[Q] AT&T Note 4 support qi charging?

Hey all,
For those who got their Note 4 early from AT&T did they pull a fast one like the LG G3 and rip out qi charging pins in favor for powermat?
Thanks!

My understanding of qi with the note4 was that it only was available with the optional case, and it's not built into the phone.
Wasn't built into the s5 either.

Can someone with an att note 4 pop in a qi receiver and see if it charge up? I have a bad feeling they went pma just like the g3.

It's Qi charger. I don't have the adapter yet, but others have pointed out that the contact points on the back match the Qi specifications. I just got my Note 4, and opened the back, and indeed the contacts are identical to my wife's S4

Just because it has the Wireless charging contact pickups, doesn't necessarily mean it will work with Qi. The LG g3 had the same contact pickups, but at&t disabled Qi charging at the hardware level, and made those contacts only work with pma charging receivers.

let say wireless charging works, will it still take advantage of the fast charging feature though?coz I don't think so

NO, wireless charging is a Lot Slower charging than with your USB cable and AC adapter for Fast Charge.

It supports Qi. I bought the official samsung back. I use it with a Qi charger I bought off amazon. Works great but due to bulk, limits my cases.

Wireless charging can be done if you buy a wireless charging battery cover and these have them built in also. A cheaper route is just buying these little wireless recievers and stick them in, you can get them cheaper on ebay (but my work computer can't access Ebay sites).
Wireless charging IS slower than normal charging, its all about convenience. I have a few around the the house and a couple at work. Most output .5 - 1 amp range compared to 2+ amp chargers and the included adaptive fast chargers.
The links are for example only, not telling anyone to buy anything. Hope this helps.

Wireless Charging Issues

Has anyone experienced issues charging their GS6 Edge+ with Samsung's Wireless Charger (EP-PG9201)? I own two of these and used them with my GS6 Edge (non-+) without issue. Picked up the Edge+ yesterday and charging is erratic on both pads. I see that other users have reported similar problems (see below for links), but none of the comments proffer answers that I find acceptable. I am most interested in hearing whether you think this might actually be a hardware issue that is effecting some of the new devices (but not all) and whether I should therefore replace my phone while still within my 15 day window with T-Mobile. Responses from those with both the Edge+ and the Samsung Wireless Pad noted above would be greatly appreciated. I will also note that some users have experienced problems with the phone not recognizing the OEM Fast Charger (I do not presently have this issue) and am thinking that perhaps that the fast charger problem and the wireless charging issue might be somehow related (e.g., perhaps there is something wrong with the power circuitry on these devices). See below for more details on the wireless charging issue.
In short, more often than not, the phone simply doesn't charge. It connects to the charger for anywhere from 15 seconds to 5 minutes, then disconnects and the Samsung Wireless Charger blinks blue which is code for "hey buddy I'm not charging there is something wrong". Per other XDA forums, this problem also appears to be creeping up with the Note 5 (see: http://forum.xda-developers.com/note5/help/wireless-charging-issues-t3185669/page2
The most notable rumor/response is that the older charges simply aren't compatible with the Edge+, and that we are all supposed to wait until the new Samsung charger (see: http://www.samsung.com/us/mobile/cell-phones-accessories/EP-PN920TBEGUS) becomes available. A lot of people who took advantage of the Best Buy free Samsung charger deal (which came with the older model pad that I have) are now getting told by both Samsung and Best Buy that the deal included the wrong charger and they have to wait for the new one. I have trouble swallowing this as an acceptable response because the phone is supposed to support both Qi and PMA wireless charging STANDARDS out of the box, and therefore compatibility shouldn't be dependent upon using a particular generation of wireless chargers so long as they support those standards. From what I can tell, the new version of the Samsung pad is notably different in only one regard -- it sports faster conductive charging so they are adding "Fast Charge" to the device branding.
A YouTube user captures the problem in a video (see: https://www.youtube.com/watch?v=SfiGk6C3Yso), and the video comments note that the problem is not just limited to the Samsung charging pads. Other users who commented on this video claim to have contacted Samsung and were also given the "incompatible charger" response.

I believe it is the charger and not the phone. I use a cheap lukalake wireless charger and no problems at all with it. I did put my phone on the Samsung wireless charger at the tmobile store and didn't see any problems with that one either but I wasn't able to keep it on the charger for 15min which is when the problem starts to happen as people have stated here

Itan charger here with no issues when placed just right on the charger. I have ordered a different Itan charger that has three coils so that placement should be easier.

That thread is speculative as well and just confirms that something is awry.

Inclined to agree that yes, perhaps it's just a terrible charger, but it worked flawlessly with the GS6 Edge. Obviously the + has different coil locations given its size and perhaps the old Sammy pad just struggles with it. A shame because I invested in two of them.

I had posted in similar thread about this. I have an edge plus and bought the wireless charger same day. I spent 2 days with the blinking blue light. I called Samsung. Tech support told me they could send me a new charger. I told them it was a fairly widespread problem and I do not think that was the correct action. I asked for a supervisor and after a few minutes she told me the plus is not compatible with the current wireless charger. For the plus you need the soon to be released adaptive/fast charger. If you look at the wireless charger box, just about every new phone is listed as being compatible EXCEPT the edge plus. I returned mine and am waiting for the adaptive to be released

I have the newest fast charging samsung pad and I am having the same issues. I have to remove my case and it usually takes 3 attempts to place the phone correctly before it will charge When I use a cheap 9.00 charging pad it works instantly and charges fully no issues..I think the problem is the samsung charging pads.

Will the fast charging pad work with the Samsung thin plastic bumper case made for this device?

I just ordered one of these which hasn't arrived yet. I'm just wondering why that if my Galaxy S6 came with an adaptive fast charger for the house, then why don't they have the wireless charging pad version?

Who has tried wireless charging, and is it still working?

There are numerous threads on people's experience with wireless charging, mostly involving the stickers to use, meltdowns with heat, etc. I would like to compile people's experiences.
If you do have experience, please comment on:
1. Did you ever get it to work to your satisfaction? If not, what was not satisfactory about it?
2. How long did it last? Or how long have you had it working?
3. What qi charger do/did you use?
4. If it broke down, what happened and did you ever get it working again?
5. What model of G4 and/or carrier do you have?
Also, there's a quick poll associated in this thread.

This one, it was basically the cheapest one I could find June 2014. Once the phone is charged you can see the light cycle on and off just maintaining 100%. Works fine for a bunch of devices and I don't notice if it's slow as it has 8 hours to charge when I sleep.
CHOE UPGRADED Qi Wireless Charger Charging Pad https://www.amazon.com/dp/B00DRBFMZM/ref=cm_sw_r_other_awd_WNViwbW7EJTDK

I purchased this plastic replacement back that came with a qi sticker. I used it mainly with this CHOE 3 coil charger, but also tried it on this Yootech one, and this one as well. On all three chargers, the phone got super hot while charging. So much so that at one point my phone even froze up and I had to pull the battery. It may have been the qi sticker that came with the back I bought, but I stopped wireless charging after about a week, because I just didn't like how hot it got.
I'm thinking of picking up another qi sticker, but just can't decide which one is the best.

I'm using the official LG qi charger and the quickcircle cover with qi built in. All working but i find plugging in faster so basically just end up using that instead..

I've found that exact placement on the charger can affect the charging temperature dramatically. I think if the sticker is a little ways off from the center of the qi charger (wherever that is, not sure how that is determined on the 3 coil), it heats up a lot more.

Yeah I tried my best to make sure it was right in the center, but it seems no matter where I placed it it would get hot. Plus what's the benefit of having a 3 coil charger if I have to place it in exactly the right spot? I think there is definitely something wrong with the qi sticker I'm using. If not, many others would be having similar issues. I'm using fairly widely used chargers.

I never felt comfortable using the Qi charging after hearing the noise my phone made when I set it on the charger. I have multiple brands of chargers and all produce the same noise from the phone's speakers (youtube link below). I've tried with cases and without cases on all my chargers.
Here are my qi chargers:
1. Itian Qi Standard Wireless Charger
2. Axiong Qi Wireless 3-Coils Stand Charging Pad Stand Dock Wireless Charger for Qi Phones
3. Tmvel T2 Wireless Charger Charging Mount Cradle Stand for all Qi Phones, with Wide Charging Area for LG G3, Nexus 5, Nexus 4,Nokia Lumia 920, MOTO Dro

So an impressive 50% of folks on the poll at this time have had it crap out.
Wonder if the V10 will have this issue too? I'd consider switching to that, but the G4 is big enough already for me.

1. Works as expected
2. Have it for a week now
3. PowerBot
4. n/a
I'm using the official LG G4 CFR-100 cover btw...

After reading about wireless charging, maybe it's the reason why the feature was removed from phones released in my country. We got a dual sim variant where wireless charging was removed totally.

Wireless charging was removed from dual sims because the circuitry for wireless charging is replaced by that of the second sim.

1. Yes, it worked perfectly.
2. I only use the wireless charger at work and I started noticing issues after the 12th work day. Today is the 13th day and it is no longer working at all. When I power off the device and stick it on the charger, the charging light briefly indicates it's charging and powers the device on and then goes back to the idle state.

The T-Mobile store can put in for a warranty exchange, if you initially bought it with them. But then you get a refurb. It's $20. Alternatively, you could send it in for a factory warranty, but it'll be out for several weeks. And then after you get it back, the wireless charging will break down after a week or two. Ridiculous, right?
I think it's endemic with our H811 model. I wish this could be as big as Antennaegate, forcing LG to admit their poor design+engineering, but there aren't enough users to raise a stir.

I just had an online chat session with LG Support and since they only officially brand their Qi case for Verizon phones they are telling me that the T-Mobile model is not compatible with wireless charging and there's nothing they can do. I got this phone off CL so going to T-Mobile is going to be difficult. I purchased the LG G4 back on release day day but returned it so I was going to use that receipt with LG Support but it looks like that's a dead end.
Another question you should ask in this thread is which model people are using since this is a general G4 forum and not carrier specific. It does look like this happens with Verizon phones too though: http://forum.xda-developers.com/verizon-g4/help/wireless-charging-stopped-t3226231
Thankfully the battery life is good enough on this phone where I can probably live without the wireless charging at work. To be honest It was more of a must have when I had the S6 since there was no way I could make it through the workday without leaving it on the charger.

Wow, really? The function that works (at least initially) because all the hardware is there, on T-Mob, is "not supported?" That sounds like LG support has their heads up their butts, just like the QA department on the wifi charging.
I'll add the question of what version G4 do you have on the questionnaire. Can't edit the poll anymore though I wish I could.

1. Locked up during the night, multiple times a week.
2. Randomly started working perfectly for 3 months. Replaced phone. Worked for about 1.5 months. Now stops charging and locks up during the night again.
3. Nokia puck + Samsung + several chinese ebay units
4. Absolutely no idea why it magically fixed itself and now magically broken.
5. Verizon G4

Yes, but not for more than a couple weeks at a time.
2. How long did it last? Or how long have you had it working?
About 2 weeks, sent in for RMA, came back not fixed, sent back, worked for a little over a week, stopped today.
3. What qi charger do/did you use?
LG Quick Circle case purchased from Verizon, 2 tylt vus, one samsung puck.
4. If it broke down, what happened and did you ever get it working again?
No idea what caused it to stop working -- today it stopped somewhere between work and home.
First time, mailing it in twice helped.

Verizon

So... how it is with the charging, exactly? -- USB-C and wireless charging question

I am wondering about charging options for G7 and ask about two particular which I am most interested about.
1. Immediately when I got it I thought "cool, let's charge it a bit, let it sip a bit of a power from USB-C from the desktop", however there came the surprise No.1 - G7 is not fast charging, my 6P is (6P charges in 1 hour and something), G7 reported over 3 hours to charge.
How to fast charge the G7 from USB-C? I have a capable HW for that and Nexus 6P works that way.
2. I saw some mentions here that G7 supports 10W if not even 15W wireless charging, is that info verified? I am planning on buying a wireless charger (one at home, one at work), but I would like to know if there is pretty much any reason to buy 10 or even 15W chargers.

1. The desktop usually doesn't support fast charging. You need a phone charger that supports fast charging. The one included in the box will charge the phone for 1 and a half hours. You can of course buy a new one.
2. Any wireless charger will work but it won't charge fast. I tried Samsung's fast wireless charger but it charged the phone slowly. I would say, just use a cable if you're on a hurry and maybe a wireless charger when you're not using your phone.

But the thing is, Nexus 6P can, it is even stating it is fast charging via the very same USB-C port and cable, so naturally I am wondering why G7 is not.
Right now, G7 is being charged from USB-C just as long (considering what the estimation at the bottom of the screens is) I reckon would be charged via 5W wireless charger. I have dismissed the idea of more powerful charger, I don't need it, for that I don't mind it would be charging even over 3 hours.

And here's an example of how even though its a USB C port on the phone, not all features are implemented equally. Its either looking for some sort of resistance on the line in the cable or something else similar to that, as my Anker cables won't fast charge the G7 but will fast charge my Moto Z Play on my computer (which has the right port specs to support fast charge). If you look at the supplied cable with the G7, you'll notice that only one side of the C connector has contacts, and even then its a small amount of contacts that don't cover the whole side. more than likely the USB C cable you are using is fully built out so the phone is probably deciding that it won't quick charge when a fully spec'd C cable is used.
that's just my speculation

Nexus 6P doesn't support Qualcomm QC at all. LG G7 does.
Nexus 6P uses Quick Charge based on USB-C technology.
Different phones, different technology, different story.

Because Samsung wireless chargers use their own proprietary standard but not industry Qi which G7 is supported. G7 needs Qi capable fast wireless charging pad to enable 15W mode

Seems like Nexus 6P is capable of USB-C Power Delivery standard and G7 somehow is not. That's sad since I was hoping to buy one Anker or Aukey USB-C PD capable brick to charge G7 as fast as in can.

As for fast wireless chargers somebody should open a thread in https://forum.xda-developers.com/lg-g7-thinq/accessories about choosing fast wireless chargers. Like this one which is stated as supporting LG V30 with Qi EPP

Wireless Charging with Nokia QI (working on Xiaomi Mix 2S) and Ikea Qi charging not working

I have the S20+ SM-G986B/DS and unforunately it doesnt do any wireless charging. Not on my charging pads and not in Volkswagen or Audi Official Charging areas. Tried to turn on and off the fast charge capability but it does nothing at all.
Looked for further help in the Developer Settings but nothing htere that could help. Should be on the newst offical version out there in Germany.
Is there a solutions to this problem?
It was just handed over to someone else to use it which is odd as it was just factory. I believe i used it last year at some point and it worked on the wirless charging pad "Fatboy" i have from the good old Nokia days. It is not in a case or anything

So am i the only one with this problem and a broken device or is it some software issues with Samsung

Okay, thank you. Very helpful

The only thing i think you can try is to use original samsung wireless charger, any will do. If it does not start charging, then i'm afraid its a problem with your device. The reason i'm suggesting this is that samsung included recognition of wireless charger at some point, and if its not made by samsung it wont start charging. That doesnt mean that it wont work with any other, but may be the reason that your device is not charging on nokia charger.

I have few cheap chinese QI chargers (home/work/cars) and they work perfectly fine with S20+.
They work fine for IPhone, S8 and S20 too.
