Qi Wireless Charging Kit turns on and off repeatedly

I bought a generic Qi wireless charging kit. It has a white receiver which you open up the back cover of the galaxy s4 and then fit the prongs in place. Then closed the back cover and put it on my charger pad. The charger pad is powered by my OEM Samsung 2A output adapter so that should be plenty of power. There are two lights, one red that is constantly on which I assume is the power light. The other light is green, but it flashes. I'm not sure if it is supposed to do this, but pretty sure it is not as my phone will display a popup notification that wireless charging is enabled. One second later, the popup is gone and the battery icon no longer shows the thunderbolt charging symbol. Another second later, the notification comes back and the battery icon shows the thunderbolt charging symbol. So both the charger pad flashes and my phone's notification and battery charger icon appear and disappear every few seconds repeatedly, anyone know what is going on?

Kind of hard to tell without seeing which one you specifically have. Got any links? Have you made a good connection with the contacts on the back of the phone? And are you placing the phone in a good spot on the charger? I have 2 qi receivers like yours and I don't have these problems unless I'm using the official nexus wireless charger. I think the magnets in it do something to offset it. I have another wireless charging pad and I don't have these problems at all.

I actually do have the link: http://www.ebay.ca/itm/181216698737...eName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I made sure to buy the GS4 i9500 and almost certain this is a right purchase as the prongs fit perfectly. Based on the instructions, the actual charger is under the symbol/icon, which I have tried to place perfectly. Heck, I tried so many spots with no success. I'm not sure if the receiver is faulty or if the charge pad is faulty. I'm looking into a ChoeTech and Incipio Qi charger right now as its around 30 bucks and have quite some positive reviews.

Well that thing is one of the thicker ones. And I've never liked the design of it. I'd definitely switch receivers. Then chargers if you problem still occurs.

1. check to make sure the contacts on the receiver are not getting disconnected inside the phone.
2. you need to find the sweet spot on your pad when you put your phone on it

Well, I'm in the process of getting a refund on eBay. Guess I'll have to go for a more branded charger instead of some no-name generic.

wireless charging going bad?

I've had a Nexus 5 since mid November 2013. Each night it is charged on a Tylt charger, during the day at my office I have the newer Nexus charger. Within the past month, the Tylt has been intermittently not charging (the green light on the bottom won't light). I could sometimes have success if the phone was turned sideways. But the nexus charger would usually do the trick. Recently the Nexus charger won't get the phone in wireless charging mode either, whether the phone is on or off.
Anyone had wireless charging go bad? Anything to try other than call Google and swap it out? Sean

If you have access to another Qi Wireless Charger try it on that, otherwise it could just be a problem with the coil even though that's unlikely. Did you pull off the back cover at any time?

It's not 100% clear but I believe when he says the Nexus charger he means the Google Qi charging unit, so he would've tested it on there and the Tylt.
Question: Have you ever removed the backplate? Or maybe dropped the phone? If so one of the clips securing the backplate might have loosened.
Try pushing down on the back of the phone right around where the X or S is andif you hear a click it should've snapped back into place. This is most common for people who have removed their backplate.

The clip that's typically the problem can by located thus:
Form a cross (two perpendicular lines), with one line running along the bottom of the letters in NEXUS on the back cover, and the other line coming from the flash. The clip is located where those two perpendicular lines meet. Press down there to ensure it's properly seated.
The entire purpose of that clip is to ensure that the wireless charging contacts seat correctly. If that clip is unseated or broken, you'll (eventually, if not immediately) have wireless charging issues.
However, it doesn't take much to damage the wireless charging system in the N5. My first unit stopped wirelessly charging after I dropped it from a height of about 2 feet (from a seated position), and it landed flat on its back on a tile floor. Luckily, if you bought it from Google, it's still under warranty, and wireless charging not working is a valid warranty issue. (Hence, why I said "my first unit.")

Best phone cord charger?

What's the best cord? my cat keeps chewing on mine and i need something strong + fast charging. and under $30

Ever considered a wireless charger? I have 3 cats myself and they leave the wireless charging pad's cord alone because it never moves.
I got sick of peeling open the water seal over the data port every time I wanted to charge the phone, so I bought the samsung charging cover, and got a QI charging pad off of amazon.
Even went as far as getting a QI car charger/phone holder for in my truck since I use the phone as a speedometer + use internet radio.
It's a small investment, but I'll never go back to charging with a cord again. QI is standardized, so any QI standard cover will work with any QI standard charging pad. doesn't matter what device. can be any phone or tablet or other device with a QI charger on board.

Cheap QI receivers experience?

Hi, I would like to ask you, what is your experience with that cheap S4 Qi receiver pads (for example from ebay...). Is it charging fast? How much is cover bulged? Is it dangerous for the battery?
Thank you very much for sharing your experience.

It does make the back cover bulge a bit but it's not bad.
The phone gets warm when charging wirelessly but it's not too bad at all.
Sometimes, the charging pad will detect the receiver but the phone doesn't charge. If I remove the phone from the charging pad for a few minutes and put it back, it will start to charge.
Charging wirelessly is not as fast as using a wired charger and I would say it takes about 30 to 50 percent longer.

Thank you for response. Is NFC working with that Qi pad?

I have never used nfc on my phone but I know you can get pads that do support nfc as an option.

Hi there
I have a qi receiver on the S4. My one has input: "self-adaptation" (whatever that means) and an output of 600mah. It charges at a decent speed. I use the LG G3 wireless charger and a few other wireless charging pads and they seem to charge at a decent speed. A full charge takes about 3 hours.
The cover does bulge a tiny bit, but it is barely noticeable trust me- definitely worth it.
The phone only gets a little warmer- again nothing to worry about for sure.
I am certain that it doesn't do any damage to the phone and battery. I have using wireless charging overnight everyday for the past few years on the S4 and nothing has gone wrong. I rarely use cable charging anymore
I recommend getting a qi receiver for the S4- it is worth it.

Has anyone found a Qi charging receiver so thin that it doesn't bulge at all?

Is it today something better what can more than 600 mA ?
Can you recommend something good ?

I can tell you the one from Aukey, although it uses a flat printed circuit coil, bulges a lot. Enough I didn't want to use it. It was advertised as being "ultra slim 0.2mm", but when I measured it with calipers, it's more like 0.9mm. The ferrite pad on it is most of the thickness.

No Bulge

The Fone Salesman S4 SlimPWRcard does not bulge at all.

Fast wireless qi back cover or pad... Does it exist for our phones?

Looking for a back cover OR a qi "pad" that fits inside the phone that ALSO takes advantage of fast charging qi. Not the standard rate of wireless charging. Thanks

I haven't seen anything but cheap stuff. Perhaps phone doesn't support fast charging via those contacts on the back. Also I don't see anyone developing such a thing for an outdated phone.

The Note 4 doesn't support Fast Charging on wireless charger. If you do put it on a Wireless Fast Charging pad, it will charge at normal speed. I actually tried this with a Samsung wireless Fast Charging pad and a Samsung Note 4 S-view case made for wireless charging. In order to use wireless charging on the Note 4, you have to have a case or battery cover that supports wireless charging. Or, you can get one of the wireless charging receivers available on Amazon, eBay or elsewhere. I haven't tried one of the receivers, though a friend did. He had mixed luck getting it to charge at regular speed. Apparently not all receivers are made accurately enough to touch the necessary contracts on the case and phone.

How does the combo Fast charge Samsung pad and S-View wireless combo work together? I mean, does it heat up the phone and how fast does it approximately charge? Thanks.

The one of the wireless chargers I use made the phone too hot for my liking. The other one seemed to work fine. Haven't tried the Samsun ones. I had a wireless charging pad initially on the back of my phone, but I popped the back off enough times and it always felt like it was bulging out a little, so gave the old s-view case to a friend, and bought the one where it was integrated. Works great. But yeah, I don't think it supports the fast charging.

I've using this: http://www.ebay.com/itm/301400816942?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT, for over a month. I'm using it with a "normal" samsung reciever, it works well, the phone doesn't get too hot, but the charging speed is far from fast charging, so, it is more like a gimmick.

It works well. Not fast, but it also doesn't heat up the phone. That's the reason I got it. I didn't really time it, but I would expect it to charge at the standard 1 Amp/hr. So, about 3-4 hours if the phone was totally dead. I got it because my phone was over-heating with the fast charger that came with it. I got my charger as an open box at my local Microcenter. However, Amazon has them for around $20-50, depending on if it's the Fast charger or the standard one. One thing I would look at carefully is whether the Samsung wireless chargers at Amazon are real OEM Samsung, or fake. The wireless S-view case I got came from Amazon. It was in Samsung retail packaging and sealed. It was around $31.50 and new. Fortunately I got it with Amazon Prime shipping for free shipping. I just checked, though, and the prices have gone up to over $40. There is one for $33-$34. Another possibility is buying the "battery charging system." It is basically a battery charging case, a new battery and a carrying case for your spare battery. I got it from Sprint for around $25 + tax. The shipping was free. You have to use your own charger with it. It seems less likely to overheat. It has been better for me to have the extra battery. I think I mentioned that I had gotten my Note 4 replaced under TEP, as it was over-heating. I think it was that particular phone that hated the first update to MM. OTOH, my replacement Note 4 has been very happy on PG1, which was on it when I got it. I usually make it through the day with a charge left on the battery I started with. I carry my spare in case. It hasn't overheated. I am hesitant to use Fast Charging, if I don't have to. I believe Fast Charging is more apt to overheat the phone and battery, and probably shorten the life of the battery, if not the phone as well.

are all the s-view cases supporting Qi charging? how can I tell if one does before I buy it? how many contact pins will it have?
thanks!

I use the following 3rd party Qi charging back, and although it is a tight fit, it seems to work well and says it supports 650ma output via the charging pins. It also says that it supports s-view function, but I don't have a s-view case to test with.
Again it is a tight fit, but if you put it on from the bottom first, it can be massaged on.
