What makes Samsung’s wireless charging solution stand out is the fact that charging coil is 40% thinner, and is attached to the inside of the battery cover. This would allow Samsung to keep on making very thin devices, but beef them up with wireless charging capabilities.
We can’t really say which exact products would get this new module, but one obvious candidate is the Samsung Galaxy S III. The S III was touted to come with wireless charging back in early 2012, but this elusive charging never materialized. Of course our wishful thinking immediately hints a future S IV is also a likely candidate. That’s just a speculation though. To know the reality, we’d just have to wait.
