Booklet foldables are an interesting paradigm. They’re unbelievably pricey, premium products that offer a whole new take on the smartphone form. However, the perceived wisdom is that you have to accept a few compromises to make it all work.Smaller batteries and less screen-on time due to the thin frame, performance throttling due to the cramped internals, trade-offs in IP ratings due to the hinge mechanisms, and a smaller, less well-equipped camera setup to avoid an unbalanced weight in hand. You name it, and there’s probably a believable excuse for why a $1,700 foldable doesn’t quite compete with the very best hardware specs you’ll find in an Ultra flagship that costs $500 less. Still, it’s a price some are willing to pay for the form factor’s less conventional perks.However, the new vivo X Fold 6 has upended that old adage, offering some seriously long battery life and impressive camera capabilities at a price that makes Google and Samsung look like they’re overcharging. Not only are the specs impressive on their own, but the X Fold 6 has exposed a serious lack of progress at the heart of the most popular Western foldable phones.
