Samsung was quick to adopt wireless charging in its Galaxy phones, but the technology’s popularity has reached an all-time high thanks to its adoption in apple’s iPhones last year. It is mainly available on high-end phones with glass backs — metal and wireless charging don’t mix.

Not every flagship has the technology, but more and more manufacturers are hopping on the bandwagon.

Wireless charging is the transfer of power from a power outlet to your device, without the need for a connecting cable.
