qi charging working strangely - G3 Accessories

I recently purchased one of the qi/nfc charging stickers from Amazon and installed it myself. The nfc works perfectly and the qi charging indicates that it's connecting to the charging station. The problem is not only does the phone not actually charge the battery, it seems to cause the battery to discharge at a faster rate than normal.
Example: Battery is at 78% charge. If I leave the phone just sitting on my desk in a half hour it will lose 1% and be at 77%. If I put it on the qi charger, I've tried two different charging pads both of which charge my qi enabled S4 just fine, after the same half hour it will have dropped 4%. So somehow being on the qi charger is making the battery lose power faster than if I just left it sitting on my desk.
I've run this experiment several times to make sure it's not some errant process in the background. I've looked at the contact plates on the qi sticker and they had pressure indents from the where phones charging pins are making contact. I imagine that indicates the pad is making good contact with the sticker so I'm not sure what else could be going on here.

My first thought is the contacts may be reversed. Since you don't give any information on your phone it is hard to say. The phone I purchased (855) had QI as part of the back as does the Quick circle case I bought for it, and both work quite well with all 4 QI chargers I have. You also have not given any information on the "sticker", where you bought it , who makes it, what the model is, how you installed it.....
Not really any way anyone can help with this except to say try a charging back from LG for this phone. Frequently the problems and stress incurred from buying aftermarket phone parts outweighs the cost of the OEM part.

Qi Car Charger

Has anyone purchased/used one yet? I am looking at getting one, but haven't yet, mostly because I haven't found one that I am sold on. Thanks
I've got two different ones that I've tried now and neither of them keep the phone charging, but the battery will usually stay at the same amount. They charged my Nexus 5 pretty well even under hard use while driving.

I'm having the same issue. Which chargers did you try? Mine is this one
Weird, because my Tylt Vu works just fine with it.
Also interested in seeing what people are finding useful.
I'm looking to buy one soon, and this is the one I have my eyes on now. http://www.amazon.com/CHOETECH-Wireless-Charging-Blackberry-included/dp/B00JA7HNZO

Funny enough, one of them is the same one you just posted, just a different brand name. Worked good for my Nexus 5, but my LG G3 usually just stays at the current level when I put it on there with Ingress or Waze plus BT Streaming going on. If it is hot out it loses charge slowly.
Here's the other one.

Grips MUCH better, and is a really nice mount. 3 coil also, but not enough juice to do better than the other one. I've tried multiple 2.1A usb chargers too.

Good to know. I almost bought the one you have hoping it would solve my issue. Back to the drawing board I suppose.

Does your DigiYes consistently charge your phone? I have one of the DigiYes models, but I'm finding it frequently stops charging, often within seconds of beginning charging, though sometimes it lasts a few minutes before giving up. I always get the "Wireless Charging" message on the display, never the "slow charging" warning.
I tried swapping their 2.1A cigarette lighter adapter for an Anker 2.4A charger -- same deal. Tried adjusting the vertical position in the charger -- sometimes seems to last a little longer before giving up, but generally doesn't help at all. When it stops charging, the blue light stays on (rather than going back to green).
When it does charge, I seem to get a decent charge current out of it. Very confusing, and probably going to get shipped back.
Edit: it seems to drop out less when charging from wall power, though it still happens -- perhaps correlated with greater power demands on the phone (Google Earth).
I did state above that it charges my phone, but if Navigation and BT Streaming is going on it keeps it at a steady level, or if hot discharges slowly.
If you don't have a 3 coil QI charger, positioning is very important, if it charges and stops, it is a positioning issue for sure.
Changing to a higher amperage charger won't help, as Qi only puts out so much. The new Qi standard coming out should fix this for us though, it transmits 2 amps I think, and has more distance so positioning shouldn't matter AS much.

Does the DigiYes disconnect constantly like the one I have? Or no?
Nope.
My other one did, but after adjusting how high it sat with the bottom brace that problem went away.
My air dock keeps the phone at a steady charge while running navigstion, bluetooth (aptx) via stock music app, and 100% brightness. The thermal protection activates eventually and lowers the brightness to 90%, and then it starts to very slowly charge. It charges fast if not running anything.
Also, you don't need 3 charging coils. My powerbot disk style charger easily works without worrying about position. I opened it up and the whole thing (~2.5") is one big coil. The air dock works well too, but I haven't opened it up.

I have two air docks (from the original crowd funding campaign) and neither one of them will hold my G3 (with the included magnets used). How well is your sticking? I wonder if I got an early batch that didn't stick well?

It works perfectly fine. Does yours use both magnets and the suction pad? I believe they were separate options in one development point. Also, my car was dusty and it did get some dust on the pad which made it not hold, but wiping it with a damp cloth and letting it dry fixed that issue.

My DigiYes 3 coil frequently disconnects, sometimes in a constant connect-disconnect loop. Other times it holds for a while. It seemed to do better when I put it on a higher amperage charger than it came with, along with the original G3 cable. However this could be coincidence. When it does charge, the charging rate is comparable to any of my desktop qi chargers.

[Q] Charging speed / wireless chargers?

Hello everybody!
I've got two questions:
Since I'll be receiving my direly awaited S6 Edge 64gb tomorrow, I have two questions which I couldn't really get any good answers for.
The first one is about the speed of charging. Since the battery in the S6E can't be switched so easy, I'm a bit concerned about battery health, especially since I plan on using the phone for a long time (budget is tight). Now with my last phone (which unfortunately I had to sell in order to come up with the money for the S6E) I used one of my computers USB ports to charge the phone over night. I read somewhere, that it's better for the battery to be charged slowly and since my computer powers the front USB even when switched off, I always used it to slowly charge the phone overnight. It would be faster charging with a wall outlet, but I didnt need it to, so I figured it would be beneficial for the health of the battery.
Is that actually true? Is there maybe even some way to keep the phone from charging higher than 80%?
My second question is about wireless charging. I'd really like to get a wireless charger for my desk at work, however I will be using this ->
*cant post the link, it's the "Galaxy S6 Edge Case, Spigen [CURVED BUMPER] Neo Hybrid Series Case for Samsung Galaxy S6 Edge - Satin Silver (SGP11420)" case
case on the phone. Are there any wireless chargers, that will go "through" that case?
If so, do these chargers charge so fast, that they let the battery health deteriorate? Do they stop charging when the battery is full or is there danger for overcharging or heat building up because of the case?
Thank you guys very much in advance for answers, I'm just really looking forward to the phone and I'm eager to do everything right ^^:fingers-crossed:
You shouldn't worry really. There are rampant unjustified myths about quick-charging. If your device is designed for that feature, the processor and software work in conjunction to prevent damage to the battery. The turbo charger provides large amperage to charge quickly, then reduces at an appropriate level. I've used turbo or quick charging since the Motorola Droid Maxx 4 years ago. Today, those Maxx still function as well as the first day. I do not purchase any device that does not have turbo charging. As far as wireless charging, a decent charging plate should have no issue. I use only TYLT and I build furniture around these things. I put glass top over them and never have problems charging.
Thanks so much
Do all the wireless chargers feature "Turbo charging", or do you mean charging with a wall outlet by that?
I've read in some reviews, that in combination with the S6, the tylt charger tends to fully charge the phone, then stop charging, then after a while commences charging again, leading to the phone screen lighting up and the "phone is charging" notification sound playing, then turning off again when the battery is fully charged and so on.
Did you experience any of this?
@myh0mie I guess we are in the same state, I'm also receiving my S6 Edge on tuesday and have been having the same questions as you have about charging this thread will come in handy
@quangtran1 If you use the fast charger on your S6 Edge, are you also experiencing the screen rotation issues people are suggesting that are caused by the fast charger? I really wanna know how i should be charging my phone to avoid damage once i receive it. Thanks in advance
I myself do not have the screen rotation issue with fast charging. I do know, however, that Samsung has acknowledged this on "a very small number of S6 devices, and has the solution to resolve it". Samsung did not disclose whether this was a hardware or software issue. @myh0mie Wireless charging does not offer fast charging. Fast charging comes from the 2-amp wall block.

Oh cool then it's good to hear that it seems like it's NOT the fast charger that causing the issue and the fact that Samsung already has a solution to it
I haven't had a screen rotation issue either, on a 64GB Edge (AT&T).
As far as methods of charging, seems like the "Adaptive Fast Charging" is definitely the fastest way to charge the phone. The feature only seems to work with the packaged charger, though. I have a few 5V 2Amp chargers that don't charge my phone as fast as the packaged Samsung charger. It's extremely effective when you're very low on battery life, below 25%.
If you look at the Samsung charger label, it says it outputs at 9V 1.67Amp OR 5V 2Amp. The 5V 2A is standard on many chargers. The 9V 1.67A must be the Adaptive Fast Charging.
For wireless charging, I purchased a few PowerBot Qi chargers (very good price and reviews on Amazon) and supplied them with 5V 2A power to keep myself topped off at work and overnight. To me, they seem to charge the phone at about the same speed as a generic 5V 1A power source.
My last phone was a HTC One M7 and I kept a close eye on the temperature with an app called Cool Tool. I still run the M7 in the same operating environment as my S6 and have noticed that the S6 runs 10-15 degrees (Fahrenheit) cooler than the M7 in both charging and non-charging states. Hope that helps.
I have the S6 edge with the TYLT desk charger and the TYLT car charger dock. Neither of them charge the phone quickly at all. I am not a fan of either really, but I use the desk charger on my desk at work and it is fine to keep the phone topped up throughout the work day (I forget it's even there). The car one, however, is going back. It charges hellishly slow, especially if you run any tasks like music streaming or GPS. Not a fan.

My Favorite Iron Stand Integrated Qi Charger 3 Coils

Got this CHOETECH Iron Stand Integrated Qi Charger 3 Coils for my Galaxy S6, Nexus 6 and other Qi devices.
I have several qi chargers and this is my favorite. I was happy to find a stand like this that allows for the phone to be propped up.
It looks cool with metal material, sturdy, lightweight and charged well (at the expected 5V/1A).
Amazon link: http://www.amazon.com/dp/B010B6PSMC
There is a $7 off code CCJJT48V on the landing page. The price will drop to $28 by applying the code. I think it is a great bargain that I could share.
Hope it helps for some of you who are looking for a wireless charger.
CHOE qi chargers are great. I have their t517 charger with a light sensor.
Half the price of this charger stand ($17 only).
http://www.amazon.com/gp/product/B013AB620C
But I'm still looking for a wireless charging stand that support quick charging.
Does it charge the phone in Landscape or only in Portrait? I tend to use my N6 as a Night Clock/Alarm Clock, and so I keep it in Landscape overnight.
Also, is there an LED on the stand to show when the phone is charging?

It is supposed to charge the phone both in Landscape and in Portrait since it has wide 3 coils charging area.
Does it work with case i-Blason **Dual Layer** [Kickstand] ?
This looks great, I wish they had the quick charge feature. Only deal breaker for me but my nexus 4 would love it. Great find. Thanks for coupon!
i got the samsung wireles charger, only the regular wireless charger not the fast charger. how come my N6 wont charge when the phone is OfF? when i put on top of it phone turns ON. also the samsung wireless takes forever to charge my phone. is that how it is? how many hours this choetech charge the N6? does the N6 using choetech can charge when phone is OFF?
The phone switching on when it is being charged is a known issue with the N6. I'm not aware of any way to prevent this.
Regarding fast charging with a Qi charger - the current (low power) Qi spec does not allow for this. There is a draft spec for both medium- and high-power charging, but it will be some time before chargers and devices that can use this technology become available.
Using Qi charging almost requires a different mindset for your device. Rather than letting the battery become almost depleted and then rapidly charging it, I have Qi chargers everywhere that I frequently have my phone (office, TV room, bedroom, car, hotel rooms), so that my phone is normally sitting on a Qi charger and the battery rarely goes much below 100%. If I am away from mains power for a long time, then I have an extended battery pack that I can plug in to the phone (though you can also get Qi versions of these).
Would a charger like this charge through a case? I have a Spigen Ultra Hybrid case (with clear back) for my N6.

Does this charger keep the phone charged after it reaches 100%?
The charger I'm using now (a Tylt knockoff) will reach 100%, but then stop charging until the phone is removed and replaced. This means if the phone is on the charger overnight, it'll usually drain a few percent between 1-2 AM (when it gets fully charged) and when I get up.

I have this charger and it does completely stop charging once the phone is full. Thankfully the N6 idles incredibly well and I always still wake up with 100 or 99%.
I actually returned this charger though because the LED charging indicator on the side of the stand is obnoxiously bright. Serves as a night light for my room while I'm sleeping.

HELP! Note 3 Neo gets too hot, stops responding!

The phone is 1.5 years old, everything was going smoothly till 3 months ago,when I decided to buy QI wireless charging pad and receiver. The charging pad is rated at 1.5A and the receiver coil is rated at 1A. For some reasons, the charging pins near the battery (where you are supposed to attach the qi receiver pins) don't respond to any charging voltage, whether from the qi receiver or normal wall charger.
So I extended a very thin wire from the receiver chip and connected a DIY micro usb pin to it's end. Now the receiver sends charge to the regular charging port, I know I could just buy similar "forward universal qi receiver" for this purpose, but that's the same apart from looks.
Anyways, last month the receiver coil got detached from the micro usb pin, so I stopped using wireless charging and started using the regular wall charger (stock samsung, rated 2A) again. I will buy that forward based universal qi receiver later on.
Since then, the wall charger gets quite hot and the metal part of the usb cable (which is inserted in the charger) gets TOO HOT. The phone's motherboard gets TOO HOT, I have removed the battery cover and inspected, the battery isn't the culprit, it gets a little warm as usual. Phone stops responding to touch and buttons. This happens especially when 2G or 3G data is on, but no apps are running in the background and no sync,downloading/uploading is going on. The phone lies in idle state with screen off and mobile data on.
The phone doesn't get this hot when:
1. I charge it via other phone/tablet chargers (belonging to parents), I have tried with 3 chargers, rated 1.5A, 1.2A and 1A. None of these 3 result in overheating EVEN IF I keep the screen on and use games, browser etc!
2. Charge it while switched off.
3. I had a charging cable of a cheap micromax phone lying around, it's not a data cable, simple charging cable. This cable doesn't result in overheating even with with the stock charger.
4. Once the battery level reaches around 70% (regardless of charger and cable), it doesn't get hot even with mobile data on, screen on and playing games etc.
FYI, The wireless charging setup didn't result in the phone getting this hot ever. As you all already know, the charging pads and receiver coil get quite hot but they also cool down quickly. Also the intensity of heat produced by receiver coil is not too high so as to heat up the whole phone. NOTE that I was using the charging pad with the stock samsung wall charger for that 1 month (maybe that ruined the stock charger somehow?).
Obviously if I start using the wireless charging setup again, this problem won't crop up. But I need to know whether there's any hardware damage/problem or not. To avoid this problem, I could buy another charger of lower amperage, like the moto e charger.
INFO: The phone is SM-N750 3G (Indian version) with no hardware changes. It's running on a custom rom "Unikat V5", alongside the custom recovery "Philz touch". I had installed this custom rom around 10 months back. Overheating problem started ONLY after trying out that wireless charging setup and removing it.

Review of the Choetech T513-S 3 Coil Wireless Charger

Ok, I finally got the Choetech T513 charging pad. I was given a 40% off code if I'd do a review. All in all it's a good charging pad. I didn't want a round charging pad because I don't like how the phone hangs off the edges so when I put a back on my S5 to charge it wirelessly I bought first the pad Samsung made marketed for the S5. That little round thing I hated. I then saw the one that was marketed for the S4. This is what I settled for http://www.amazon.com/gp/product/B00F358AVI?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00 The biggest problem I had was if you didn't have the phone centered just right the phone would repeatedly keep notifying that it was charging. Wife got upset more then one night. The Choetech is a lifesaver with 3 coils in it so you don't have to center the phone so much. My biggest complaint: it doesn't come with a wall adapter. I was told the adapter for the S7 won't work so I ordered a Quick Charge 2.0 wall charger to charge the pad.
Now for the charging times. I tested With the Choetech in fast charge mode. I tested with the S7 wired charger and I pulled out a 2.1a Samsung charger. I'm a little surprised by the numbers reported but I'm just gonna report what the phone told me. At 34% the S7 wired fast charger would take 59 minutes to fully charge. The 2.1a charger would take 1 hour and 9 minutes. The Choetech charger came in at 1 hour 23 minutes. Not that I was worried about the charging times. I wanted the charging pad for my phone at night. This is when I learned the Galaxy S7 apparently has some kind of a fan in it. When I put the phone on the pad I noticed. With no other noises I could hear a very quiet fan. I thought it was the charger. I tested my wifes phone and same result so I emailed Choetech about it and I quickly got a responce. I wish other companies responded that quickly. She explained Samsung is aware of the fan noise and if I turned off Fast Charging I wouldn't hear it. She then attached a pic of the setting in the S7 battery area that shows where to turn off fast wireless charging. The phone even mentioned I'd hear the fan noise in fast charging mode. All in all I'm quite happy with this charger. Yes it doesn't come with a wall adapter but there are other fast charging pads that do that are much more in price.
