Wireless Charging

To fully understand how wireless charging works takes understanding the concept of an electromagnetic field and electromagnetic induction. Electromagnetic induction is an energy transfer system, meaning that it can be stored or used.
Think of a person making waves with the rope, the other person will receive the waves as they travel down the rope. This is like electromagnetic induction: a force sends energy from one point to another. The base unit (powered by electricity) transmits energy to the smartphone via electromagnetic fields. The sensors on the smartphone recover the energy and channel it to the battery for storage.

Qi is the most popular wireless charging technology. It is not restricted to a particular manufacturer. Qi uses electromagnetic induction charging and magnetic resonance technology.
