Battery life is one of the few aspects of a smartphone that nearly everyone wants to see improved. Multiple companies have announced ways to lengthen a phone's battery life and Samsung is working on its own battery extending technology. A silicon anode and graphene layers are used on a new Samsung lithium-ion battery to extend battery life.

Samsung has already tested some of these new batteries and reports they are between 1.5 and 1.8 times as dense as current batteries. That could result in a meaningful extension of battery life.

Research is still taking place and that means there is no reason to believe Samsung is including the new batteries in the Samsung Galaxy S7 or another upcoming phone.
