Wireless charging wastes a lot of energy. I'm not sure of the exact figures but I recall around 50%. Not a huge deal, on a personal level, for a plugged in charger (although if everyone in the world starts doing this it'll be more of a problem). However wireless charging from a battery pack is not ideal because the battery will have to be bigger. I already feel my phone is too big to be comfortable in my pocket, and I know it's even more of an issue for smaller people/women's clothing with tiny pockets. It's an interesting idea though.
