The thinnest foldable phone is the Xiaomi Mix Fold 2 (unboxing).

 

The MIX Fold first generation hasn't seemed to have gotten the attention it merited ever since Xiaomi released it. Personally, I believe it to be one of Xiaomi's smartphone lineup's biggest flops. With a new foldable, Xiaomi just attempted a comeback in this market, and this is our unboxing of the MIX Fold 2.

Similar to other foldable phones, the MIX Fold 2's package is unusually large. The MIX Fold 2's premium status in the Xiaomi phone family is also demonstrated by the way the package is opened, which is in the form of a pull-out and flip-book. The MIX Fold 2 is revealed to us after removing this piece of cardboard.

It is even thinner than the iPad Mini when you consider thickness. It is also thinner than the majority of similar-style Foldable phones. Take three pennies and stack them to get an idea of how thin it is if you're still unsure. Additionally, it is one of the lighter folding phones, making it seem in the hand like a very small little tablet. It is slightly thicker and heavier than a typical phone when closed, but it is still within acceptable limits. The OPPO Find N and MIX Fold 2 are undoubtedly options if you want to purchase a foldable phone but need it to be sufficiently thin and light.
