Ok so I know many people are waiting on wireless charging. My question is, is wireless charging already here just sitting under our nose?
I haven't found any threads talking about this, so I apologize if I am wrong, but the NFC antennae is built into the battery. Could this also be the wireless charging ability unleashed by a powermat?
From: http://www.itproportal.com/2012/03/23/update-duracell-powermats-wicc-power-matters-alliance/
"Duracell Powermat's key message is that adding wireless charging is now easier than ever before. The wireless charging functionality could be built directly in the battery, as a WiCC card inserted by the manufacturer in the phone or available as an off the shelf after market accessory."
They have also shown their WICC card in the S2, so we know they are pals with Samsung. Also, Powermat has kept saying "coming this summer" for their new line of products. Perhaps the "delay" with the wireless charge kit for the S3 is actually a delay on the part of Powermat getting their new product line.
So I ask, once again...If you set the device on a powermat as is...does it charge?
No comments to this? I thought someone would at least have a powermat to squelch any thought of this I had.

That's a fantastic question and would love to know myself.
I suspect the two pins to the left of the battery are for the wireless expansion. You could be right through.
Any update on this?
These are going really CHEAP http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=360471423929&ssPageName=ADME:X:AAQ:GB:1123
ADC
it could be on the optional back cover , the two pins are for the connections , also there are claims that it can charge further away then sticking it on the dock or charging mat , i find it quite pointless if charging has to stationary , i rather just plug it in into my charger
The two pins next to the battery seems a good shout. Means Samsung can sell compatibility battery doors.
Anyone got a schematic and know how to follow the PCB wiring to see if the pins feed the charging circuit?

No, NFC is not used for wireless battery charging.

Wireless charging cant get much better than that
I've heard banter about wireless charging over time, never really looked into it,
Being part of the device such as DNA will they be selling what accessory to allow this? a Mat or ?

Case with wireless charging
Can we have a case on the device when we're wirelessly charging or do we have to repetitively take the case on and off when we charge? That would be a big let down if we had to. Thanks in advance.

once i find a case that will fit i will give it a try, since the wireless pad is on my to purchase list tomorrow
Sadly, what I've been reading is that it depends on the case. Wireless charging seems to be out for the outer box users out there.
How about disruption?
If I for example, took my DNA, Keys, change etc out of my pocket and just plopped it all down on the charge pad, would the keys/change effect it's ability to charge?
Is it induction? Using Magnetic Fields etc...
Is it using the same wireless charging standard as the Nexus 4?
Correct me if I am wrong, but the DNA (at least) is using the Qi standard (http://en.wikipedia.org/wiki/Qi_(inductive_power_standard)), same as Nokia's new line up. But IDK about the Nex4.
Edit: seems like they both use Qi after all. Standards are great when they actually are used, haha. But hopefully this means the price of chargers will decrease. My only hope is that there are magnets on the back of the DNA to hold it in place, like on the Nex4.
I'm quite sure that the "wireless charging" technology is not wireless power. It's just a way of charging where it passes through the back of the case and it's at such a low voltage that you don't have to worry about touching the mat yourself. It's called wireless because it doesn't use an actual wire/cord, but calling it "cordless charging" would have been more accurate.
So I'd assume that most cases would block it, unless they are thin enough for the electricity to easily pass through. Even if it does charge, the case might slow it down.

actually the surface of the charger is not electrified at all. Its etromagentic which means the charge or field origninates from within the device and therefor there is absolutely zero danger due to physical contact and the case only has an effect based on the distance it moves the inductive coils in the phone from the base station. It cannot slow the charge unless it somehow has a faraday effect blocking out the electromagnetic field. http://en.wikipedia.org/wiki/Wireless_charging

excuse spelling errors
It's like an induction hob for a kitchen cooker.
There will be a magnetic coil in the pad that, once the phone is placed onto it, will complete an electro-magnetic circuit and power the phone. iirc...
But I remember reading about how it's very different technology than "wireless power" and that you couldn't use this to power something like a PS3 because it would be dangerous and shock other things, where as something like MIT has done could power a room full of devices and you wouldnt have to worry about things getting a charge that weren't meant to. Could be wrong though, or might have been on older "wireless charging" units.
First there are many forms of wireless charging (ie. wireless transmission of electricity). In the context of the DNA (and other phones: Lumia's, Nexus 4, etc.), the method used is "Inductive Charging" (the Qi standard linked in my previous post). In this situation, the only damage that can be caused is via magnetic interference; for example, the consortium supporting Qi, posted some guidelines that hint at potential interference (AM radios, key fobs, etc.), but I don't think that this is a severe problem. Keep in mind that inductive charging has been around for years; it has just only recently become efficient enough to use (practically) in mobile devices.

The ps3 wouldnt pull a charge from it period. It must have an inductive charging coil inside of it to conver the AC electromagentic field to something useful otherwise the charging pad would have little effect on it other then subjecting it to an EM field. There is no actual physical connection established between the device and whatever its charging outside of the EM link thus "wireless" charging.

Well, I meant something as powerful with an adapter to receive the power, not putting some coils next to it and hope for some magic to happen if you give them enough power. lol
lulz no harm no foul! http://www.youtube.com/watch?v=R617vPlqinI letsw just start tearing things apart when these phones ship and building these! itll be the calling card of the DNA community =D

Currently the Qi standard has provisions for both "low" and "medium" power devices. Low caps out at 5W (I believe), suitable for mobile phones, etc. But the Medium power spec does hold the potential for larger more energy consuming devices.
Keep in mind, however, that the transmission process is lossy, and you only get 60-90% efficiency (okay for small devices, harder to justify for a PS3 ).
I have a wireless "Inductive" type charging mat for my Wii controllers and it works with the rubber cases still on them
Hi all,
I'm posting this in case anyone else purchases this gear and thinks they can use it like the original battery that comes with the Note 3.
There is another post in this forum that talked about a 50% off code until June, so I bought this:
http://www.samsung.com/us/mobile/cell-phones-accessories/EB-K800BUWESTA
Even with shipping/tax, it only came out to ~$31. I thought great deal.
It arrived and I noticed that you can't use it like you would the original Note 3 battery where I stuck a Qi-enabled sticker on it and could use it to wirelessly charge my spare battery when the main one runs down, figured I'd just buy another Qi-enabling sticker.
Thing showed up and it's NOT Qi-compatible. Meaning, it has no contacts on it that let me attach a Qi sticker. Not sure if it's by design that way but just thought I'd provide a heads up in case anyone else is looking to buy this.

There is two ways to do this,
1 modify the unit to support qi by adding a receiver inside.
2 use a USB receiver or a USB dongle.

1. Are you planning on opening up the battery to do this? Sounds like a lot of work and possibly ruining the battery if you screw it up
2. If you use a USB receiver, aren't you then completely ignoring the point of having wireless charging? I don't think I understand #2 completely.

1 you can open the battery charger that come with the battery and put a qi receiver inside, the battery charger then can be placed on a home transmitter.
2 connect a USB qi receiver through the USB port on the battery charger.
If you actuall want just the battery with qi built in, it's only available for the S3, S4 and note 2, if it's not qi, but supports wireless charging, other batteries are available for older phones models.
This is the best mat you can find right now.
The Powermat by Duracell works well and charges just as fast as the USB charger or the tablet dock . I picked one up on amazon brand new for about $18 ( plenty still around
I picked up the 4s and portable charger bundle for a steal. This is using the standard backplate that came with the phone. Many cell phone reps will tell you the phone doesn't come standard with wireless charging and try to sell you the folio as a "wireless charging bundle" for $70,don't be fooled!.
Alignment is good, natively the Duracell branded cases and portable charger have a magnetic pull to the phone to keep it in place. When placing the PadFone on the plate there is no magnetic pull. Make sure you lay evenly. The wireless charger will make a beep to let you know it has a handshake with the device.
Works flawless so far, no complaints.
Update #1 Turns out the Padfone X is only PMA compliant, This wireless charger is apparently one of the only ones available. There are different styles of powermat available. But no Qi compliance.
Update #2 This kit also came with the iPhone 4/4s adapter and a PowerBar, the power back can be attached to either a Padfone Tablet station or the Asus Bluetooth Padfone keyboard to provide "passthrough" charge.

Thanks for posting this review! I just ordered the exact same thing from Amazon yesterday and I wasn't sure if it was going to work. I was completely skeptical since just the Powermat is normally $50 through at&t.
Grab one at that price while you still can, less than $20 got me this whole set

Thanks for the heads up. Just picked up my new padfone X tonight after my beloved skyrocket fell and broke the screen. The rep thought the same thing about the wireless charging that I needed a wireless case. I asked to test out the 50 dollar duracell charging pad and sure enough "beep" and I was charging with just the phone out of the box. Nice find. This is a win win cause I also have an iphone 4s for my afterhours phone support for my job. Utter win here.
Thanks again.

Powermat charges fast but alignment is finicky
I also bought the iphone 4 powermat bundle from Amazon. I do like the audible and visual confirmation you get when it starts charging the device. Also it beeps when the device is fully charged. But overall you need to place the phone just right on the pad otherwise it beeps on and off and you end up taking extra time just to make sure it's charging. I owned a Nexus 5 before my Padfone and QI charging is a lot better you just drop the phone on the pad and it charges no problem never had to adjust the phone for it to charge.
But I waited forever for the Padfone to hit the US, so I can live with the charging issue.
After a while you figure out the sweet spot for charging hence the phone doesn't magnetically lock to the powermat, but when you connect, you'll have a full charge in no time
I also purchased the Duracell Powermat and it charges the phone fine, however one problem I have is that it seems to Overcharge the phone. I know this because of two things
1. "Battery Doctor" App reports that the phone had been overcharged
2. Phone is very warm/borderline hot to touch when I pull it off the charger in the morning
Has anyone else experienced this problem? I am concerned because overheating shortens the battery life of these phones so I want to prevent that. this does not happen when I charge via USB.
Battery doctor app is not a good representation for phones that support qi or pma charging. The phone will get warm, but not alarmingly warm. The science of contactless charging.
These are still available for under $20 with free shipping, looks like. A great buy for sure.
I received mine before I ever even got my PadFone X. With the issues arising theoretically being theoretically linked to charging the phone and station together for long periods, this frees up the included charger to charge the station by itself.
Can't thank the OP enough for passing on this find!
Just my two cents, but....

I have an old Samsung Qi wireless charging pad, and my Padfone S works with it. I will admit, the powermat charger is much faster - but Padfone S does support Qi chargering pads. Not sure about Padfone X.

I'm not noticing this issue with my Padfone S. In fact, my old Samsung phone (Qi standard) did get warm, but Padfone S doesn't.
For that matter, my Padfone S doesn't heat up when I have it tethering a wifi data connection to my laptop or other portable devices. I've only felt my Padfone S heat up on 2 occasions - both of which I was in a dead zone and the phone was powering up the antenna to try to get a signal.
Hey guys! Bought the official samsung charging pad today, for novelty factor more so then anything else if im honest! It was €55 to buy online here in Ireland (which is crazy money) but i got it along with a case for only €40 as part of a deal so i thought why the hell not. It came without a cable so naturally i assume i must use the fast charge cable with it? Here are a few questions i have.........
If using the fast charging cable with it , does that mean i will be getting fast charging capabilities from it? (iam assuming not)
If its generally not a good idea to use fast charge plugged in over night then does this apply to the wireless pad in conjunction with the fast charger?
And lastly. Can i run the cable from the usb port on my computer or does it have to be plugged in to a socket when using the wireless pad? The answers may seem obvious but just asking none the less! Not taking any chances with this baby ha
I have four of them. Two of the small rectangular ones from last year, and two of the newer round ones from this year, so I'll take a stab at your questions.
If using the fast charging cable with it , does that mean i will be getting fast charging capabilities from it? (iam assuming not)
I have not seen, nor did I expect to see, any difference using a fast-charger vs. standard. As such, I only use standard charger adapters for wireless duty.
If its generally not a good idea to use fast charge plugged in over night then does this apply to the wireless pad in conjunction with the fast charger?
My S6 Edge stops charging while on either version of the wireless charging pad, once it reaches 100%. The light on the (newer, round) pad goes from blue to green once it has reached this point.
And lastly. Can i run the cable from the usb port on my computer or does it have to be plugged in to a socket when using the wireless pad? The answers may seem obvious but just asking none the less! Not taking any chances with this baby ha
Unless your PC can source 2A from the USB port, then, no, you cannot use your PC USB port to power the wireless charging pad.
Any idea where i could get a longer geniune samsung charging cable so? I bought the wireless pad for use at a desk but the cable on the fast charger is too small to reach from the socket to the desk! I would need the cable to be at least another foot or two longer
Questions belong in Q&A, not General.
Thank you.
I have a question I'd like to add!
I've never used wireless charging before, can you use it on the s6 edge with a case on the phone? Does this impede the wireless charging? Thanks!

Impede? Yes.
Any distance between the surface of the charging-pad and the back of your phone will impact the wireless inductive charging. The less, the better.
Also, obviously, any case that includes conductive materials will be a non-starter.
That said, my Speck case and my wife's (brand unknown at this moment) case work satisfactorily with both the Samsung round and rectangular charging pads. I have read that there are people that have had poor wireless charging experiences with some (probably thicker, more rugged) cases.
Searching should find the specifics.
Should I use the one by Samsung so as not to degrade the battery?
or it doesn't matter at all?
What brands would you recommend?
It doesn't matter. I use 2 official wireless chargers and one 3rd party pleeson brand.
Not one difference.

I don't know, after the latest system update on verizon my 3rd party wireless charger stopped working. Only charges about 20% then stops.
Shouldn't be. But I'm waiting for the new convertible one to be on sale.
No problem with my choetech stand fast wireless charger.
The S8 supports most wireless chargers, but it's best to make sure the charger you pick was made for at least the S7 if you want to get the wireless fast charge function.
The transmitter for the wireless charger also needs to line up with the right spot on your phone or it might not make a proper connection. I had this issue with my S6 where the spot on the phone was lower than the charger, so I had to put something below the phone to line it up with the charger.
Just saw this fast wireless charger deals on Slickdeals! Hope useful for you: https://slickdeals.net/f/10178316-choetech-qi-wireless-charging-stand-for-galaxy-note-5-s8-s7-s6-edge-and-more-16-ac-fsss?src=SiteSearchV2_SearchBarV2Algo1
I snagged the official 2017 wireless charger for a steal at best buy. I showed them an online add from cdw and they took it!!! Only cause it was the last one in stock and they wanted to slang it quick. Lady at the register was surprised I got the deal.
Bought a Tronsmart Chocolate Bar charger. Works just fine, though I plan to move the charger circuit (replacing the microUSB port with a soldered USB cable or even a QC3.0 power brick) into a 3D printed phone stand.
I have a normal diy wireless charging coil. It heard up more than it charges.
I bought a Black Web wireless charger from Walmart originally as a temporary charger until we got in the Samsung one. Honestly not going to bother. It works well enough, no heat and holds the phone at 100% once charged.
I looked around on Amazon and it seems to be identical to several they sell, just different branding.
I'm content at the moment, was only $20.
My Nexus 6 charger worked only at normal speeds. I like the magnet in it so ordered magnets to attempt to modify the Blackweb charger. They aren't necessarily needed, just something I want to attempt.
