LG Innotek (subsidiary of LG) recently had a wireless charging breakthrough which will be coming to retail products soon. It's a wireless charging chip that can actually charge your phone's battery up to 50% in just 30 minutes. Their new tech is a 15-watt wireless charging transmitter, which is 3 times higher than typical wireless chargers.
The best part about this breakthrough is that it won't require completely new phone tech to work. It is actually compatible with the major wireless charging standards: Wireless Power Consortium and AirFuel, the alliance between PMA and A4WP (and a few others as well). LG plans to mass produce the tech later this year.
