Two foldable were released these days. So that’s logical that users are endlessly comparing them, trying to understand which of them suits their needs better. Today, a Weibo blogger made his comparisons as well. He put the Xiaomi MIX Fold 2 next to the Samsung Galaxy Z Fold 4.
As we can see from the photo, the Xiaomi MIX Fold 2 is thinner than the Samsung Galaxy Z Fold 4 in terms of single-sided thickness and hinge thickness. But this should be obvious even without comparison because the Xiaomi model is promoted as the world’s thinnest foldable. Specifically, the thickness of Xiaomi 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.
The reason why Xiaomi MIX Fold 2 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, it uses a variety of customized miniaturized dumpling chain mechanisms and a variety of high-tech materials to reduce the weight of the single rotating shaft by an astonishing 35% compared with the industry average. The thickness is reduced by about 25% as a result.
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, said that “this is the thickness limit of a smartphone.”
It’s also interesting to know that these two have almost the same weight. The Xiaomi MIX Fold 2 weighs 262g, while the Samsung Galaxy Z Fold 4 is 263g.
