assuming that there has to be a small distance between the charger and the phone to make it charge wirelessly, would it be safe to say that the nokia fatboy would work? (i.e the pillow charger, basically just a pillow covering the DT-900) ... :confused:

since people have been reporting that the has to be a slight distance for the nexus to charge, Im guessing that the reason a naked nexus could not charge and the nokia can has to do with the thickness of the phone...well, the lumia 920 is slightly thicker than the nexus...at least when I held it in my hands it felt that way (in MS store)...
[Nexus 4 Accessories] shogunmark:
I am going to go ahead and bit the bullet.. I can score the nokia charger for $30. I have the bumper on the phone now, but also have a rearth case. If the extra distance trick doesnt work then i will just ship it back. So I should be able to definitely confirm or deny this. Hopefully it ships soon.
[Nexus 4 Accessories] Noodles5666:
I don't know if I would be jealous as I was able to snag a free one.
[Nexus 4 Accessories] shogunmark:
My initial testing with the Nokia wireless charger is a bust. I have tried all the tips and suggestions (using a cloth, or other material in between, even borrowed ideas from the Uniden thread) (NFC off or on does not make a difference).

I thought i was in for a success. I got it out of the package last night, and of course placing it directly on there caused the cycling issue. So i tried several different types of material, cloth, my rearth case, etc.. What finally stopped the cycling problem is that i have a second Rearth case (the first batch defective one) and i used this to cover the wireless charger, placed the phone on it with the top of the phone (not the USB port end) hanging about a half inch over the back of the charger (the plug in side). I had no cycling and within a half hour it went from 68% to 74%.

But i was not going to call this a success yet. I set it by my bed, laid it down on the charger and according to appearances it showed to be charging. About 5 hours later i was woken by a phone call. I missed the call and was unable to turn on the screen (phone was not unusually hot, nothing seemed abnormal). I held down the power button and it rebooted. Upon reboot i was at 54% battery. So without some kind of mods I would call this confirmed busted. Do not buy.

I will perform more tests this week when i am at the office so i can actually watch it and see whats going with it.
[Nexus 4 Accessories] shogunmark:
Since this thing cost me less than $30 shipped, i will keep it regardless. So after i perform all of my testing as a stock unit, i will try to mod it to see what may or may not work. Something i really want to try is to hack in a different power supply. The one provided only outputs .75A. They use a stupid cable between the power supply and the pad. wish they would have used a d@mn micro usb cord. But i wont know whats feasible yet until i am done testing.

So before i make any mods to this later, is there any specific testing that anyone wants me to try besides what i have already mentioned above?

Things already tested:

Case vs No case (Rearth and Bumper)

couple of business cards between the phone and pad

placed bottom side on metal and non metal surface

NFC on and Off

Cloth in between phone and pad

Tests Planned (pre modification)

bringing to my office so i can watch the charge cycles all day

Charge with phone off (i did turn my phone off this morning and did notice it started to charge while off, i did not have time to let it sit though)

I should add though that a Qi charger should not require any work and should just work right out of the box. I am only continuing my testing because i plan on keeping it regardless, and others may be able to get these cheap enough to justify a little hacking to make work.
[Nexus 4 Accessories] jessesam:
Is possible to flip the standing Nokia charger and use a pillow over it to charge ?

If its possible then stand / pillow will be a great combination so that I can switch between those .
[Nexus 4 Accessories] shogunmark:
I'm not sure I would use a pillow. That would more than likely trap a bunch of heat and cook your battery. I would try something thin or something that will dissipate heat easily.
[Nexus 4 Accessories] SilverRubicon:
I am going to try the same thing. Unfortunately, the only power supply I have with the same size tip is 5v but it does provide more amperage. :(

Do you know the polarity of the the tip? Or the dimensions of the tip? I thought I would try to pick something up at Frys or bastardize an existing power brick.

Btw, my charger works sometimes but I haven't been able to find a pattern as to why and why it does not work. Also have not had it charge past 96% but it did get to 96%.
[Nexus 4 Accessories] shogunmark:
I'm not sure on the polarity, but I'll hack mine up. I would actually prefer to have a USB type plug on it, this way I don't have lug different chargers if I'm traveling. So I'll test it when I cut it.
[Nexus 4 Accessories] shogunmark:
*Warning.. Electronic porn

I just wanted to pop the cover off.. So this is what the insides look like
[Nexus 4 Accessories] davigol:
Well if it only cost 75.99 like HERE I'll also consider to buy one ...
[Nexus 4 Accessories] shogunmark:
So here is something interesting. As you can see in my post above, i popped the cover off the pad. So i wondered to myself, what would happen if i just place the phone directly on the coils. Now i should mention that i still have my Rearth case on the phone. But oddly enough it stopped cycling. My phone was 90% and did not charge, but it did stop cycling. I will have to research this further.
[Nexus 4 Accessories] quentin0:
nvm
[Nexus 4 Accessories] the orange bandit:
Any update on your testing? I was able to snag the DT-910 (stand) for $50 with my FAN account at AT&T. I bought the stand specifically because of the angle (I wanted something to prop my phone up) and also for the NFC. If I can't charge with NFC on, then it's pointless.

Also, I can't seem to get the NFC tag to read on my Nexus 4 (works great on my Lumia 920, of course). Figured I might just need an app or something to read/write the tag? I'm completely new to NFC so I'm clueless here.
[Nexus 4 Accessories] shogunmark:
The whole holiday stuff kind of sidelined my testing. But I'll hopefully resume tomorrow... I wanted the stand but it's been backordered on premier.

Is there an NFC built in to the stand?
[Nexus 4 Accessories] the orange bandit:
Yeah I was able to find one at my local store and got the manager to give me the Premier discount (apparently that's supposed to be online-only if you don't have an active AT&T account. Whatever).

It does have NFC built into the base. When I tap my Lumia 920 to it, it launches the Nokia Accessories app, which allows me to choose an app to launch with the NFC. I can't get it to recognize with the Nexus 4 at all.

However, I already sold this thing - have a buddy with a Lumia 920, so this way he gets the stand that's sold out everywhere, and I don't have to hassle with the return. I can get the ugly Energizer pad for roughly the same price anyways.
[Nexus 4 Accessories] Made2Last:
I purchased the dmt-900 from my at&t store for my brother for Christmas. His phone would not stay connected, and mine would connect but after 15 minutes of charging it went from 85% to 84%. Some standard. He returned it today I believe.
[Nexus 4 Accessories] FallN:
Get the "ugly" Energizer pad, lol. (BTW, it's not really ugly. Just a little bigger than it needs to be.)

It works guaranteed out of the box. No problems. Not as small or fancy looking as the Nokia ones but at least it works unlike the Nokia ones, lol.
[Nexus 4 Accessories] shogunmark:
I got the Nokia because it kinda works... mainly i just wanted to hack up some hardware. i was bored :D
[Nexus 4 Accessories] ztmike:
Is there ANY wireless chargers that work for our phone that stands up the phone, so its easily readable beside my bed so I can use the "Daydream" feature and actually be able to see the screen?

Damn Google and taking their sweet ass time with the orb.
[Nexus 4 Accessories] kms108:
Try searching for sanwa, there is a rebadged version by maxell.
[Nexus 4 Accessories] ztmike:
You have a link? Pita searching on my phone
[Nexus 4 Accessories] kms108:
Just google it.
[Nexus 4 Accessories] KewlRobD:
Unfortunately doesn't look like I can purchase this is the US and can't find anything on a Maxellor variant. I wish we would see more of these international products showing up over here. We could use some competition in the QI charger market.
[Nexus 4 Accessories] kms108:
you can try service like www.shoppingmalljapan.com
[Nexus 4 Accessories] KewlRobD:
Never used one of those sites before but they want me to deposit money with them before I can fully setup an account. I don't know if I trust the situation.
[Nexus 4 Accessories] kms108:
thats a well known site, there are many others, but they are slightly expensive, so read through all the details.

i have used them for a few years now.
[Nexus 4 Accessories] ertw96:
Can confirm that if the phone is raised by a couple of mm, it works without getting the discharging effect. With no case it still charges, but will get the discharging effect every 5 minutes or so.
[Nexus 4 Accessories] KewlRobD:
Thanks guys, I used that service to buy the sanwa vertical charger. I ended up buying it at yahoo auction for $30 plus $8 fee. Just waiting to find out how much for shipping. I will post a review once I receive it.
[Nexus 4 Accessories] the orange bandit:
How many mm? I tested this with the S-Line TPU case on my phone, and made a little raiser out of electric tape that's about 2mm thick. Left the phone on the stand overnight and went from 49% to only 62% - definitely not what I would call acceptable.

I DID get the NFC working, though, which is nice. I'd love to keep this, as I prefer the stand form factor to the pad, but if it won't charge the phone reliably, it's a fail.
[Nexus 4 Accessories] johhnyred23:
You exactly right I bought on Craig for 35,and I thought I lye a zagg microfiber cloth on it,works fine
[Nexus 4 Accessories] harsubs:
I've been testing this charger for a few days now and if there is a gap at the bottom, there is no discharging and the phone charges consistently. It's really not that hard to place it such that there is a gap. The charging is slow (very), but I'm happy with it.
[Nexus 4 Accessories] ertw96:
Just over 1mm for me. I have Diztronic Case which I don't use, but it wasn't enough to keep the phone charging. Phone is naked and raised 1mm and it charges overnight from 19% to 100% in less than 8hrs. The wireless charger is much slower than USB but works.
[Nexus 4 Accessories] the orange bandit:
I'll keep testing different positions. I tried without my makeshift 'raiser' last night and got the same results - 6+hrs, only went from 37% to 62%. Definitely not acceptable.

I'm definitely going to get a different pad, just wish there were more stand form factor options.
[Nexus 4 Accessories] harsubs:
I'm monitoring the charging now - it has gone from 50 to 71 in two hours. So, much slower than usb, but not as slow as yours.

Update: It's at 94% 4 hours later. So probably 8 hours for a full charge.
[Nexus 4 Accessories] milk242:
Got the Nokia DT-910 (Stand up one) and I placed a mouse pad between the plate and the phone (wearing a Ringke case) and it charges fine and even activates daydream mode. Can't get the NFC tag to work, I believe the NFC reader on the Nexus 4 is up top and the NFC tag on the charger is at the bottom.

I wonder if the phone has trouble determining which of the three coils in the charger is active. The Droid DNA works on this so I don't see why the Nexus 4 won't.
[Nexus 4 Accessories] KewlRobD:
I was actually wondering if one of those sticky pads they sell for car dashboards would work. Not sure how much thicker they are compared to a mouse pad. If cut down to size it would probably look nice and make the stand up model more secure for the phone.

I think I saw a promo video where the person tapped the phone to the base of the unit prior to placing it in the cradle. I believe that is the way you activate the NFC chip.

---------- Post added at 02:17 PM ---------- Previous post was at 02:11 PM ----------

This is what it says in the manual. Of course this is written for Nokia phones but it does specify you have to tap the NFC areas first.

"You can set your Nokia with Windows Phone to automatically perform an action, for

example, to switch your screen saver to the alarm clock, when you tap it on the Near

Field Communication (NFC) area on the charger.

1 Tap the NFC area of your phone on the NFC area on the charger. The accessories

app opens automatically.

2 Tap Nokia accessories settings, and select the action you want your phone to

perform.

To start the action, tap the NFC area of your phone on the NFC area on the charger."
[Nexus 4 Accessories] milk242:
Thanks I'll try that,

Right now I'm testing how much spacing I need. I'm using BART tickets right now (I think they are about as thick as a playing card, maybe a little thinner) and I'm down to a stack of 5. With a stack of 5, it cycles 3 times, I think this is the charger picking the right coil to use.

I might go to radioshack and try one of those car grip pads you mentioned, I would think it would be about the same thickness to what I'm using right now.
[Nexus 4 Accessories] kms108:
DT 910 only has one coil, the dt900 has three coils.
[Nexus 4 Accessories] milk242:
Oh well, that throws that theory out.

For mine, the thing is so far charging consistently with 4 stack high BART tickets.
[Nexus 4 Accessories] kms108:
The nfc will only work with the nokia's, NFC tags will only work with the program it was programed with, so the NFC will work with 820 and 920, you can use a certain app's to fully erase the tag and reprogram it, unless the tag is write protected lock.
[Nexus 4 Accessories] the orange bandit:
The NFC works great - you have to tap the bottom of the phone to the stand, not the top like you would on the Lumia 920. I was able to use AnyTAG NFC Launcher to setup a couple of things to happen when I tapped the NFC.

The charging is the bugger - interesting that having that much space between the phone and the stand seems to improve things.
[Nexus 4 Accessories] milk242:
For some reason I can't get NFC to work. Can't even get an NFC reader program to recognize. I hope I don't have a defective NFC module in my phone.
[Nexus 4 Accessories] kcbboy:
I got it to work just fine using Anytag NFC launcher. If you don't have that it will still read it but a bunch of nonsense just pops up.
[Nexus 4 Accessories] milk242:
Got it to work, I was stupidly tapping the bottom of the phone to the base instead of the back of the bottom of the phone.

Is Anytag NFC suppose to launch the task automatically? I have a pop up that appears when I pair and I assume I have to select Anytag for my task to do its thing.
[Nexus 4 Accessories] hansoho:
Charging 6% in 30 minutes is terrible. I have 3 wireless charging pads - one from Panasonic and 2 nameless chargers I got off eBay. Their stated output is 1A and I can easily get 15% in the same duration.
[Nexus 4 Accessories] Azbulldog:
tsntrybo and

I just got one of these DT910s off Amazon for my Droid DNA since it's the only one I have seen that has the phone upright. I haven't been able to monitor how quickly it charges, but I tried out the NFC using the app NFC Task Launcher. The app complains it may not write to the tag, but regardless it seems to work fine. Upon the first touch it had me choose between the default Android NFC tool, which merely displayed some Nokia text string, and NFC Task Launcher. When I selected NFC Task Launcher instead as the default app it ran the proper profile for the tag just as it should have, opening my clock app. Having to hold the phone face up on the base where it can't charge is rather silly, so I think I'll stick with Tasker and its ability to detect wireless charging.
[Nexus 4 Accessories] the orange bandit:
You don't have to leave it on there, just tap it once. The Lumia 920 is the same way. Just setting the phone on the stand doesn't activate the NFC, you have to tap it, then set it to charge.
[Nexus 4 Accessories] KewlRobD:
Did you try the sticky pad yet? I bought one of those energizer chargers and found they the glass back of the nexus 4 causes it to slide around. I originally had the idea for the sticky pad to combat that issue. I bought this pad which I received yesterday. The phone has no problem charging with that in between them. I am getting around 25% an hour. I think the question for you is weather the pad is rock enough.
[Nexus 4 Accessories] hansoho:
I applied a wet screen protector onto the back, no more sliding after that. :)
[Nexus 4 Accessories] serialtoon:
I noticed that after i upgraded to CM 10.1 it stopped disconnecting the wireless charging and it charges without issue anymore. Can this be kernel related?
[Nexus 4 Accessories] Rithina:
Which kernel?

Edited: does not work for me on CM 10.1 Nighty 5 and Franco R28 kernel.
[Nexus 4 Accessories] Azbulldog:
I know, but it's still a silly design to put it there as if you wanted it to activate something while you're charging. If you wanted a NFC hotspot to send a text message or something else only as needed, then I would understand.
[Nexus 4 Accessories] fcng:
Where did you buy the QE-TM101

kms,

Where did you buy your Panasonic Qi charger?
[Nexus 4 Accessories] kms108:
ebay, the seller is from japan.
[Nexus 4 Accessories] hansoho:
Look for seller wwb-jpn. His service is top notch!
[Nexus 4 Accessories] kms108:
I already have it, have to check which seller i got it from.

thanks.
[Nexus 4 Accessories] GrimStranger:
It works for me. It's definitely slower than charging with USB but it works.

82% at 3pm

92% at 4pm
[Nexus 4 Accessories] hansoho:
Wouldn't that take you almost 10 hours for a full charge? :eek:
[Nexus 4 Accessories] KewlRobD:
That's horrible. I get a full charge in under 4 hours using an energizer model.
[Nexus 4 Accessories] paper_kiwi:
:( its sad to know they don't work since they are affordable and come in nice colors
[Nexus 4 Accessories] GrimStranger:
I get varied results of charging efficiency. Sometimes I get a full charge with much less time but I didn't bother to figure that out what is the optimum charging condition.

My Nexus 4 sucks battery like a hungry infant sucking on boobies so it's plugged in whenever possible, like at work. And that's where wireless charging comes in handy. I can pick up the phone, use it, set it back down to charge without the hassle of cable. I consider it an improvement even with the slower charging speed. Plus it's got nice colors :) But to most people I'd say the DT-900 is NOT worth it.
[Nexus 4 Accessories] milk242:
So I've been using the DT-910 for a week now and so far it has charged consistently. It does turn off the charger when the battery is full and it seems like the charger doesn't kick back in automatically until it's below 90%.

I slipped my wife' hair tie around the charging surface and I guess it provides just enough cushion to keep the phone from doing the charging and not charging cycle. The thing also charges at random speeds too, sometimes it fairly fast and sometimes it super slow so not sure what is going on. I did buy a energizer qi compliant battery cover and tested the voltage emitted and it is emitting the standard 5 volts, not sure how to test how much amperage it is passing along. I think I'll next be taking the back of my nexus 4 off and testing the qi coil on back plate but still trying to find my pack of plastic prying tools.
[Nexus 4 Accessories] rockerrock:
Battery Mix is reporting 20% per hour charge. I'm using Daydream mode with Clock Plus with these results.
[Nexus 4 Accessories] Etherfast:
Hi, everyone.

I own the DT900 for a couple of days now, and I've also been experiencing the disconnects from charging the Nexus 4.

I've tried everything that was suggested so far

- various phone positions (and no, the phone did not slip)

- charging with the phone off

- slipping a mousepad/fine cloth over the charger

- repeatedly putting the phone on and off the charger

- leaving it flap for a while (it never stops flapping)

I'm going to root it and Flash CM 10 now, see if it's Firmware/OS related.
[Nexus 4 Accessories] kms108:
I know someone that has tested many qi base, apparently he has mention that the nexus 4 has problems with lots of qi base, it's nothing to do with the nokia, the nexus 4 has been tested to drain too much power from most base, that makes some base will not work or run very hot compared with other phones.

I just got my Nexus 4 with bumper yesterday and picked up the Nokia Fatboy charger from a Verizon store for $45 and it works fine. No flickering like the YouTube videos.
[Nexus 4 Accessories] setzer715:
The device your powering (dock in this case) will only draw the amount of power it needs and/or can utilize. A higher rated AC to DC converter will do nothing. The charger base itself needs to put out more power.
[Nexus 4 Accessories] purnah:
Happy to report that the 4.2.2 update fixes the problem with the Nokia DT-900 charger. I believe it is related to this note in the change log:
[Nexus 4 Accessories] Nospin:
Great find!
[Nexus 4 Accessories] txaggies07:
Anyone else confirm that 4.2.2 fixed the problem? I am using a Nokia Lumia 920 now and have two charger pads. One of them I modified into a sweet car dock. I want to switch, but don't want to lose my charging plates.
[Nexus 4 Accessories] americasteam:
Yeah, it works now. You have to place the bottom of the phone about 1/8" up on the plate for it to charge. It will cycle about 3 or 4 times and then stay charging. Can't just place it anywhere on the plate like the Lumia 920.
[Nexus 4 Accessories] txaggies07:
I thought that was how it worked under 4.2.1?
[Nexus 4 Accessories] americasteam:
Not on my unit. It would never actually charge the device. Would continually cycle. I tried every way in the world to get it to work, but it wouldn't.

Now it will only cycle 3 or 4 times and then charge the device fully. It has to be placed more up on the plate due to the location of the induction coil in the Nexus 4. Its just below center of the device.

I've charged my Nexus 4 the last 3 times with the Nokia plate. It has fully charged each time. Its still more finicky than the Lumia, but at least it does work now.
[Nexus 4 Accessories] txaggies07:
thanks for the info. How long does it take for a full charge?
[Nexus 4 Accessories] americasteam:
I haven't timed it, but it seems about the same as the Lumia. I have the official charging orb being delivered on Monday. If I decide to keep the Nexus over the Lumia, the charging plate will be going to the office and the orb sitting bedside.
[Nexus 4 Accessories] superdx:
I went to a Nokia store to give it a try after the 4.2.2 update and after about 10 mins of re-positioning, I gave up trying to get it to work. It seems to just constantly cycle between charging and not charging. Was ready to plunk down some cash too, bummer. It's too bad, the Nokia charger looks very nice!
[Nexus 4 Accessories] DouglasK:
I have the pad style charger from Nokia. It works ok, but with a twist.

It only works well IF i have the TPU case on my Nexus 4. Without the TPU case, it doesn't work well at all. Totally weird, but it seems to work reliably with the TPU case on, and not work with it off. YMMV, but it works for me.

Also, It works best with the screen off.
[Nexus 4 Accessories] Avarell_Dalton:
Sv: Nokia wireless charging works.

I've noticed the same thing. And also irrational behaviour as stopped charging at different levels 85 and 95 %. Had to return the charger.

[Nexus 4 Accessories] dark_sat:
I bought the DT-900 and although it seems to charge after some position adjustments, it never charges 100% (the led on the plane never turns off). I think there is a issue here, on the phone or on the plate.
