I bought a QI wireless charging adapter from Ebay and installed it in my s4. I used Nokia QI wireless charging pad. However, I found my the charging was intermittent after like 5min of continuous charging and that was when the Nokia pad & my s4 both got very warm.. The phenomenon was: the screen kept coming on every 5seconds like the phone was disconnected from the power source and reconncted.
I found that, when I put s4 off from the charging pad, let phone cool down, put it back, it would work flawlessly for 5min, again charging intermittently. This bothers me, as apparently the physical charging worked for my s4. Might be the wirless charging issue related to s4 firmware?
Any inputs are welcomed.

I've been using wireless charging at home and work for over a month and love it. But it stopped working a few days ago, and the device no longer detected when placed on a wireless charger. Then it worked sporadically for a day, and now it's dead again. Any suggestions or diagnostics I can run to figure out if it is a hardware or software issue? TIA
Sorry to ask ... but it could be the charger itself ?
I have a cheapo charger and it can act up sometimes. Luckily, it has a LED ... if the light stays on after I remove the phone then I
will need to reset the charger (or it won't charge the phone next time).
I don't think it is the chargers, since the phone started failing on both at the same time and the Nexus 7 still charges fine on the one I have at home. I wonder if there is a software setting to turn wireless charging on/off or something?
I think that the problem may have been static for some reason. I have found that rubbing the back of the phone with a cloth (my shirt) before putting it on the wireless charger gets it to work. This holds true with or without bumper case on the phone, and works for my home and office chargers. Strange.
Ok so I bought official charging backplate for my Note 4 and my wife's S5 along with two separate Samsung mini charging plates. Last night we installed the cases and place our phones on their own pad. Mine was in the living room and hers in the bedroom. My phone was at about 50% before I popped it on the charging pad. When I placed it on there I got the charging beep on the phone, green light on the pad and a little message that the phone was charging wirelessly. Same with my wife's phone. Woke up this morning and the battery percentage didn't move on either of our phones. My phone is still at 50%ish and she reported her phone didn't charge as well.
What gives? Any suggestions? Both our phone show charging when on the pads and the green light turns on which means it is charging correctly as per the instruction booklet.
Check the specs on that pad and see how much it outputs. I suspect it is not enough for these larger phones. It may just be enough that they don't lose charge. I use the TYLT Vu Wireless Charging pad and it charges up over night on my Note 4 very reliably.
you need a high power usb connection for charging pads and a good pad.
i have a choetech, itian and a few others which work well IF they are connected to a high power usb port otherwise they dont work. some of them will flash leds or the phone will say connect/disconnect continuously. they need to be connected to a usb wall wart or computer socket or car cig lighter port directly. a usb hub or old usb 1.0 port will not do. a low power charger will also not do but that is less likely. chances are youre not supplying it with enough power and/or not aligning correctly.
So last night I made sure that all apps were closed and that the phone was exactly centered on the pad. This morning it was at 100%. It's a 2a charger that came with the pad and since there is about 50% loss with these charger I'm assuming it charges around 1a once it hits the battery. Seems to work now. Thanks!
phone shouldnt be centered on the pad. the coils are offset by around 3/4-1 inch from the center so the phone will be a bit high (or low depending on how you place it). obviously if you have the 3 coil qi charging mat/rectangular plate instead of the 1 coil disks/plates then you can just throw it on in anywhere and it will charge.
Hi, I have an S6 Edge+, 64GB for around 2 weeks now, and I bought a wireless Charging pad that supports fast charging (Samsung Pad).
The problem I have is this:
1. When connecting using the Charging unit that came with the S6 Edge+, it charges my phone wirelessly in fast charging mode.
2. What happens when I pick up my phone, then in a minute, put it back in the pad, it doesn't recognize my phone. the only way it does again is by restarting my phone and removing the fast charger transformer (whatever it is called) and replugging it again.
However:
- I have set in the settings -> accessories to fast wireless charging. if I don't set it, it's normally just wireless charging.
- When I use the charging unit from my Galaxy tab S2 (non-fast charging unit), the pad works seamlessly, but no fast wireless charging.
I don't know if it is a problem with my unit (my phone or charging unit), or is it a problem of my pad which I have until Saturday to return for factory defect.
Just for I know, where is those accessories settings?? I didn't find anything about that on my edge plus

I added a wireless charging receiver to my ZTE Axon 7 mini and I get an odd sputtering/stuttering/hiccuping happen at around 91% charge. Every minute or so the phone looses it's wireless charging connection, reconnects, then continues charging until the next hiccup. Eventually the phone will charge to 100% and the hiccuping then stops.
The problem does not occur when the battery is below about 91%. And I don't get this problem if I simply plug the phone in to charge.
The biggest annoyance for me is that I have it charging at my bedside while sleeping and the frequent charging beeps and screen turning on wakes me up. The solution I've found for now is to set my phone to Silent while I'm sleeping, but though that helps with the beeps I can still get woken up by the flashing screen. And of course, there are other issues I have with setting the phone to Silent.
I have wondered if this was the receiver or the charger at fault but I've tried one other receiver and 2 other chargers with the same result.
I do suspect this has something to do with what I assume is a slowing of the charging rate as the battery gets close to full but I don't know how to confirm that.
Any suggestions to resolve this greatly appreciated.

From what I can guess, the problem was a combination of placement of the phone on the charging pad and/or the presence of a metal disk (behind the receiving pad, though) for a magnetic car mount (though this was not an issue with wireless charging in the car via the mount) and/or the end-of-life of the wireless charger.
I found that placing the phone horizontally and in a specific position stopped the fluttering.
And interestingly, about 2 weeks after this post, the wireless charger gave up the ghost.
In the last couple days I started noticing the fast wireless charging is not turned on every time when I place the phone on all of my three fast charging pads. Instead the phone just shows the regular wireless charging status. If I lift the phone and put it down again, the fast charging will turn on randomly again with no observable pattern.
Does anyone have the same problem? I have wiped the cache,thinking it might have been one of the latest Sprint updates, but it didn't solve the problem.
I've had this issue too, how long before it's switching to slow charge? Mine does it if the temp gets too hot usually, but other times the wireless charge doesn't work at all. I think it might just be a bad pad though and not the phones fault...
Mine was doing about the same thing ...it would say wireless fast charge as soon as I set it on the pad and one second later it would say wireless charging. I switched the power brick from the one that came with the charging pad to the one that came with my s10 ( faulty brick maybe?)and that did the trick for me. For reference I'm using a Samsung wireless charging pad but that was my experience
