NTT DoCoMo and Panasonic Mobile Communications have successfully experimented with a contactless recharging mechanism by having a FOMA phone recharged by having it placed on a special recharging pad.

Using electromagnetic induction to send recharging electricity to the battery, this contactless electricity is delivered through a pad that has a coil for transmission, and a reception coil inside of the handset itself.

“[The technology] can be supported by just changing some of electric wiring and the battery cover” (DoCoMo). It is time consuming, however, as it took 33% more time than current charging methods to charge the battery of the P900i using this system. This is about 33% more than the status quo.

A great caveat would be this – since the connection is contactless, space usage is minimized and can be used on any shape of handset, thus making the system waterproof as well.

At point of publishing, NTT DoCoMo have absolutely no idea when the system will be commercialized.
