This is supposed to be released soon I think. It's what I am waiting for. I have found nothing else suitable.

Hello, I'm new to the forum, but I thought that if someone would know this its people in this forum, so the problem is that my nexus 4 is not able to charge. It gets all the red light things etc. i tried most of the stuff recommended here in the forums, non helped so I decided it could be hardware related and since I have no warranty left I opened it up. After testing many possible problems and checking stuff suggested in the service manual I found out the problem: The battery is at about 2,3V now, the charger itself provides 5V, but only 2V of energy comes to the battery when charging. I mean 3V dissapears on the way to it. I've checked almost every charging spot with the voltage meter and the whole 5 volts go through all the charging connector. Which you can buy on ebay and easily replace.
So it's a very short distance of the board left where the voltage could be disappearing and I can't seem to find where exactly. So if you have any ideas, please help.
carry out a voltage drop test on both positive and negative side to try to isolate the problem

All the voltage testing gave me nothing. So I charged the batter back to 3,8V using external power supply with custom voltage and now when you check the voltage on charging spots on the board most say full 5V or at least 3,6V... But the phone is still not working I reassembled it and tried to turn on but it shows google logo and turns of, if you go to recovery mode it also immediately turns off and if i just leave it on a usb or charger cable it's solid red light... Any ideas?
So, I'm not sure what the issue is here. I purchased the official Qi charging cover for the S5 and the official Mini Charging Pad.
Every time I try to charge my phone on the pad, it goes for an hour or so then the light starts flashing orange. Charging pad works fine with my Nexus 5 and Nexus 7.
Any ideas? I've seen other scattered reports of this on the web but no solutions at all.
I'm getting the same issue and I thought it was just poor placement on the mat. But I have tried it placed in different places on the pad, none of which made a difference. I also thought it was possibly the Diztronic cover reducing the efficiency of the charge, so I removed it to charge the phone. Nope, same issue. Using the supplied cable and the 2A Samsung charger supplied with the S5.
The problem comes when I set it away to charge overnight, and I wake up to find there's no full charge (once worried when it only had 36%, not enough for my day).
Every time it fails, the orange indicator flashes on the Samsung charge pad.
It's starting to annoy me
I use a similar setup - mini charger with sview charging back.
The orange light indicates not enough power getting to the pad - try changing your cable. I'm using a blackberry playbook charger 1.8A - 5 dollars on amazon to power it now and it works fine. I'm about 6 months into it..

I was using the supplied wall wart and cable that came with the Mini Pad. Just took the thing back and bought a Tylt Vu instead. Charges perfect.
Kinda sad that a Samsung Qi pad and a Samsung Qi backplate on a Samsung GS5 doesn't work properly.
there is already a thread on the oem cover and charging transmitter, also i have posted within the thread about this problem.

I've tried 3 different cables and 2 different 2A chargers. Still have issues.
2 of the cables are Samsung ones (one of which came with the Samsung plate), and the other from my Nexus 7.
Chargers are Samsung's 2A supplied with the S5, and Asus Nexus 5 2A charger.

orange led means error, flashing green led means less than 2.0a power supply is used, lit green led mean a 2.0a power supply is used.
it's a detection or compatiblity issue with the transmitter and receiver, whether it's oem or 3rd party product used.

sorry I never provide links, use the search function, it will show up.
Don't waste your time trying to fix the problem. Its an issue with the Samsung mini charging pad. I replaced it with a 3rd party 3-coil charger and all the problems I encountered (charging error, erratic charging performance resulting in constant waking up of the phone, etc) disappeared.

Same here, and the same recommendation from me. The Mini Charger is junk.
The mini charger has compatiblity problem, works fine with my nokia lumia 930, and S5 using a yijieneng receiver, but has problems with it's own qi cover and a few other receiver.
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!!!!
The "old" Samsung S-Charger does not work either.

Thanks for that info, I've ordered a Nokia DT-601 from the whitelist, fingers crossed!
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!

Thanks matts2 for sharing the list
I bought a Nokia-601 (£12.99 of Amazon) an it works perfectly, I've just charged from 35% to 100% with no issues. It even comes with its own 1.5amp mains usb charger

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?
Hello there folks,
I'm thinking about adding wireless charging in my car for the Axon 7 with an universal charge receiver for the Type-C port and a Qi fast charger with magnetic hold. Specificially I want to the the following combination:

https://www.aliexpress.com/item/Ori...uxury-View-Window-Leather-PU/32694755153.html
Does anyone of you have experience with it or something similar? Please share it for me... is it functionally?
Since Qi charging works best being in close proximity as possible to the battery, you may run into heat issues since the qi pad will be on the outside of the case. You can always order one & try it. Just keep an eye on the temps
