Samsung is working on graphene ball batteries. They are looking for a 45% increase in capacity and five times faster in charging. A smartphone battery can have the capacity of what is now in laptops. I also like the idea of not relying on scarce materials. If it pans out, it will be years in the making though.
Could this be a device utopia, or will we end up getting use to bigger capacities and start complaining all over again?
