Apple has filed a patent application, for technology that will reportedly let the user set up wireless charging, with the US Patent and Trademark Office (USPTO). This feature is expected to be first incorporated in the iPhone first, followed by Apple Watch and then the iPad.

The long-range wireless charging, based on Radio Frequency (RF), is on the lines of wireless power developer Energous. This has been recently granted consumer safety certification for its wireless charging technology by the US Federal Communications Commission (FCC).

"The US Patent and Trademark Office published a pair of patent applications from Apple that relates to wireless power transfers and a unique scheduling system," Patently Apple reported on Friday.

"Apple's patent notes that the system is 'configured to wirelessly transmit power over the wireless power transfer link'," the report added.

However, whether this is the equivalent to "over-the-air" wireless transfer is still unclear.

Wireless power developer Energous and the Cupertino-based giant have been working together on wireless charging technology since 2014, according to tech website VentureBeat.
