The problem with wireless charging is the same as with any wireless power transmission - it's not directed. How much of the electricity goes into the actual device, vs how much radiates out in all directions randomly?
Wireless charging devices basically have this pad that's larger than the phone that you have to put the phone on to charge it. It's "cool" but it's not an improvement over having a cable, the charging base needs a lot more materials in it's construction, uses more power (because rather than piping the power straight into the phone by cable, you're piping power into the base by cable, then radiating it in the hopes some gets into the phone) and the phone needs to have a receiver (an antenna basically) for the power, which adds bulk to the device. And it's actually harder to move the device around when it's charging, because you have to keep it on the frikkin huge base rather than just make sure the cable doesn't fall out. Plus, it doesn't eliminate the need for the charging socket on the phone anyway, unless you want a phone without any data / USB port.
So wireless charging phones are a step back: they're the gass guzzling SUVs of the smartphone world, in a time when we really should be looking to reduce our footprint on the environment. I really dislike any "improvement" that's inherently lazy and wasteful. And by implication, only for elite wealthy westerners: because if every smartphone user has this (~6 billion subscribers worldwide now) it would be an ecological disaster. So it's like "wow I love this invention, for me, as long as all those other people don't get it and fuck things up".
