Our smartphones work on a rechargeable battery. Most of the smartphones that are present in the market use this technology. This form of technology is much more affordable and long-lasting as compared to the previous format and the past options. 

For charging, mobile phones usually have separately made slots in the Mobile Phone Cases so that the wire can be attached properly. 

But now a new form of charging has been introduced in the market. It is called wireless charging. No need to get involved in the struggle and hustle of wires. Now just charge your phone through this latest surface technology.

The phones are charged using the phenomena of electromagnetic induction. There is a conductive coil (usually a copper coil) present in the phone at the phone. 

Due to a charging magnetic field, an electric current gets induced into the conductive coil. As a result, the battery at the back gets charged it. 

To make it even easier, the phone can easily get charged even if there is a cover at the back.
