporting 3.5x optical zoom, as reported by Baonghean. Power management is handled by a 6000 mAh Jinshajiang silicon battery designed to support the dual-screen configuration over extended operational periods. The device also supports 67 W wired fast charging.
