[Q] Which Wirless Charger?

What wireless charger do you buy for use with this phone? Thanks.

well if they ever decide to release pricing and availability information I wouldn't mind grabbing the Fatboy Wireless Charging Pillow for the new Nokia phones.

This is probably a stupid question, but presumably the wireless charging won't work if there's a case between the back of the phone and the charging unit?

As long as the case isn't metal, it should still charge.

Since it appears Google isn't making their own, can someone list a few good wireless chargers compatible with the Nexus 4? Thanks.

just do a google for " qi charger" you'll find a few

The Palm one is compatible?

Nope!

I would my best bet. The wireless charges that the iPhone use like that energizer pad?
#Galaxy Nexus HSPA+

Any QI Charger will charge the Nexus 4.
Touchstone chargers will not work.

Possibly this or the one-position variant of that product.

I have one of the Lumia 920 fatboy chargers, will that work?

I had the Nokia 900 wireless charger from Verizon and it wouldn't work correctly w/ my N4. It kept cycling from charging to not charging. I know it wasn't the chargers problem because it works fine with my dad's DNA. So not sure if I've got a faulty N4 or if the charger just isn't compatible. Anyone else try it?

I have the energizer wireless charger, while it works perfectly with my nexus 4, I must recommend against it.
The reason being the back of the nexus is glass, the surface of the charger is glossy plastic and combined with the slight angle of the charging surface, my nexus is happy to slowly slide on the charging surface.
Easy fix by putting some glad wrap on the surface, but detracts from the clean look of the charger

Exact same problem here (charging-non charging cycle). Neither the wireless charging stand nor the wireless charger on the JVC sounddock works for me (both say they should work with qi compliant devices however)

I'm waiting for a Chinese qi charger...

nexus 4 wont charge wireless

I have a nexus 4 that i just gave to my gf because i got a nexus 5. First i ordered a cheap qi charger on ebay that worked for awhile but after i returned the n4 to stock it wouldn't work...it would recognize the charger but would give a blinking light "error" on the charger. So I then bought a nice Nokia dt900 charger off ebay for the both of us thinking that the cheap ebay one from china was junk. Well its the same problem. My nexus 5 works great on the charger but the N4 wont charge. Like I said it recognizes the charger and the symbol on the battery (bolt) will go on and off every 5 or 10 seconds.
Anyone else have this issue?

It's finicky. The sweet spot is below center. I leave 1/4 inch of my dt900 exposed below the phone and it's always charged by morning. It does do some blinking but it gets the job done.

its def something wrong, cuz neither one will charge it right. But i have no idea how i would fix it. I dont see how it could be software especially being on stock 4.3
Update: Now its charging fine on the cheap ebay one but keeps going back and forth between charging and not charging on the nokia dt900. The nexus 5 charges perfectly on the nokia...i dont get it

[Q] Third-party Qi charging pad help?

First, I'm new to Qi charging, so please forgive (and correct) any mistaken assumptions I might have!
Anyways, based on the Budget Wireless Charger Showdown: 5 Qi Chargers all $11 - $15 shootout in the Nexus 5 forum, I decided to purchase a few Qi chargers. I received them and tested them with my friend's Nexus 5, confirming that wireless charging worked. Pretty neat!
A few weeks later, my Galaxy S5 wireless charging back FINALLY came in. I put it on my phone, put the phone on the charger, and nothing. I tried all the chargers, no luck. Nothing charged. But the Nexus 5 charged just fine. Assuming it was defective, I returned the charging back and ordered another one. Same thing. My phone doesn't charge on these chargers. The backs are both official Samsung accessories, bearing the Qi logo.
Is it incorrect for me to assume that all Qi charging backs will charge all Qi phones? Could my phone be defective? Any troubleshooting ideas?
Regardless, I'd love a recommendation for an inexpensive Qi charging back for my Galaxy S5. I'm going to need 3 or 4 of them.
Thanks!

Thanks for the response. Unfortunately, the Qi charger you posted there costs nearly $50. Did the price go up?
Also, the photos of that unit look identical to the chargers I've bought (that don't work). I wonder if they're the same or different internally... Hmmn.

Geez.. That was $18.90 when I posted it last week. There must have been a run on them.
They were a good source because they were in New York most of the other sellers of this model are in China.
Edit: They're selling the White pad for $17.95

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!!!!

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!

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?

New Phone Unresponsive after Charging

I received my first Essential phone for Christmas and everything worked fine the first day of use. I left the phone to charge overnight on the official charger and the phone was unresponsive the next morning (no charging indicator, LED, etc.). I tried holding the power button on for an extended period of time and tried to boot into recovery mode, but nothing happened.
Amazon sent a replacement that arrived 2 days ago. I set up the phone again and it worked fine the first day. After leaving the phone to charge for a while the second phone also became unresponsive with the same symptoms as before. I should note that with the second phone, I used the charger from the first phone to charge it too.
I'm now waiting for yet another replacement and I'm assuming there's an issue with my charger since that's the common element between both failures.
Has anyone else experienced anything like this?

This is seriously the identical situation I'm in right now. My second replacement phone that I got 24 hours ago, just turned off shortly after connecting to the charger. Became completely unresponsive. No indicator light, nothing. Happened to my for a replacement as well. Identical. Waiting to hear back from them to see what they are going to do. Honestly I just want a working phone at this point. This is getting frustrating.
Let me know how your experience goes or what they say. I'm at a loss.

Do either of you have another charger to try with?

It never happened to me and I've been using the stock charger as well as the 6P and 2 other aftermarket chargers from Amazon without issues.

I've tried multiple chargers and multiple AC bricks so far, and even a few different outlets around the house.
They want me to send the device back tomorrow (without a working phone in the mean time.) So they can inspect it and see if there's a "defect" before going any further.

Otherwise, I've used a samsung charger, an Anker charger with an adapter, an old Apple wall charger, some random costco charger, no issues.
