Nokia explains how wireless charging works on its new Lumia Windows Phones
The upcoming Nokia Lumia 920 and Lumia 820 are two of many upcoming Windows Phone 8 handsets, but they are the only ones to come with wireless charging and that makes them really stand out.

As you’ve probably heard, the new Lumias will use inductive wireless charging and now Nokia has taken to its official blog to explain the technology behind it. Basically, what makes it possible are two transmitter coils - one on the charging pad and another one on the back of the device itself.

From there on the transmitter coil on the charger generates a magnetic field used by the device for charging. Nokia is using the Qi (chi) global standard that is good news for compatibility across the globe. Nokia has perfected the charging pad so now around 80% of it is active and you don’t need to worry too much about precisely placing a phone on its place to charge it.

Sadly, it seems that you can charge only one phone on a single wireless charging pad, so if you plan on just throwing your home’s worth of phones on it, you won’t be able to. Check out the slideshow below to see how the whole thing will work out. The actual charging pads will be available for purchase separately from the phone.

Some one should stop this silly patent wars. Main of them are not invented by comapnies, they just were 1st at the patent queue window.

There is a wire to the mat. How is this wireless charging?

the purpose is to not connect the phone itself via cord, when charging.

just drop the phone -then the magic works.instantly

also useful for outdoors: coffee shops, lounges, any f**king table that has a wireless charging capability.see my point?

hey dexter_jdr, so not all phones can use this mat for W/L charging? oly phones which are meant for W/L charging huh

yes. as long as your phone has built-in wireless charging (lumia 920), you charge using wireless charging ports..

also dedicated accessories can be used for wireless charging aswell.. like the lumia 820, it has no built in W|L charging capability. but you can buy the interchangeable wireless charging back cover for it. sold seperately.

you dont have to plug your phone. just lay it on top of the mat. the mat doesn't need charging the phone does.

oh god 1st world problems

It's not new thing, it was invented years ago by N. Tesla. Sad that just now all his inventions starting to find there spots. What we could be using if they were developed at that time...

And I'm sure we'll see more of his inventions in our days.

All cell phones should have this technology.

@phonearena I guess it is a derivative of Faraday's law of electromagnetic induction.

Will this wireless charging mat work with any phone that allows wireless charging or will it only work with Nokia phones?

Sorry if that's a dumb question, just wondering whether different manufacturers use different methods to charge wirelessly and whether you could use that mat with the S3.

I believe it complies with Qi charging... So any Qi charging capable device should be able to benefit from Nokia's wireless charging products.

This should definitely become an industry standard. As innovative as Google is, I am surprised it didn't come from them first (out of the box capability). Of course I should not tarnish the heavily funded and very powerful R&D division of Nokia (no matter how they cut back). KUDOS.

But sometimes I like to use the device while charging it when the battery is low. I am charging my galaxy note 1 now while writing this comment. I think they should include wire along with wireless charge. you know that these smart phones require charging at least twice a day on heavy use. I charge my galaxy note 1, 3 times and not enough. Samsung offer an easy access to the battery swap but Nokia has no access to the battery. still I think the lumia920 is the best wp8 at this moment.

your story shows that your samsung device fails on battery performance.
nokia is not like that coz they perform great on battery execution... the wireless charging on 920 is just optional.buy the charging plate if you want.
but you still have the standard charging on 920.connecting a charging wire via micro usb.

I like the speaker because it's JBL NOT A BASS BEATS Speaker. JBL makes good quality speakers wonder if its compabitle with any NFC PHONES

yeah that jbl speaker is great + it has wireless charging on board..

which means if you have the lumia 920, you can play unlimited music because you just need to put your phone on top of the jbl, then it will charge!
