Poor Wireless Charging with DT-900

I've seen several threads on here about the wireless charging "re-cycling" (flipping between charging, then not charging) of the DT-900 with the N4. The solutions I've seen on here don't seem to be working for me as I'm not 100% certain that is what's going on. Here's my situation:
N4, white one, so it's a new rev. Older revs of the N4 reported issues with this charger, but supposedly it was fixed with the newer revs.
CM 10.1
Stock kernal
Tried with a case, and without.
Daydream enabled/disabled
Completely flat surface. phone is not moving at all
So...I put the phone on the charger, positioned so the bottom of the charger extends a little less than 1/4 of an inch from the bottom of the phone (I've tried different positions on the charger with no change in results. From what I've read, this seems to be the sweet-spot for this combo.) The phone indicates that it's charging, flickers between charging and not charging 2 or 3 times, which from what I've read, is a positive reaction. Then, the charging light stays on from there. The battery screen reports "Charging Wireless" but it really is not charging. The battery does not seem to drain at all, but it does not charge. It just kinda hangs right at the 70% it was at when I dropped it on the charger. I left it there overnight a few times changing one thing at a time (case/no case, phone position, daydream on/off, etc.) and each morning, the battery would pretty much be at he same level it was at when I wen to bed.
Any ideas/recommendations?
Thanks!

Just got one of these for myself and I'm seeing exactly the same results you are. Says it's charging but it doesn't battery level has dropped at times while on it. I have had it on the charger with and without a case and no change. Hope somebody knows a trick cause i'm gonna feel dumb having wasted 50 bucks. I'm also on CM10.1, stock kernal.

I felt dumb wasting 50 bucks on it too. So I took it back to the AT&T store I got it from. If you can return it, do it. Then go straight to a Verizon store and get the LG wcp-300. I think that's the model number. 10 dollars cheaper, works way better.
Edit: Here is a thread on it.

The only one it struggled with was my seidio convert case. It worked, but it charged slower than with any other case on it.

Well, I guess it's an issue with that charger then. Oh well, I got it for $25 so I can't complain too much I guess.
I'll look unto any recommendation here and see where I end up.

That's the one I ordered, except it was from a US seller. I use a Seidio active case so I will let you know how well it works with that case, the Nokia one did not work well with a case.

I received the Qi wirelesss charger today and it does work, but not with a case. I have a Seidio active case and tried it with it on and nothing, then tried it with just the silicon back and the charger activated but did not charge the phone. Same results as the Nokia charger, but it was half the price. I have the official bumper case and will see if it works with that.

I've been using the Koolpad (have one at home and at work):

Works pretty well. I disabled the sound- found an old thread on here that showed how to do it. Pretty simple to do.

As far as the dual standing desktop charger goes, do we know if this will work with the factory receiver backing plate? The Tylt View does not because the receiver on the phone is in the wrong place for it.

This is the same with my sanwa/maxell standing charger base, although it does have 7 coils, the samsung wireless back does not work the normal way, you have to place the phone upside down or horizontally.

I agree, the powerqi T200 is a decent charger, the coils and PCB is good quality and does have a good detection with most phones, but I prefer the metrans MWT 03S, much smaller and very good detection, but only available in black with aluminum frame, I would like to see a whte version.
MWT 03 all plastic
MWT 03S with aluminum frame.
I highly recommend these, although they are single coil, they detect the phone pretty well and charge pretty cool, with good style, the LED is not so bright and they are made in korean.
Now i'm using the Araree/powerholic different names in different market, the uneven surface allows the phone to charge cooler.
The edge of the center part has a rubber ring to prevent the phone from slipping or moving around.

I got a wireless charger and receiver on ebay it is round and slanted so I use it almost like a dock
the issue is the phone keeps turning on and gives me the BAttery fully charged notification.. is there a way to stop that notification?
also the wireless charging notification comes on as a box and while that is on I can not do anything on the phone and have to wait 5seconds for it to go away .. it would be nice if the wireless charging notification could be much less intrusive..
P.s. my charger charges the phone at 620ma which is better than my 10ft long usb charger at 300ma and worst than my wall charger at 1200ma.

Has anyone managed to try a few of these out? Any comments on which works the best?

Personally after having 4 different 3rd party chargers I've stuck to the Samsung ones. They just seem less fussy about placement. They also don't have annoyingly bright LEDs. Over here they are £25 on Amazon. Worth paying the extra £10 or so over the cheaper ones.

Do any of these 3rd party chargers work with the Samsung s view wireless case?

Portable Wireless Charger Power Bank 4000 mAh
I was wondering if anyone has tried the Qi-infinity™ Portable Wireless Charger Power Bank 4000 mAh on Amazon. Unfortunately, I cannot link it because I haven't posted a lot on XDA.
It has great reviews from verified purchasers but I'm still skeptic. I'll place an order for it tomorrow morning if no one has tried it and update when I've used it.

Thank you, sir!

May I ask if anyone knows which QI charging pad is compatible?

Samsung is releasing their own Qi charging pad/station pretty soon. I personally use the one from TYLT. It's been great with my Nexus 7 and my friend's Nexus 5.

I believe any QI standard charging pad is compatible.

^^^ correct

Well, when the Note 2 first came out I tried two different QI charging pads that were supposed to be compatible. While one worked partially and was impractical as it would connect/charge for a few seconds and disconnect randomly, the other would not work at all. Perhaps I'll wait for the Samsung one as I am sure that will be reliable.

Has anyone seen the measurements on the wireless backing. I have a few cases pre-ordered and hope they will work with the official back. On the Note 3 I had to get rid of the official wireless back and replace it with the Tylt wireless pad and the original back.

This is a good news.

Back cover
Thanks for the info

I just got my Note 4 today.
The wireless charging pins on the back look very close to the same as the S5.
I have a QI receiver for my S5 that I am going to try when I get home and see if it works with the Note 4.
Anyone else want to test it out in the mean time.

Very interested if the S5 one works so I can order some QI Battery Receivers if so

My local Verizon store had the wireless charge S-view cover for $50, a hell of lot easier on the wallet with the link posted to Expansys. Appreciate it !!

MY guess is that it won't fit most cases, so keep us updated.

Without a doubt the official Qi back will be at least 1.5mm thicker than the non Qi back making it incompatible with nearly all cases. The way to go is by just dropping a Qi receiver behind the original cover.

Spridell,
Any luck getting the QI receiver from your S5 to work with your new note 4? I'm hoping it does work so I can get one ordered for my Note 4 shortly after it arrives. I've been using one with my S4 for the past year plus and definitely don't want to add to the thickness of the Note by using the Samsung QI back cover.
Thanks!

Thanks for letting us know. I was able to find this side by side of the Samsung Charging Cover. If you look in the picture, it appears that the backs are not snapped on all the way, so keep that in mind. It does appear to be at least 1mm thicker.

Nothing held it in place perfectly like this did. Literally half a mm shift and it doesn't make contact. It has to be exactly precise.
This way it's really locked into place and ive used it on 3 different chargers and it's been perfect

Bought the same setup as you and i am experiencing an issue with thr charger...if i set the phone on the charger in landscape in the vertical slanted position it will charge for a while but then stop and i can hear a clicking that comes from the charger. Sometimes the charger will even cycle from charging to not and the blue light on bottom starts blinking.

I did this on my S4 with a hot glue gun by placing the receiver on the phone itself, put a few small dabs of hot glue on the wireless receiver then put on the back cover. Now when you remove your back cover the receiver will be attached in the perfect location.

That's an excellent idea and I thought of doing that but didn't have a hot glue gun. That would definitely be very accurate

Does it deform the oem back cover? I have the cheapo ebay receiver and the phone won't sit flat.

Wireless charging & cases

My wife and I both got an S6 (mine is Verizon and hers is Sprint through our companies). I bought the Samsung charging pucks off Amazon Warehouse Deals and they came from China so I do not know if that has anything to do with my problem.
First, the phones would charge then pause then charge then pause over and over again. I corrected this issue by connecting each charger to its own dedicated power (I was using this and its apparently 2.1A combined: http://www.monoprice.com/Product?c_id=109&cp_id=10907&cs_id=1090701&p_id=9195&seq=1&format=2). So now we can charge but the location is extremely fickle.
Second, now that we are charging, if I use anything but an ultra slim case, it does not work. I have the Ringke Slim and have her using a cheap hybrid case from Best Buy. I have several other cases but they do not work (Speck Mightyshell, Rinke Max, etc...)
My question is several really.
- This is my first experience with wireless charging, do other wireless chargers perform better or is this par for the course?
- Is the fact that these came direct from China an issue? Maybe a newer version of the puck works better?
- Has anyone else had solid experience charging with a larger case? Mainly the Speck Mightyshell because my wife loves it.
Thank you for all your help XDA community!

That's the sign of a weak charging coil. I've used the Samsung puck (ECP-920), several Nokia chargers (DT-910, DT-920, DT-601, DC-50), and the Panasonic Qi pad. . I've used the Casemate Tough, the Ballistic Jewel, and several Spigen cases, which vary in thickness between 1mm-4mm, and never had issues with any of the above chargers save the DC-50, which behaved exactly as you described. The rest stay charging without constantly disconnecting and reconnecting to the phone, which also causes it to heat up.
In your shoes, I'd spend the extra $10 to get better chargers - there's $20 chargers on Amazon which have good reviews and seem to work properly. Heck, the old Nokia DT-900 works great, I'm told, and since it's discontinued sells fairly cheap as well.
I've already returned the DC50 for another Samsung puck, which was on sale for $30 or so at the time. I wouldn't advise keeping those cheap chargers, since they'll behave similarly badly with most Qi devices.

Thank you for the reply. Just to note, they are genuine "Samsung" pucks. They may be fake but were purchased off of Amazon. I will look into this.
Is this an unequivocal "best" charging pad?

I've had similar problems with the starting and stopping of charging. Usually, though, it's due to not being on the right spot, exactly. I can usually get a sweet spot and it will stay a lot better. I also noticed more problems with it when I had a slicker case on the phone, and I think it would shift a bit on the puck when people would walk around the house.
Also, as I mentioned, I had no trouble charging through a case. My wife briefly had some case from Best Buy before switching to an Otter Box Commuter, and I had a Spigen Ultra Hybrid before switching to a Verus Iron Bumper. None have had any trouble with the Samsung charger.
I will also throw out that I am just now getting my first experience with a different wireless charger, having bought a "Freedy" one from Amazon to put on my desk at work. It seems fairly decent thus far, though I did notice yesterday that it seemed to get really warm when I left it on there for a long time (not an issue with the Samsung charger). I am going to monitor that more over the next few days.

I wouldn't call the Samsung one the absolute best, but it works well for me. You have the square ones (EP-PG900) or the round ones (EP-PG920)? I've the latter, which I bought in store. You may want to RMA them if they're the round ones and won't charge the phone even when the Galaxy logo is on the coil (the area inside the rubber circle) . The PG900s have been causing issues with some folks, from what I've read here and in Amazon.
Beyond that, I'd suggest getting a reputable brand for the charger - the Aukey one gets good reviews, for example. I've got quite a few Nokia chargers, and they've not let me down yet... except the DC50 wireless battery pack.

Just because they have Samsung printed on them doesn't make them OEM. I see 10$ pucks on eBay that have Samsung print on them. They come from China and I would bet money they never seen an actual Samsung manufacturing plant

Here are some pictures. Maybe it's a really good fake. I will take it up with Amazon if so. I've purchased another CHOE Qi Stadium charger to test.

That might be a fake. Did you get it from Amazon or a reseller using the Marketplace? The Yamsung thing is one I've never seen, and the Qi logo is in the wrong place and drawn incorrectly. Also, scan the QR code to see if it takes you to Samsung's site.

I did. I am not at home but I scanned the QR code from the photo and it has some japanese jibberish. If the one I ordered works better, I will return these and update this thread. Hopefully this helps someone.

My QR code reader couldn't read the code off the image you uploaded, and on my pad the code's actually just the serial number and model number, not the URL I had remembered.
If you didn't see a "sold by Amazon" link on the purchase you made, I'd say you got a fake.
