I use the Nokia qi charger with nice but it's slow as crap because it's only 750 mah output instead of the standard 1.75A output. This is with using the flip folio case.

I see you have the AT&T version. Does it work with the regular backplate on? I haven't been able to find a clear answer if it does or not.

Yes the AT&T back plate has the conductor on it. I've seen it in videos. You can also pull out the pad carefully from the quickcover and stick it to the standard cover in the correct place and that gives your wireless charging.
I thought the att version supported wireless charging out the box?

Does it charge as fast as our 1.8 amp wall plugs?
I'm using the Nexus 4 Wireless Orb. Kinda pricey @ $70 (after tax & shipping) directly from Google (or from Amazon) but it was worth it to me because it's angled so I can see the LED notification while still laying in bed as it's on my night stand. Also, since it's the wireless charging standard (Qi) to go by for awhile I figured I'll be able to use it with the next few phones after the OG Pro. If you have a non-slippery case (I've got a TPU one) then it should stay in place. However, I've heard otherwise based on reviews on Amazon & in the Nexus 4 forums with a slippery case (Incipio for example) or using the stock backplate (or OEM flip cover). Google states it'll take 4-hours (output on the Orb is 1.0-amp) to fully charge a Nexus 4 & it takes ~4 - 4.5-hours to fully charge an OG Pro. Charging time's insanely slow but I figured only time I'll be using the Orb is when I'm sleeping so I don't mind the extra charging time.
I also use the LG Electronics WCP-300 Wireless Charging Pad. In fact, I bought 3 of them! I keep one at work and two at home. They work really well and the top is made of soft rubber, which is pretty cool. I bought them from Amazon for $49.99 each and now I wish I had known that Verizon.com had them for $40.00...oh well.
I'm using the LG WCP-300 and contrary to some previous posts, the AT&T OG Pro (E980) does wirelessly charge with the standard back. The flip/quick cover will also charge but I don't like those covers. (Got one for free from AT&T for pre-ordering the OG Pro but I seriously doubt I will ever use it.)

I am using the LG model WCP-300. Works great. But I have noticed that the charging light on the pad continues to blink even after the percentage is at 100. I don't get the fully charged indicator in the status bar either. When I check the battery status in the phone settings it says that the battery is at 100 % also. Strange. Does anyone else have this issue?

When the motor activates and moves the charging coil, do you see lights moving on the pad's surface, or are the lights that are shown in the ads just to make you realize that something is moving unseen, underneath the surface?
Any idea how much juice this thing puts out? Does it charge faster, slower or the same as the G Pro's plug-in charger?
When you put two phones on the pad, I realize it will charge the first one that was placed, but will it automatically then move on to the second phone, or do you first have to switch it into some special mode to alert the charger that there will be a second phone to charge after the first one is completed?
On a slightly different tack....Don't know if it's any good, or if it's even out yet (I first saw it on Kickstarter), but TYLT has a pretty cool looking QI charger with 3 coils inside that supposedly allows you to place the phone on the upright, angled, stand in either portrait or landscape orientation, without the need to align coils to ensure that it charges.
All their products look cool, but I have no idea how they perform in comparison to other manufacturer's goods.

Mine is the opposite- I get full charge indicator and the light stops blinking. Whats more.. if I put the phone on the pad while it shows 100%, it wont do anything.

Fixed the issue by returning it. The replacement works as expected. Must have been defective.
I just got an S3, and was excited about the ability to use wireless charging. While looking for QI gear on eBay, I ironically stumbled across an item that will add that very same feature on my old SII, without any permanent hardware mod needed.
The item in question is this: http://www.ebay.com/itm/200963522572?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
It's basically a QI charging inlay thing that has a very tiny microUSB connector, allowing you to connect it to essentially anything that charges via microUSB. I bought one just to try it out, and sure enough, it works like a charm with my old S II. I have a cheap (but great) TPU case on my S II, and the QI inlay fit absolutely perfectly between the case and the phone's actual back cover.
I used the SII for more than a year and a half, and I frankly hope that this was just invented a few weeks ago, as I hate to think that wireless charging for my S II was $16 away all that time >.<
Hey, *thanks* so much for this, it is just about exactly what i was looking for (and not able to track down on the net). Much appreciated and can't wait to try it out on my SGS2!

With "Android Tuner Free" you can see the incoming mAh when charging (at battery stats).
With standard wallcharger from samsung I get ~640mAh
Does anybody got the incoming mAh stats about wireless charging?
Anyway, I think cable is better because you can move and use your phone.

Hi folks,
I've been looking into wireless charging because, I thought, I could set up my phone to charge wireless; that is, across the room, for example. However, upon closer inspection, it looks like I'd be relegated to setting the device on a "base" in order for it to charge. Now, perhaps I was naive (or dumb) in thinking that I could chat away on the phone or otherwise keep it at my desk while some special hardware emits energy through the air to charge my device(s), but I can't for the life of me figure out what the big deal is about putting my phone on a base—that's connected to the wall(!)—to charge my phone in a manner that's less efficient than hooking it up to our 3.0 cable (which, I might add, charges my phone from the red to full in about a half hour). After all, to even take advantage of this charging method we have to buy a special battery, equipment, and even a new case that's compatible with the charger. I just don't get the value...
So, I defer to the community to enlighten me--what do you think of the setup and what benefits do you see form your investment? Also, do you notice a difference in battery performance compared to the stock battery?
Thanks,
R
Wireless charging is not worth it. IMHO.
the best i seen wireless charging is 0.8-1.0 amps which is nowhere near the 2 amps that is more or less required to charge at a fast rate in a decent amount of time from 0 to full.
Yes, it is not as fast as plugging it in but it is great for the purpose of convenience. Just drop it on the charger when you are not looking at your phone... just one downside: the charging back makes the phone thicker and you cannot use most of the cases. If you dont mind a naked phone, go for it.

reasonable question if you drop that on the pad and just leave and not go back what would it matter if it was plugging and and left? then you'll come back to a more of a charged phone lol
i use my phone all the time. to have a wireless charger is pointless to me since i cannot use it while its charging, its worthless. using the wired method not only lets me charge but also use my device as needed. its 100% crap if you ask me.... unless you're the type of person that doesnt use their device all the time and can be away from it for 3 hours +
I have the (Fast Charging)CHOE Qi Wireless Charger Kit. Didn't have to change any of my OEM. It is slower than the cord but I usually charge overnight anyway. I like grabbing it right out of bed and going. It's 50/50 for me. Probably didn't need it but now that I have it, it's cool. I got it off Amazon so it wasn't that expensive.

Plugged is the way to go.
Until they come out with a wireless method like you stated (without leaving it on the charger) then I will just stick with the wire.
is it worth it to buy official equipment for wireless charging? no
is it worth it if you buy after market? yes! less than $25 bucks and you can have a wireless charger. yes it won't charge as fast as a plugged in charger but if you are charging overnight and want to protect your usb ports, check emails thru the night (i do it for business), and don't necessarily like wires on the side of your bed, i can't see a reason not to.

Easier way to charge at my desk or night stand maybe I don't wanna bend down and grab the wire then plug it in, call me lazy but I like it.

The benefit is 2 fold for me:
1) Ease. I have a Panasonic base that adjusts it's coil to line up with the phone so at night I just drop my phone on the base and KNOW that it's charging. Better than fumbling with a cable in the dark.
2) Less physical wear on the micro USB connector.
While not a wireless charger, the Amazon 9w speed charger & the Samsung USB 3.0 wire charge my phone super fast.
Wireless Charging
I did it just for the novelty factor initially. It was a good thrill, DIY mod types.
But later, I realized it is actually useful for me. I usually walk around while talking, and with Wired charger, I had to plug/unplug again and again after every call. Also, many times after unplugging, the wire slides down, and I actually have to crouch below my desk to recover it (call me sloppy, hehe). With Wireless charging, I just talk, place it back on the pad, nothing to worry about. It keeps charging while I do my work, and I also save the port (I've had port failing problems with other phones before).

No, just the same old-fashioned way
I never understood wireless charging. Usually I'm using my phone while it charges(can't do that if the phone has to be laying flat on a charging pad)...... Unless I'm asleep, wireless charging is a gimmick to me.
Since it's made of metal it is harder to create a wireless charging base for it.
The spec sheet doesn't mention it and it didn't happen on the M7. If it was possible they'd mention it most likely.
Also wireless charging is a godsend. I have the Nexus 4 Wireless Charging Orb with my Nexus 5 and it's so much better to just drop it on the ord then to fumble with a cable and everything. Definitely great when you're mad tired, drunk, or just need a quick charge while you're at home for a couple minutes.
Wireless charge is awesome, nexus 4, 5, LG, sgs 3,4,5 can do it, only HTC cannot.
I'd never use it since it takes so much longer to charge a phone.

Wireless charging is particularly awesome in my car. I have a Qi Car dock. Just slide my phone in and it's charging. I can play music over bluetooth, so literally no wires. I think I can't get the M8 simply because it's missing this feature.

Me too. I'm just not willing to throw away my investments in Qi, especially when I think it's great. I guess that leaves me with an LG G2 (Verizon one has Qi). Hate the build quality of the G2 though. I'd get an S5 (you can add Qi to it since you can take the battery cover off), but I hate the center physical home button.

From what I can tell my DNA does not charge slower and I think it is actually faster. Walk in and drop it on the charger as I walk by in the living room or on the one next to the bed. It would of been a nice if the M8 had that capability.

The answer is governed by Ohm's Law
Current draw is regulated by the device not the power source. Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points.
If you think about mains electricity, you can plug in a high current device like a kettle or heater to the same socket you plug in a low current device such as a phone PSU.
HTH.
I'd love to find a qi-enabled battery pack like this that has embedded magnets, so I can just stick my Nexus 5 to it, and put it in my pocket. True charging on the go.

The Qi 1.2 standard should be out about years end. It will support multiple devices simultaneously and can charge at a distance of about 2 inches. Backwards compatible will charge at a distance of about 30mm ish but still multiple devices.
