Today, a blogger I Bing Universe posted a photo of the thickness comparison between Samsung Galaxy Z Fold 4 and Xiaomi MIX Fold 2. As shown in the picture, the Xiaomi MIX Fold 2 is thinner than the Samsung Galaxy Z Fold 4 in terms of single-sided thickness and hinge thickness.
Specifically, the thickness of MIX Fold 2 is only 5.4mm, and the thickness in the folded state is only 11.2mm, which is comparable to the iPhone 13 Pro Max wearing a protective case.
In contrast, the thickness of the Samsung Galaxy Z Fold4 is 6.3mm, and the thickness of the body in the folded state reaches 14.2mm. In terms of weight, the Xiaomi MIX Fold 2 is also slightly lighter than the Samsung Galaxy Z Fold 4, the former is 262g and the latter is 263g.
The reason why Xiaomi MIX Fold2 can achieve a 5.4mm ultra-thin design is that this folding screen uses a self-developed micro-droplet shape hinge.
Through the zero-welding integrated precision process, the number of rotating shaft parts has been greatly reduced to 87. At the same time, a customized miniaturized dumpling chain mechanism and a variety of high-tech materials are used to reduce the weight of the single rotating shaft by an astonishing 35% compared with the industry average, and the thickness is reduced. about 25%.
With the support of the precision hinge, the unilateral thickness of Xiaomi MIX Fold 2 is almost the same as that of the Type-C port. Lei Jun, the founder of Xiaomi, chairman, and CEO of Xiaomi Group said that “this is the thickness limit of a smartphone. The machine is currently on pre-sale, and the initial price is 8,999 yuan.
