Report: LG develops smartphone that uses magnetic resonance charging
Business Korea is reporting that LG has produced a smartphone that uses magnetic resonance technology to charge the phone's battery from 2.75-inches away and closer. While magnetic induction requires a handset to be placed on a mat in order to power up the juicer, magnetic resonance allows a phone's battery to be powered up while away from the charger. Recent advances have allowed that distance to widen from .78-inches to the aforementioned 2.75-inches.

Additionally, the magnetic resonance charging can reach 7 watts. That should be fast enough for even the most impatient power user, and should allow the latter to fully charge his/her handset (or come close) inside an hour.

Some smartphone manufacturers are said to be working hard on developing handsets that use the magnetic resonance charging technology. It is expected that companies like Meizu, Oppo and Huawei will launch phones with magnetic resonance charging capabilities as soon as next year. Business Korea's report says that LG has already finished the development of its own phone sporting the charging technology, and is deciding when the best time is to release it.

Neat! Impractical...but still neat!

I just wonder if there are any long term effects on human health because of this. I mean you can think of this as a smaller version of an MRI machine. Yes it's not anywhere near as powerful, but still there is a reason we as humans don't expose ourselves to MRI machines on a daily basis.

MRI is a very safe procedure. The strong magnetic field itself does not hurt people... You are confused it with CT SCAN which use x ray radiation... The only way it's harmful if u have some metal in your body

I think this wireless charging is a total waste of recourses! why don't we just plug the damn thing and charge it the fastest possible?! I mean the damn still has to be connected to a power outlet! instead of that just focous on developing a better battery technology!

But if the distance will improve in such way that you will be able to keep the phone in your pocket and charge when you are in a room with wireless charger. Evolution can take you where in the bus, subway, restaurants you can charge the phone just because you entered there.. So I don't see it as a waste. More over technology can be applicable not only in mobile phones world. I like LG more and more.. they are really trying to innovate and implement in the past years

Your suggestions are just not feasible and show a lack of understanding of the science involved.

Wired internet is also faster than WiFi, wanna plug an ethernet cable in? Not quite an apples to apples comparison but it shows what people will accept for convenience.

I already see phones hovering over a magnetic platform while charging. Symilar to those new floating speakers pretty cool :D

One thing I want them to make is some portable wireless charging pouch. Having a power bank with some cables are cumbersome and messy.

But will it work with metal phones?
