Do we have a list of buy and do not buy QI recievers?

On the Do no buy list is would like this:

http://www.aliexpress.com/snapshot/6421987041.html?orderId=65235835815186

I get 120ma on that.

Highest i recorded was 135ma on my wife's phone, 128ma is the best 1 have done on mine.

Also on the do not buy list is from info DrunkFuX666 gave me

http://www.ebay.com/itm/321620281477

"Not recommend it, because more often it did Not give a steady charge at that level and was too unreliable...

I would say 2 nights every week I would wake up to a uncharged phone... "

So any others we can add to the buy or do not buy list?
[ONE General] zacb:
Thanks for the information everyone, just read every post and picture on this thread. Can anyone who did this let me know if the coil they used (and the name of it) worked long term and just not for a one night test? Don't want to have to buy several types of coils if others have already done it :).

Edit: im not experienced on Soldering, but I'm I'm not too scared of damaging my OPO, are you guys doing a tin Solder?

Thanks guys
[ONE General] LoganMcClay:
Hi zacb,

I do charge my OPO every night on my nightstand with Qi, and my coil hasn't died yet :P
[ONE General] burnski:
I tested with both LG WCP-300 & LG WCP-400 chargers, but with 2A power bricks. My Nexus 4 charges at 950mA on either of them.

DO NOT BUY. They were all either DOA, or charge @ 150mA

http://www.ebay.ca/itm/291230405199

BUY

http://www.ebay.ca/itm/131132062361 . Its finicky for placement but easily charges at 500-900mA

Also, unverified, but its from a reputable established Qi company so if you dont mind spending a few bucks more its likely a winner: http://www.tylt.com/vu-mate/
[ONE General] zacb:
Could i use any Qi receiver? all the ones i see on amazon that don't take a 25+business days to ship are made for galaxy phones. Am I able to take it apart and arrange it how i went, soldering the wires i find inside of it?

Edit: they also have iPhone ones i could use, not sure how those are wired under the plastic though.

Edit #2: just ordered all the parts costing over $100 :( (Charging pad, cheap solder gun. Don't have any of this at the college I'm living at right now)
[ONE General] zacb:
After giving it a solid shot, my phone will no longer charge via usb cable (or wirelessly that was just a mess) Does anyone know if they have any replacement parts for that online or should i just attempt to get a replacement from OnePlus? Any suggestions? Weird thing is when i turn it off it shows it's charging (just keeps vibrating every 10seconds as though i just connected it) but it isn't actually.
[ONE General] hidroela:
can you explain what you did.?

i am about to do this mod and you scare now the **** out of me.
[ONE General] zacb:
I think my problem was i got solder stuck in-between the pins, and I can't get it out. Or i may have melted the pin connectors a bit, not sure honestly.

I'm now realizing how painfully slow my backup galaxy s3 phone is, so much lag and don't even get me started on it's battery life haha
[ONE General] hidroela:
sorry to hear that.
[ONE General] zacb:
All part of the experience, already searching around for new phones coming out incase this doesn't get covered by warranty :p

My suggestion is unless you have proper equipment and you trust your ability of what you're doing, don't do it. If you do trust it, keep in mind the risk-reward
[ONE General] vantt1:
Heh, looks like you beat that other guy from that random useless thread on OnePlus forums. +1

thanks for the details instructions. got it working perfectly.:good:
[ONE General] NWKENT:
WooHoo..wireless charging on both my 1+1's..but no soldering, no mods..just purchased OEM back shells without the NFC coils..installed charging module, trimmed the back shell abit to allow for the USB plugin..and done..my TYLT's and PowerBot's work great, even with a case..My Air Dock 1st Gen. doesn't work with the 1+1, even without a case..I hope the Air Dock 2nd Gen. will..

I also designed enuff slack in the module ribbon, where I can unplug & replug the module in the USB/Charge port without removing the back shell..

[ONE General] inaudible101:
Why in the world would you not just put it behind the case if you are going to use a case anyways...
[ONE General] NWKENT:
Clear back case with dbrand Mahagony skin on one of the devices, and haven't decided, yet on the other device, but for now I have a OnePlus clear case on the other..

Oh..and that would put the NFC coil between the module and battery..wouldn't be efficient..Or wouldn't work at all, as I discovered..

[ONE General] otonieru:
This is my current setup,

Only manage to get around 475mA rate, since the receiver itself rated at 500mA

Will try to upgrade to 1A one once it arrived,

And, i'm not doing any soldering anyway,

My receiver has a hole on it's circuit line, so i can put the cable through it and wrap it around neatly,

As for connecting to the usb plug, my cable is thick yet slim enough to go slip between the first & second pins (as well as sixth and seven) and pushed through the behind part of the plug,

Just placed it properly & neatly,

And you are good to go,
[ONE General] luigirenna:
Help

I've read everything you've written.

One thing I did not understand.

You said without using the soldering iron.

I could explain how you did it.:confused:

A picture would be the ultimate.

Thank you
[ONE General] jgrinst1:
I did the mod this way and it works fine except it's a bit dodgy when my case is on. My trusty Nexus 4 orb charger seems to work with that, though, so I'm happy.

I originally tried to do this with Radio shack 22 gauge hookup wire. Much too thick - don't use this. I eventually cut up an old USB cable and used the wires from it. The circuit board from the S5 also has power output on the right hand side, so I used those terminals. Perfect!

Good job! Thanks a bunch.
[ONE General] 4nth0ny:
Were you able to keep NFC in your setup? If so did it require any modifications to the NFC chip or did you just install the wireless charger and everything was good to go as is? Thanks.

[ONE General] jgrinst1:
Yes, the LG pad is a wireless charging coil AND NFC coil in one, so the NFC points on the pad fit over the OPO's NFC receive points. You have to buy a new back cover without the NFC pad, and that's that. NFC works just fine.

Oh, when swapping the volume control from the old cover to the new one, it only goes in one way. If you have it upside down, it won't work... I found that out. :o
[ONE General] burnski:
So I decided to upgrade my existing internal Qi mod to restore NFC. I picked up the nfc/qi combo for a LG g3. Here's the final install. Works great, nfc works like stock, qi charges at ~900mA, no bulge.
[ONE General] usmave:
what is that little board with the wires? part of the g3?

where did you get the coil and board from?

still using a standard qi pad just receiving about 500 mah.

month ago i tried replacing it with a coil from the nexus 5 backcover, but the little circuit board was build in the device. so couldnt use it with the opo
[ONE General] burnski:
Board is from a 1000mA internal galaxy $4 qi card. I just separated it from the coil.
[ONE General] usmave:
is that board within the device or in the backcover?

wondering where to get it from without buying a smashed s4.
[ONE General] burnski:
no - its from one of these: http://www.ebay.ca/itm/331536120289

Originally I used just the PCB & coil in this Qi card. Here is my original setup:

Then I removed the original small coil, and cut down the PCB. It is approx this part of the coil. The rest of the PCB is just blank and can be disgarded:

Then I replaced it with the LG G3 NFC/Qi combo coil: http://www.ebay.ca/itm/261756381973

I trimmed the LG G3 PCB so that the NFC contacts line up with the pogo pins from the OPO.

Here is last night's charge. I use an LG WCP-300 Qi puck. I consistently get around 850-900mA charge rate:
[ONE General] burnski:
Also for anyone curious about having enough space under the back cover. I didnt want to modify my original black cover so I ordered the white from ebay. It was really tight. I then got the bamboo, and after removing the NFC coil, and a sticker from the inside, and sanding down the injection markings, it now fits perfect with zero bump:
[ONE General] skender85:
Hello Guys

I think that makes a good first post for me... I tried it too, but it did not work. I think the problem was my poor soldering job, so please don't laugh :o

I used wires from a usb cable.
[ONE General] aboveliquidice:
Looking at your pics, it looks like you have the red line connected to the ground pin. Also, you've grounded it to the frame of the micro USB plug. Use a solder wick / vacuum to remove as much solder as possible, and the. Verify which line you've connected as 5v+ To the PCB. The furthest right pin is hot (5v+) and should be red. Always use black for ground.

I wouldn't scrap the project though... This can fixed

[MENTION=5164035]burnski[/MENTION]

do i need the lg part or can i only use the s4 coil ?

What's the advantage , i normally don't use nfc and load my device over night (6-8)h
[ONE General] burnski:
If you don't need nfc you can skip the lg coil and just keep the $4 coil attached to the pcb.
[ONE General] moritz31:

Yup same as the one I used.

[MENTION=5288212]moritz31[/MENTION]: I modded the OPO of my wife today with this receiver: http://www.amazon.de/gp/product/B00OH12LA0?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

I have the ikea charging "wood" :p and also cant get it charge fast. it only charges ~3%/h so i decided to remove the receiver for now.

Have you also used the LG G3 antenna combi like [MENTION=5164035]burnski[/MENTION] ?

has anyone tried the ikea nordmärke?

http://www.ikea.com/at/de/catalog/products/50308318/

thx popy
[ONE General] moritz31:
i've used the s4 one only described here often, sometimes i get around 1000mA but only for a short period and a lot of time i get only around 90 mA, ordered the lg g3 combo but it takes a while to ship to germany :(

playing around with positioning at the moment maybe that helps a bit
[ONE General] popy2006:
Thx, please keep us updated about the lg g3 combo.

pOpY
[ONE General] moritz31:
yeah i will, i also maybe try if i can put the coil into the back cover so that it's not on the battery, maybe a bit better connection and a little cooler battery ?

----------

okay very strange tonight i placed my phone on the charger and it start charging with 400-500mAh, when i woke up this morning it only charged with 100mA.

In the history i can see that it charged with 400mAh for a half hour and the fall back to 100 mAh, can anybody explain that for me ? it's quite strange
[ONE General] popy2006:

Hey [MENTION=5164035]burnski[/MENTION] [MENTION=5288212]moritz31[/MENTION].

I have received the S4 receiver.

The pcb looks exactly the same as on burnskis pictures.

But the label says 600mA.

Can you confirm that was also the same on your receivers?

(which now charges with 900mA)

I don't want to cut the pcb off when I am not sure it is the same [emoji12]

[MENTION=5164035]burnski[/MENTION]: Could you please also confirm that your latest mod works reliable and stable (with a charging current of 900mA)?

Here are some pictures :

Popy
[ONE General] moritz31:
i think it's the same, its the one i use, with that i also reached sometimes around 900mA but it's not very stable and often only charge with around 90mA, hopefully the new coil will come soon

Looks the same. Yes mine also said 600

OK, now i have modded the OPO but just get slightly better charging results :( ~5%/h.

Have used the same components like [MENTION=5164035]burnski[/MENTION] so that could not be the problem.

Maybe my charging station is the issue?

I have bougth the ikea nordmärke: http://www.ikea.com/at/de/catalog/products/80289832/

Anybody have this charger and can says that it can supply 1A current (5W @ 5V)?

Any hints about the charger? Which one is good?

Here are pictures of my mod: https://drive.google.com/folderview?id=0B4JpRMZvEb3sbS04cjdiQWo2ZEU&usp=sharing

Thank you

pOpY
[ONE General] popy2006:
OK guys, i gave up on this.

I can not get a decent charge rate with the components i built into the OPO.

Ill get 2-4% per hour. On my LG G4 ill get 30-40% per hour.

It also gets very hot during charging! Ill think its not good for the hardware/battery.

Also sometimes it just stops the charging process at all.

-> The mod is not usable at all :( at least for the OPO of my wife.

Maybe the OPO cant handle the "small" charging current!?

My experience with the OPO and wall/car chargers is -> you must have an 2A charger.

Otherwise it gets hot and doesnt charge.

In the past i had cheap chargers (car and wall, also from previous phones) which was able to deliver ~500mA, 700mA (HTC).

After you try to charge with those chargers -> it gets very hot and doesnt charge at all.

If you now try the original charger -> it doesnt charge anymore.

You have to reboot and began the charging process with the original (or a strong enougth) charger -> it charges normal and very fast.

So after ill notice this a year ago i have buyed 2A chargers (from Anker) for car and home and we didnt face the issues anymore.

My conclusion is -> the Qi mod cant deliver the needed current for the OPO of my Wife.

Maybe also i have a "monday" device with the described issue!? Anybody else noticed this?

Bad :(:( because Qi would be a nice addon for the OPO.

[ONE General] HL Design:
Hey guys. I did this mod today and checked on 2 different chargers. On my Nokia stand wireless charger it didnt work and on my ikea lamp with wireless charging it works but only if I have the back cover off. I also removed the NFC from the back cover and still nothing. Anyone else had this problem?
[ONE General] popy2006:
Please read my previous posts.

My issue sounds as yours -> the Qi mod doesnt deliver enougth current for the OPO to charge correctly.

I have removed the mod from the OPO.

On my ikea charge the LG G4 works without any problem.

pOpY
[ONE General] HL Design:
Ok well I figured it out. I had removed one of the 'covers'/stickers of the Qi receiver to access the board to connect the cables. I didn't put it back because I didn't think I needed it. Turns out there is a thin black pad on the sticker that I guess is conductive? Adding it back on made it work! It is slow to charge on my nokia stand as my qi receiver is only rated at 600mah but it works!
[ONE General] popy2006:
Nice that you figured it out.

It also worked for me but at ~5%/h -> so it takes ~20h to charge it full, which is not acceptable!

My LG G4 charges in about 30%-40%/h.

Good luck

[ONE General] chenrp:
the issue with wireless charging is heat! and heat is the 1st enemy of your batteries...

I love wireless charging and use it on my Nokia phones and even have a wireless charger imbedded into my table so that when I put my phone on it they charge without even touching the charger.

Remembering what my soldering was like in school stops me from even thinking about doing this to my phone though.
[ONE General] haet:
Awesome work!

Is there a lot of heat generated? The way I see it is a slower charge for overnight isn't too bad to deal with. This is looking like an option as I really like the idea of wireless charging.
[ONE General] Hilbe:
Since the outer pins are the ones shorted together, do you think we could expose the wires and electrical tape it to the pins? Trying to think of a ninja install method.
[ONE General] Ok_Kaleidoscope5109:

[ONE General] lapocompris:
[MENTION=3378372]inaudible101[/MENTION],

I looked at your posted pictures which show only the results. I suppose in order to do it, one needs to follow ifixit teardown up to step 15 ?
[ONE General] inaudible101:
All you have to do is pop the back off. Take out the four screws on the bottom section below the battery. Then pop out the little rubber plugs in the same area and take out the two screws that are under them. The bottom then pops off. I think it's held on with a few clips but no screws after you remove the six.
[ONE General] lapocompris:
Thanks,

I also notice that you cut the backplate, does this mean that the coil didn't fit between the backplate and the battery or you wanted to have the coil near the charger ?
[ONE General] :
You reckon they can afford 610 spec'd inspectors? Hahahaha! :D
[ONE General] inaudible101:
If you review the gallery I clearly explain how it fits inside just fine.
[ONE General] Zmartphone:
Where did he cut the backplate? I couldn't find anywhere saying or showing he cut the backplate.
[ONE General] inaudible101:
I did end up cutting the back plate and running the wires to the outside because the NFC antenna seems to cause a lot of interference. Once the replacement backs were announced was when I did the cut.
[ONE General] Zmartphone:
Doesn't this affect the preformance of the NFC antenna then, when it's beind the wireless charger coil?
[ONE General] inaudible101:
It might. I have no use for NFC currently. It may provide less interference than the NFC antenna did though. It is considerably smaller.

I decided to give this a shot and see how my results were. Since I don't ever use NFC I removed the receiver from the back cover and my Qi receiver works much better through the back now. Thanks for posting your results! Wireless charging really completes this phone for me!

this is what i was thinking too.. not confident in my soldering but i think i can figure out some tape.... are you going to try it? I was going to try it on the one I got but I'm going to buy it for my mom but im going to college so I wouldnt be able to try it until thanksgiving break :(

---------- Post added at 02:59 AM ---------- Previous post was at 02:53 AM ----------

I think i bought the same exact one lol....idk about urs but mine turned out to be only 500 mA :( i wish I had checked out the ratings before i got 3 of those lmao

---------- Post added at 03:05 AM ---------- Previous post was at 02:59 AM ----------

not trying to derail the thread but i have an s4 right now which im using the usb port for the wireless charging adapter. I saw ur blog post with the foils, Is it possible to just connect the two wires directly to the wireless charging port connectors? I have the same reciever as the guy I quoted above. do we have to use the foil to reroute it? I don't use NFC anyway (I might later in the future, does it affect it much?) If you have a thread for this in the s4 section please link it to me :)
[ONE General] inaudible101:
Sorry your post is old, but for some reason I never noticed it so hopefully you get a notification that I responded. You could connect the wires to the two ports at the top left of the phone right next to the flash. You'll just need to make sure you get the + and - correct. You can buy ones specifically designed for the s4 that connect to those ports with little pads. They work really well and require no soldering.

As for Flymods, I have a few of those inductive receivers, but they only put out 500mA. I was able to find a receiver designed for the d5 that is rated for 1 amp and when I tested it it actually put out over 1.2 amps. I ended up also removing the nfc antenna from the back case and putting the receiver under it. I don't have anything to test the NFC on with though except for another phone and it does seem to block the NFC antenna (or I damaged it). You can view my gallery here http://imgur.com/a/63Aj7 of how I have it currently set up. I also ended up shorting the two left and two right pins and have not experience any problems with doing so. With the new 1 amp receiver it charges at a very reasonable rate too.
