Samsung is reportedly leading the race to build foldable smartphones with the development of a curved battery that it can produce in large numbers.

The Korean conglomerate is said to have figured out a way to make large-capacity batteries that can store between 3,000mAh and 6,000mAh of power, reports ITHome. If the news is accurate, it’d be a far cry from the 210mAh flexible cell design that the Samsung SDI subsidiary came up with four years ago.
