Recently Wireless Power Consortium, consisting of such giants as Duracell, Nokia, and Phillips, approved standard for Qi wireless charging . This means that very soon you’ll be able to take any Qi-battery and charge it from any Qi-charger “by air” – without the wires and connecting terminals. But the craftsmen are not accustomed to waiting, and have added this new feature to HTC HD2.
Unfortunately, the usual battery of HTC HD2 does not support the new standard, so they had to disassemble parts from Palm Pixi TouchStone and use them to make the battery Qi compatible. But if the technology seems interesting, then it can be expected to start mass production of batteries and Qi-stations for existing devices. Video below, waiting for your comments after.
