NEW YORK (TheStreet) -- Shares of Energous (WATT) - Get Reportwere higher in late-afternoon trading on Thursday as the San Jose, CA-based wireless charging technology company is believed to be working with Apple (AAPL) to integrate its technology into the company's iPhones, according to VentureBeat

Recent filings with the SEC indicate the Cupertino, CA-based technology giant may be testing Energous' "WattUp" wireless charging technology. 

Additionally, Energous has acknowledged in an SEC filing that it's working with a major customer, VentureBeat reports. Specifically, in its industry certification section of the filing, the company lists Apple compliance testing as a detail.

Apple has been exploring wireless charging technology for several years, but so far hasn't released a model that incorporates the technology because it's still too cumbersome, said Phil Schiller, Apple's senior VP of worldwide marketing, in a 2012 interview, VentureBeat notes.

As the technology stands now, it would still require the user to plug a device into a wall in order to enable wireless charging. 

Energous' wireless charging transmitter broadcasts waveforms to receivers and then surrounds them with a radio frequency that charges devices. The signals can travel as far as 15 feet and up to 12 devices can be charged at once, according to VentureBeat.

Users can pick up the signal through a mobile app that specifies when an Energous transmitter charges devices and how much power each device should get.
