The universal wireless charging solution should be compatible with aluminum alloy smartphones as well.

Charging with no cables can be convenient, but adoption rates have not been exactly smooth either. Currently, there are standards from the Wireless Power Consortium, the Power Matters Alliance (PMA), and the Alliance for Wireless Power (A4WP). As of June 1, 2015, however, the merger between PMA and A4WP means that there will now be one less wireless charging standard for the consumer market.

The Qualcomm WiPower wireless charging solution is based on the Rezence standard from A4WP. The organization had announced its Rezence standard back in December 12, 2013, which is based on magnetic resonance for power transmissions of up to 50 Watts through a distance of up to 5 cm. Additionally, Rezence allows charging of multiple devices of different power requirements.

With WiPower, mobile devices with metal bodies can also benefit from wireless charging. As Qualcomm demonstrates in the video below, both plastic and metal alloy smartphones and tablets should work. Currently, the technology can charge devices with an energy demand of up to 22 Watts and devices do not need to be aligned perfectly with the WiPower pad to begin charging.
