Qi charging problems

I ordered the official Samsung wireless cover from Amazon, slapped it on, and then put my Otterbox Commuter series over it - so far so good, everything fits reasonably well.
I go to put my S5 on a wireless charger and it charges. Then stops charging. Then starts charging again. Then stops again. Over and over it repeats this.
I get to thinking the phone is just too far away, so I take off the hardshell of the Otterbox Commuter. Same thing happens again. So I take off the soft shell - now I'm down to just the naked phone, and it's still charging on and off.
I'm using the blackberry folding blade wires, and the chargers found here: http://forum.xda-developers.com/goo...udget-wireless-charger-showdown-5-qi-t2676249
Specifically, the tilted charger and rectangle with LED lights. Both are giving me the exact same on & off problem.
So does anyone know how to fix this? Is it the chargers or something I'm doing? Are the chargers just not generating a strong enough field (if so, which charger can I get that will generate a better field?)
Thanks for any help
EDIT: Clarified that wireless cover is official Samsung

I had the same issue with a cheap receiver I bought off ebay. The receiver was junk. I took it out of the phone and dropped it on the mat and used a multimeter to check my voltages and never got consistent readings. Tried again with the same chinese mat and the official back and no issues at all.

I am having similar issues using a Palm wireless charger I custom made. I believe the issue is the connection from the cover to the pins on the device next to the battery. I am going to try adjusting it. Also, putting the phone in power saving mode before wireless charging seems to help. Think it may have to do with the wireless charging coil not providing enough amps for the phone to keep up. Trying a different cable/wall charger may help.

It could be the output isn't high enough. For the official mat you need to have a 3 amp charger for it to work. And if the output is too low, the phone may be getting confused because it is detecting a current, but not enough of one for it to be registering that it is charging. I have a car charger that has a 1 amp and a 2 amp setting, and when I try it on the 1 amp setting I get the same issue where it connects and disconnects. 2 amp and I get 0 issues.

I have a similar issue. I'm using the official Samsung S-View Wireless Charging Cover with the Nexus 5 wireless Charger. I get nothing when I put them together. I believe the output from the charger is around 2 amps and it works perfectly with my Nexus 5 (surprise, surprise...) Not sure why I don't get any response whatsoever...

I'm using a blackberry folding blade charger, the stated output is 1.8 amps, and my Samsung charger that came with the phone is 2.0 amps; both give me the on/off problem. Is 3 amps really the key? Where do you find one?

Sorry meant to say 2 amp. But you may want to test your mat and receiver and see if it really putting out the 1 amp the other thread said it was supposed to. If you are getting an output of less than 1 amp that the other thread says it should be then that is probably your issue. Unfortunately I'm not able to measure the outputs on either of my mats to give you an idea until later this evening when I get out of work.

I think you may be right; it may well be the mats I have are just junk, both of them, unfortunately.
I opened up the back of the phone, and brushed off the wireless charging prongs, just to make sure they weren't dirty. Put cover back on, put otterbox commuter case back on.
Put it on the wireless charger, it cycles on/off again and again, about once per second. Take off the hard shell, leaving just the soft shell, and it cycles on/off about once every five seconds - that is, the interval actually got longer. Take off the soft shell, down to a naked phone, and works after cycling on/off about 5 times, then it settles down and stops cycling.
On another charger, the tilted qi charger, it'll charge if the phone is naked, but if I put even the soft shell of the Otterbox Commuter on it, it'll cycle a few times then just not charge at all.
I'm not sure this is a connection problem with the prongs, or a problem with the wire/charger. I think it has something to do with the field that the qi charger is generating. Since I don't know jack about the qi standard, can anyone tell me if all qi fields are equal? That is, do higher quality qi chargers produce a larger or strong field than cheap units?
Like I said in the OP, these are all very cheap chargers, $15 at most, and I'm wondering if that may be the cause.

I use the 2A charger that came with the phone with the CHOETECH pads. The insert is the CHOETECH mat inside the cover. The pad is rated 2.1A input, 1A output. My phone cycles on-off occasionally when the phone hits 100%. I use the Otterbox Defender case.

Interesting, so could the problem be due to just using a cheap generic? Seems that the cheap ones may be generating a smaller or weaker field?

Just wanted to post an update - bought a more expensive charger, one with 3 coils instead of the 1 that was in my other two - and now it charges fine, right through my Otterbox Commuter case.
So to anyone else having this problem - the field generated doesn't seem to be big enough to penetrate the Otterbox Commuter with just one coil, you need 3 or so.
EDIT: Specifially, it was the Cheotech Qi wireless charger, rectangle with LED

it's not the problem with the coil, they give out the same current, it's because the angled charger is a cheap and nasty one, and the flat one is just a fake one, the official one cost alot more.
3 coils only give you a wider surface detection, the current is just the same as a single coil or a 7 coils.
The 3 coils charger you have is a rebadge of powerqi T300 which is a highly recommended one.

Does the Note4 support wireless charging?

I haven't seen this covered and if it has been, I'd appreciate anyone posting a link to the article. Does the Note4 support wireless charging or will we have to get one of those stickers as we have to do for the Note 3?
Thanks in advance
nevermind, answered my own question, same crap. How come they can include wireless charging in the S5 but not in the Note4? Seems like they did some great stuff that seemed very basic and rushed the Note4 out without the same tech such as dust and waterproof. I don't get it.

I have been wondering the same thing. I certainly won't get one unless it has Qi charging. I am assuming they will release a wireless back cover again.

I don't want to buy another back or another "sticker". How is it other models have it built in and this, their "latest" version doesn't? This is truly a step backward in the Note series. Huawei's devices are looking very nice right now.

I wonder if the quick charging will work with wireless charging?

No. They are two separate things... a given Qi charger only puts out a limited amount of power.

Do the Huawei phones have wireless charging? After you mentioned Huawei I checked out some of their best devices but couldn't see any wireless charging options.

If it is wireless charging, does it mean it will have a magnetic back? I need that so I can stick it to my car CD slot caddy.

^^What he said^^ and theres no way any wireless charger can do that, also given my experience with the LG G3 I am not ruling out damage to the battery or device due to overheating whilst wireless charging, my battery life on G3 perished after such time as I started using wireless charger.
I may be wrong, however, its fairly coincidental.
On a related note the pins are definitely there for wireless charging but no coil as far as I can tell.

Note 4 DOES support wireless charging with the correct door and or cheap coil which im sure will be available soon.

Glad to hear that it supports Qi charging (with add on). Since going wireless on my Note 3 I'll never plug my phone in again.

I'm pretty sure the reason the Note wasn't certified dust and water-resistant is the large long opening in it to accommodate the S-Pen.

I don't see why Samsung or any smartphone company hasn't started using the vapor/nano-coat waterproofing. It wouldn't matter how big any hole is. See HzO, P2i and others.
The day I get my Note 4 I'm sending it in to get 'vaporized'. Only ~50 bucks, totally worth it for a $1000 device that fits in your pocket.

Idk why Samsung doesn't include the wireless charging back to begin with. That way all the cases would still fit it. It's irritating to say the least.

Same here. I use the stock samsung wireless cover I think I got for 20 bucks for my note 3. It works great with the TYLT and I don't use usb anymore. Even when traveling I have a portable battery "ravpower" with QI built in and it works great.

Because then they couldnt charge you the $40 for a new back.

Qi wireless charging

Has any one any experience with wireless charging on the Yotaphone 2? It supports the Qi standard but I've not ever had any device that can be charged wireless so I don't know what to expect.
There are some cheap chargers on ebay so I may get one to experiment with but wonder what others are using, how long a charge takes? is there a tiny sweet spot to get it to work? does it get hot? Any compatability issues?
Thanks

Hi there,
Yeah actually I got one for my YotaPhone 2, it's ADATA Elite CE700.
First I have to say I was very disappointed because apparently you can only wireless charging the YotaPhone2 with the main screen facing up! Also you should know that the spot where Qi located is a bit small (3cm in height in the middle of the EPD Screen), but that also depends on the type of wireless charger you would use. Something like Tylt Vu would Support more area thus its more hassle free.
It's also good to know that with wireless charging you won't get Quick Charging anymore. Because In order to do that you must use the MicroUSB port. But again how long a single charge takes depends the type of the Wireless Charger and the amount of output current it has which most of them are 1~1.5A.
For your last concern, any Qi Wireless Charger will do but try to get one of the Tylt Vu. It has the best reviews. And the phone won't get hot during wireless charging if you must know.
And something which I'm not sure whether its my wireless charger or it's general, is when the battery is 100% the charging won't stop, unlike the normal charging with dedicated adapter which cut the current when the charging is complete.

Hi, thanks for your detailed reply, I've now ordered two different generic chargers off amazon to experiment with, they are coming from China I think but were less than a tenner, I'll report back on these after ive used them for a bit.
It seems less than ideal for me to have to charge with the EPD facing down but I guess this is an engineering limitation. I'm sure there would be advantages and disadvantages of each side facing up during wireless charging.

I recently bought the Nokia DT903 wireless charging plate.
It works effortlessly with the Nexus 5. I can pick it up and place it back for charging with no connection worries.
With the Yotaphone 2 it does work, but it has to be in EXACTLY the right spot.... I'm talking millimetre precision here.... it becomes really frustrating to use and spoils one of the key benefits of wireless charging.

That's what is worrying me about Qi charging, I like the idea of wireless charging for the convenience, I work shifts and fiddling with the usb cable when I get in can disturb my partner, just being able to lay it on my night stand would be great, but sometimes I check the time on my phone in the middle of the night, or get up for the loo and nudge the charging cable and move the phone and if its really fussy about how it sits on the charger then I could end up with the phone not being charged overnight.
The ADATA Elite CE700 mentioned by Parisabs4 above looks like a good solution as it is adjustable and with the phone sitting on the cradle it is hopefully easier to hit the sweet spot.

QI charging experience
Okay so I've now tried 3 different Qi wireless charging plates and I have found that all of them exhibit the same problems whilst attempting to charge my Yotaphone 2
In the picture there are 2 single coil chargers and one triple coil charger (the one that is not flat) they are budget models, costing between £4 and £7 on Amazon.
I can get the Yotaphone to begin charging correctly on all three chargers, the phone says it is charging and the qi devices LED blinks to confirm charging. After 10 - 15 seconds the Yotaphone & chargers will stop charging, the indicators on the phone and charges indicate that charging has stopped. After a couple of seconds charging will recommence for about 15 seconds and the stop again, this cycle repeats for a few times then charging stops all together. Lifting the Yotaphone off and then returning to the charger will recommence charging.
My conclusions are that
My device has a faulty wireless charging receiver. (This is unlikely as im on my second device with the same symptoms after an RMA for a previous fault)
The charging software in the Yotaphone is buggy.
The Yotaphone is not fully compatible with the QI standard.
The Qi chargers I am using are not powerful enough for the Yotaphone. (Unlikely as I've now tried 3 different chargers but they were cheap!)
Has anyone else experienced this problem or is using a charger that is proving reliable?
I'm tempted to try the official wireless charging block as it ought to be compatible with the Yotaphone but its £40 wasted if not (although it can charge via a usb port too)
WHY IS NOTHONG EVER EASY IN THE TECH WORLD!!!!

As a footnote I have found my tablet charger (a 2.1amp samsung) works with one of my qi charging plates to charge the yotaphone but any other 2.1amp charger exhibits the same problems as the regular 1 amp chargers I've been trying to power the qi plates. Also I've discovered the Yotaphone will not charge from the usb socket in my car but any other device I connect to the socket charges fine, this is one flakey device!

I bought a cheap nameless one, have yet to receive it, I hope it will work in combination with a powerful adapter. Anyone got these cheap (5 USD) chargers working with their phone?

Another good QI charger for YP2 is/are the ones that IKEA sells. They have several models, but all seem based on the same platform powered by a 19V DC adapter.
I couldn't get any cheap QI chargers to work reliably with my YP2, but the IKEA chargers work great. They have some margin in positioning the phone on it, and prices start at around $30/EUR 25, so not to bad. I cannibalized the electronics from a JYSSEN to transplant them into a custom 3D printed charger case.

Does anyone have any experience using this Samsung 2A charger with the Yotaphone 2?
https://www.amazon.com/Samsung-EP-PG920IBUGUS-Wireless-Charging-Charger/dp/B00UCZGS6S/
UPDATE: Never mind, I ended up buying the Nokia DT-900 since it's on the official list of supported chargers.

I bought my first wireless charger , a cheapo one from China just to see how they are. Cheap as in 4 USD. It does work but exhibits behaviour like described above. All night only charges it a little and the on light is not on much. I thought it was a problem with a cheap charger, but maybe not, it sounds like Yotaphone firmware. I don't have any problem finding the sweet spot.
I was reading about new LG fast charger that is coming out soon, first ever fast 15w wireless charger. But of course it will be expensive .
http://m.androidcentral.com/lg-announces-new-super-fast-wireless-charger-get-you-cables-good

I bought an 3-coil-qi-charger-stand from China (eBay article 381639407985) about 10€. It works perfekt.
Cheap Single coil charger work also, but only if you place the Yotaphone at the exactly right position ( only 2mm tolerance). As the coil inside the 2,80€ single-chip-computers charger from China is often not places correctly inside the housing, you first have to correct that.
So tripple-coil is to be prefered.
One nice thing: Charging via QI and USB-OTG works fine at the same time on Yotaphone. You can put the Yotaphone 90 degree rotated on the 3-coil-charger-stand and watching Videos from a USB-Stick.
I even think about building an own small OTG-Adapter, using a extreme small micro-usb-connector (like used in universal QI reciver-plates), a very small USB-Micro-SD-Reader, some wire and epoxy. The SD-Reader will be placed on the lower frame of the ePaper. I use a bumper and would cut the neccassary space out of it. So I could build an nearly invissible (with bumper) SD-Card-slot. 64GB extra space is nice...

I'm using a Nokia DT-910 that I originally bought for my Nexus 5 a few years back.. works just fine with the YotaPhone 2..
No need to be careful with positioning or anything like that.. just put the phone on it and that's it.
The benefit of a charger like this is that you can actually see the screen while charging instead of it being flat on the table like some other models.

Never thought about it but they do seem quite common https://www.youtube.com/results?search_query=qi+wireless+powerbank
Or you can easily make one yourself by taping a wireless charger to a powerbank

In that case there is a wire, between PB and Wireless charger. �� so NOT wireLESS, lol

Can I use a QI Wireless power bank to charge the Yotaphone in my pocket?
Sometimes my phone runs out of juice. Is it possible to buy a power bank with wireless charging capabilities and use it to tirelessly charge my phone, by placing the power bank in my pocket next to my phone?

LG G4 QI Wireless Warning / Issues

I bought the CFR-100 Quick Circle Case with the QI coil, and was planning to rip it out but the case is actually quite nice so I'm using it as is - but be warned. The power requirements of the G4 seems to cause issues with existing QI pads (but I would hope not the official LG one) - I have tried it on a Maxell Dual coil pad, and it didn't work at all (the light just blinked and nothing happened on the phone), and on my Panasonic QE-TM101 moving coil pad it didn't work either, until I took off the clear plastic shield that comes with the pad, and even then to get it to work it is touchy and requires me to press down hard on the phone/pad for a few seconds to get the charging going....so it sort-of works with the Panasonic QE-TM101.
Edit: a friend has a white version of the QE-TM101 (mine is black) and it works all the time, no issues - but on mine, the issues are as above....it still doesn't work at all on the Maxell dual coil pad.
Edit 2: It may be variations in the quick cover case because it is all VERY touchy.....I took apart my black QE-TM101 and lengthened the spring that pushes up the coil, I also poured boiling water over the top cover to try to warp it inwards - and this has now made it work better, not 100% but 9 out of 10 times it will charge now without me pressing down on it.

Now that's weird...
I seriously cannot understand how LG decided to drop proper Qi support. And now, if it's going to have problems with even additional accessories, it's worse.
I'm using Nokia-101 which works flawless on my G3 even with a hard plastic case. Wondering if it supports Quick Circle considering it's one of the first (if not the) Qi chargers.

I have the Tylt Vu (http://www.tylt.com/vu/) which I had been using for my Nexus 5.
It's just not working with the G4 official Quick Circle case
It's weird because the G3 is listed as compatible. I'll try again later today but I'm not expecting anything.

I have ripped the official sticker out of the circle case and stuck it into my brown leather back and it charges great on both the official qi charger and this rather cheap one Qi Charger maybe you have a faulty one?

Hm...

Thought to buy just the QI sticker and put it to the original leather battery housing back. Do you see any issue with the leather back being hot during the charging? This is the only concern I have about it.

I have the Tylt Vu (http://www.tylt.com/vu/) which I had been using for my Nexus 5.
It's just not working with the G4 official Quick Circle case
It's weird because the G3 is listed as compatible. I'll try again later today but I'm not expecting anything.

I have the same Tylt charger & it works fine with my H815. I have the Quick Circle Case. Which model do you have? If it's the AT&T model, it's Powermat.

Thanks for letting me know.
I have the H818P
It's not carrier locked, I didn't buy it from a carrier, although I'm not in the USA either.
I tried different positions again yesterday but nothing... It's still working fine with my Nexus 5

Thought to buy just the QI sticker and put it to the original leather battery housing back. Do you see any issue with the leather back being hot during the charging? This is the only concern I have about it.
Thanks!

I haven't noticed out getting hot at all

Thanks!

FYI: Those stickers are on Amazon (Prime, too) if you're interested. $15.
I bought one yesterday.

I bought one off Amazon and installed it yesterday. It was a pain to get on right but it works perfect now

More power
I bought the quick circle case and was also having problems getting it to charge. I have a dual device Energizer pad and a cheap eBay pad. Neither was working with the quick circle case. Tonight I tried plugging the eBay pad into my 2A USB charger and it started charging. If you are having problems, try a higher power source for the charging pad. The Energizer pad still doesn't work, it has a non-USB plug power source.

Do you have the amazon link. I can't find the prime one. All i find are ones that won't arrive until Mid-July...not acceptable.

The one I bought days no longer available

The one I bought ended up not working on my Zens charger, so maybe you dodged one.
It was this one:

QI stickers burning internal chip ...?
Hello,
Reading through XDA forum, I got the understanding that QI stickers (at least some of them) are not working very long. Some experienced troubles, despite changing sticker / pad to different brand/model.
Is there any really positive experience on long term?
And if yes, please share what sticker and charging pad you use

I have some cheap off-brand wireless charging pad+sticker, and it works, but it charges so slowly it's hardly worth using, and the position has to be just right.

This thread has some great info on the stickers and chargers various people are using and the experiences they've had. My post from the thread is below. I'm still using the same sticker and charger daily, and I've had absolutely no issues. A good quality sticker and 3 coil charger go a long way towards minimizing issues.

G4 Model: Verizon G4 (VS986)
Sticker or Official: NeWisdom (Upgraded Chip) sticker via Amazon
Qi Charger: CHOE Stadium Qi Wireless 3-Coil Charger
Launcher: Nova Prime
DPI Used: Stock
Alarm Usage: Rarely
I installed the upgraded NeWisdom sticker a couple weeks ago, and I've been charging wirelessly each night since then. I have yet to experience any lockups. It does get hotter and charge slower than my previous phones that used OEM wireless charging backs (Galaxy S5, Note 4) or came with wireless charging built-in (Droid Turbo) when using the same wireless charger.

There is another thread around here with more information (Qi Charging Woes). Mine magically just got better. No more lockups at night, or anything. Maybe LG was pulling data at night and found it was causing lockups and tweaked the backup scripts. Lol. Kinda weird it went from 3-4 nights a week to none at all.

Quick circle case
whiskymobile said:
I bought the CFR-100 Quick Circle Case with the QI coil, and was planning to rip it out but the case is actually quite nice so I'm using it as is - but be warned. The power requirements of the G4 seems to cause issues with existing QI pads (but I would hope not the official LG one) - I have tried it on a Maxell Dual coil pad, and it didn't work at all (the light just blinked and nothing happened on the phone), and on my Panasonic QE-TM101 moving coil pad it didn't work either, until I took off the clear plastic shield that comes with the pad, and even then to get it to work it is touchy and requires me to press down hard on the phone/pad for a few seconds to get the charging going....so it sort-of works with the Panasonic QE-TM101.
Edit: a friend has a white version of the QE-TM101 (mine is black) and it works all the time, no issues - but on mine, the issues are as above....it still doesn't work at all on the Maxell dual coil pad.
Edit 2: It may be variations in the quick cover case because it is all VERY touchy.....I took apart my black QE-TM101 and lengthened the spring that pushes up the coil, I also poured boiling water over the top cover to try to warp it inwards - and this has now made it work better, not 100% but 9 out of 10 times it will charge now without me pressing down on it.

Nexus 5X - Qi Wireless Hack Mod

https://www.youtube.com/watch?v=imhoFe4bbFU
neat mod, but seems that it still needs further testing since its so new. qi charging at the end of the video.

very interesting, hope to see a video on how they do it!

I have to believe it is something like the Tylt Vu. It has three coils and is quite tall.

This mod makes me happy as I wait for my N5X to be delivered but that theme just brings back a memory from the only time I've shedded a tear in a video game.

very interesting... Still really risky, you will have to void the warranty to do this and if you don't shield the heat or if the wire touches something wrong it could brick. Just be careful guys. Zsnaps is a safer alternative that makes charging simple. Wish they would ship already

not charger. but a receiver pad.

Why can't someone make a bumper case for the 5X that incorporates a Qi charging coil and plugs into the USB socket? I think there are auxiliary batteries for some phones like that. That would work for me.

im sure someone is going to make one. but not everyone likes to use a case.

Agreed. And (surprising to me) not everyone likes wireless charging. I hope the intersection of the two (and the 5x community) is big enough to warrant market attention.

I asked the poster ,xCubicle....
What's the large light grey patch on the inside of the back cover?
It can be seen in the ifixit teardown images at step 4.
Got the response...
"useless sticker. peeled it off."
I couldn't help but think back to the AMA
specifically the part "...Meanwhile, wireless charging adds z (thickness)..."
So what's the deal here with the blatant capability of qi wireless being designed into the rear case but the spec being deleted...?

It's because they did not want to give qi to the 5x and leave it out of the 6p because it has an aluminum body.

I'm pretty sure you hit the nail on the head here.

It wouldn't have been as bad if they'd just said that, but the bull****ting about thickness as an excuse is not cool.

after further testing with the mod. i am indeed able to charge wirelessly up to 100% from 0%. i measured the wireless charging current and it seems to range from 100-500ma charge rate. a typical charger ranges from 1000-2500ma charge rate.
regardless, its a working mod so far.
i need to refine the wiring to layout to make it a bit more appealing before i offer it as a modding service.

Awesome news. Looking forward to potentially doing this mod myself!

I bought this for my Nexus 7. Yep it is the largest one, you can even buy it from a Verizon store.

Charging time
Can anyone comment on the wireless charging time with the mod compared to the wireless charging time on the older Nexus 5 which had it built in?
In the same boat as many, where the lack of Qi has prevented me from upgrading

What will happen if wireless charging and USB Charging together?

Not even sure what happens now
To answer my own question form my last post. "Even the more expensive Qi modules appear to charge slower than the factory built in modules". Not sure what the reason for would be? Or people do not realize they are buying lower powered (yet more expensive) modules. Most posts I have seen refer to 500mAh modules
