Wireless charging, once a must-have feature for a smartphone, has fallen out of style largely due to slow charging times and competing wireless charging standards.

LG Innotek, a division within LG Corp. that develops cutting-edge tech components, has created a wireless charging technology for phones it claims is as fast as charging with a wired cable.

The 15-watt transmission module for wireless chargers can charge up a smartphone from 0% to 50% in 30 minutes. In comparison, it can take hours for many existing smartphones with wireless charging support to do the same.

LG says its new wireless charging tech charges phones three times faster than most wireless chargers on the market today that use a 5-watt transmission module.

The transmission module is also compatible with the Wireless Power Consortium and AirFuel Alliance's standards.

Samsung's new Galaxy S7 and S7 Edge support wireless charging with up to 15 watts, according to CIO. But the company's own "Fast Wireless Charger" only outputs around 6-7 watts.

Apple is rumored to be working on a different wireless charging technology — one that wouldn't require the phone to be placed on a wireless charging pad. The technology would allow devices to wirelessly charge over the air.

With new wireless charging innovations, we might finally be able to ditch wires.
