Xiaomi's second foldable phone is only 5.4mm thick in tablet mode

Merely a day after Samsung's Galaxy Z Fold 4 launch, Xiaomi was quick to follow with a surprising punch. The Mix Fold 2 is the Chinese brand's second foldable phone, featuring a surprising thickness of just 5.4mm when opened — barely enough to house a USB-C port — and 11.2mm thick when folded. While Huawei's Mate Xs 2 is also 5.4mm thick when opened, bear in mind that it folds outwards instead and therefore lacks a secondary display, not to mention its 11.1mm-thick camera "column."
