The 2020s are increasingly shaping up to be the decade of foldable phones. Sure, they might not be mainstream just yet, but we're reaching the point where they're starting to look less like experimental products and more like phones that actually make sense to buy. Through continuous generational refinements, foldables have gotten more solid and have fewer downsides compared to standard, non-folding smartphones. And while Samsung arguably had a head start, with the Galaxy Z Fold 5 and Z Flip 5 being fifth-generation devices already, other companies have been following suit in recent years. Now, Xiaomi has released its latest take on foldables, the Mix Fold 3, and it's carrying a lot of improvements.
