Until now, you've had a choice: a smartphone with a sleek metal chassis, or one that played nice with wireless charging standards. Those days may be over. Qualcomm just announced that its WiPower charging technology can now power smartphones, tablets and other devices with metal cases. The updated standard is already available to device manufactures and licensees, the company says. Everything else about WiPower seems to be the same: it still charges at the same rate and still meets Rezence standards -- it's just doing the same job better now. Good enough.
