Yep I read all and a lot about USB today, because currently I'd have to take out my battery to charge it. So I've been finding different ways to charge the battery, from repairing the micro-usb, to creating a new usb connection and wireless charging. So far it seems like Touchstone is the safest, although it only works with it's own charger. So if that charger goes missing, I'm doomed and have to order another charger. Creating a new usb connection seems interesting enough, but I'd really like to implement wireless charging. Not sure to go with qi, or touchstone.
