Wireless Charging Is Here. So What Is It Good For?


The technology, also known as magnetic induction, is a relatively new feature for powering iPhones and popular Android phones.





Besides getting bigger, smartphones keep getting — for lack of a better word — glassier. From front to back, the bodies of many of the newest smartphones are composed of glass.

The trend is not part of a broad conspiracy to make you shatter your phone so that you buy a new one. Instead, glass lets energy pass through the phone so that it can be charged wirelessly.


The technology relies on magnetic induction, which involves using an electrical current to generate a magnetic field, creating voltage that powers the phone without your plugging a wire into it.
