it's only digital signal transmitted from one to the other phone via nfc . Only modding antenna , connect it as a charger .

Yes then it has to continue recharging kable ago ;-) 
keep that's probably indulged only the Lumia 920,.,., ****..., But cool thing

I believe you are confusing “Inductive Charging” with NFC.

Wireless charging of mobile devices is picking trip, the upcoming Nokia's flagship Lumia 920 about to be factory-Qi-compatible. Now Renesas announces three semiconductor devices that use the wireless store up to 10 centimeters distance antennas, which are also suitable for Nahfunktechnik NFC. For samples of the three controller chips will each Renesas have $ 6 - that would be for the series products but probably too much. The mass production is scheduled for the 2013th
The tiny controller chip NF20 assumes the NFC communication, the transmitter controller controls R2A45801 through MOSFET RJK1028 to the transmitting antenna and in the mobile device the R2A4570 sits as a receiver. It includes a charging circuit for a single lithium-ion cell (3.7 volts), but also provides DC voltage to the device, as well as 1.8 to 3 volts for the RF20 on the receiver side. Also assumes the R2A4570 switching between different charging sources such as (micro) USB port or charger input.
Renesas specifies the communicable charging power not exactly, probably it is not higher than that of Qi, ie less than 5 watts. Thus, the loading of a typical smartphone battery would last with 5.5 Wh capacity significantly more than 1 hour, if we include loading and transformer losses. IDT has therefore announced in March a Qi-compatible IC couple that is in a proprietary mode create about 7.5 watts.

NFC is very similar to BT... At least when transferring files, it works only as a "hand-shake" mechanism...

How it's a magnetic communications antenna possibly going to charge by transferring electrons?
It s not impossible, theoretically, you'd need some heavy modifications and charging times would be in excess of 7 years.

let's see if anyone ever tried it.,,. if it would be possible if it was not, unfortunately, a beautiful dream
