Chinese smartphone brand Honor launched what promises to be the world’s thinnest foldable phone—just 4.1 millimeters thick when unfolded—on Wednesday as it seeks to regain lost ground in China’s competitive phone market.
The Magic V5’s thinness is made possible by innovations in its silicon-carbon battery, which stacks cells just 0.2 millimeters thick to create a battery that’s as thin as a bank card. The new phone is also light: At just 217 grams, the Magic V5 weighs less than the iPhone 16 Pro Max.
