While the core mobile technology constantly evolves, other technologies associated with it takes time to bring in something ground breaking. Same was the case with wired mobile charging to wireless induction charging technology shift. The traditional wired chargers are now being replaced by wireless chargers that is powered by what is called Induction technology.
Inductive charging uses the electromagnetic field to transfer energy between two objects. A charging station sends energy through inductive coupling to an electrical device, which stores the energy in the batteries. Because there is a small gap between the two coils, inductive charging is one kind of short-distance wireless energy transfer.
