Based on a report by cnet.com and Evan Blass on Twitter, Samsung phones could start using graphene batteries instead of lithium-ion batteries by the year 2021. Smartphones fitted with the graphene batteries will have significantly higher capacity, and it is able to be fully charged in under 30 minutes. Not only that, but it could also reduce the overall price of the smartphone as graphene batteries are rather cheap to manufacture.
