[How-To] Moto G wireless charging (Universal Qi Receiver)

I've received my universal Qi wireless receiver today. The receiver is smaller than I had thought and fits perfectly into the Moto G. Since our phone lacks internal preparation for Qi (like it can be found on the Samsung Note 2), the connection is made via a micro USB plug. The backdoor can still be clipped on without being disturbed by the Qi receiver pad or its flat band cable. Charging time should be about the about the same as charging the phone from a PC USB port that doesn't output more than 500mA.
This solution is obviously for those who don't need the phones usb port on a daily basis.
The adapter on the left picture (and in the video) is from ebay and is the one that arrived here first. I’ve changed the cable routing to remove the ugly bulge that was visible on my first picture. This adapter outputs a maximum of 500mA and can be purchased from ebay.
Make sure to purchase the "interface layout A, narrow interface up” variant.

17.Jan.2014 - The picture on the right shows an adapter purchased from DealExtreme, that arrived here yesterday. This adapter delivers up to 650mA and the flat band cable comes out of the lower side instead out of the backside which removes the need to bent over the cable.

Both adapters work well, so don't worry if you've already bought the one I've first reviewed. (I have both version in use on different phones)
Here is a small video that shows me placing the receiver inside the Moto G:

Update 13.02.2014
From my testing I can tell the following:
1. An unrooted Moto G needs to be screen locked (I use the pattern lock type) or it will refuse to charge due to the missing pins. You can unlock the screen while it is charging as long as you don't lift it from the qi charger. (tested on 4.3 and 4.4.2, DE and FR firmware)
2. Root in combination with dubidu's tool makes it more straightforward but is not required.

Should you wish to buy an adapter for your Moto G, make sure to get the "narrow-interface up" variant

Nice. Can you tell us where you got it from -- is it just one manufacturer making these?
Cheers.

I just bought it off amazon (hooray rewards card, it was free).

Thanks. I had looked on fleaBay and it looks like they all have the same packaging. I imagine any qi wireless charger thingy should work. In theory.

anyone know if this would work through an otterbox case? or I guess if this would even work with one due to the fact the part that plugs in sticks out a little bit...

I've bought it here:
http://www.ebay.com/itm/261348107126
The auction uses the same pictures as used in the amazon offer posted by JCBomb, might even be the same seller.

This is cool! I just hope there's like another way we can integrate that wireless charger.

Just saw your post at android.hilfe and started looking for some charger, it's indeed a neat solution.

Are u guys using this wireless QI receiver? I'm going to buy one next month, D: . Just for curiosity, how much time do u guys spend to get a full charge with the QI

Guys i found this one at dx.com
http://dx.com/pt/p/micro-usb-qi-wireless-charging-back-clip-black-253066

Those kind of product are not so great are chaging, basically it's almost the same power that if you charge through uSB = 500mA.
What you need to check is the charging value, sometime it's :
- 400mA or less (avoid it, will take ages to charge),
- 500mA (just like your regular USB charger),
- 1000mA (great ones, will charge just like a wall charger, twice as fast as the previous model).
So the one at DX is great, but they're cheaper on ebay, plus you can choose between Black or White - http://cgi.ebay.fr/ws/eBayISAPI.dll...eName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

This one was the cheapest (around £15) I could find and works fine.

wow, so cool :good:

Am I the only one thinking about finding the plug they use with all the pins intact and integrating a micro sd card into it for OTG storage? Wireless charging and storage, all in one, and fitting under a case.

I had that exact thought about two hours ago. Throw NFC in their while your at it.

I had actually started to do some verrrry preliminary research into something like it using a ribbon cable and another usb port, so you could plug the phone into a wall charger and have the usb/sd card piggybacked off the cable. Hadn't gotten very far though...job, kid, wife etc.......
Someone TAKE MY MONEY for it!! Especially since it seems we're all soon to be headed down the 'no sd card' path.

I just got a Moto G for my wife and Nokia Wireless Charging Plate DT900 is not working any ideas why ?

It's not working with one of the universal QI receivers? Have you try enabling the floating charging (see my post)

Hello.
The Moto G doesn't support Qi on its own, you'll need to rig it with an universal wireless Qi charging receiver.
You can buy them from ebay, dealextreme and some other china based stores. The first post contains a short installation video.
This one from dealextreme will work (Output up to 650mA):

Are there any wireless battery packs yet?

The reason that most battery cases suck is they make the phone longer.. but with wireless charging on the nexus 5 we don't need that...
Are there any of those yet?

I believe he's asking about a battery case that utilizes the Qi charging capability instead of having a built-in plug that plugs into the micro USB port of the phone.

That would be really inefficient and expensive if I'm picturing that correctly!
So: Qi receiver in a case > internal case battery > Qi charging plate in case > Qi receiver in phone?
May not be longer, but that would be damn thick!!

Ah… maybe that’s the reason there is no such case then :silly:

At 75% efficiency any external battery is throwing away 25% or more of its stored power, if used wirelessly.

Wireless charging is not really efficiency but far away comfortable and convenience than wires. I already forgot when I last time used cable for charging purpose.

Not to mention the heat generated from wireless charging.

Nokia has one , model DC-50
http://www.nokia.com/global/products/accessory/dc-50/
Its really high quality built and probably has multiple coils as I can place my N5 anywhere on the surface. It also gets charged wirelessly and can be charged and charging your phone at the same time, all wireless, meaning it also has charging receivers at the bottom.
Downside is that it had a rather small battery for such a large device ( can only add about 50% to the N5 ) and it only charges devices wireless, not wired (no USB out) and is expensive. It is a really cool powerbank and its the only one in the market that can be charged wireless.

I like the Anker but have major issue with it. Often when stored in my bag, the charge button gets pressed and it will drain to zero unless stopped. Otherwise its a great charger and functions as a desktop charger when plugged in at my desktop.

[Q] AT&T Note 4 support qi charging?

Hey all,
For those who got their Note 4 early from AT&T did they pull a fast one like the LG G3 and rip out qi charging pins in favor for powermat?
Thanks!

My understanding of qi with the note4 was that it only was available with the optional case, and it's not built into the phone.
Wasn't built into the s5 either.
Sent from my SM-G900A using Tapatalk

Can someone with an att note 4 pop in a qi receiver and see if it charge up? I have a bad feeling they went pma just like the g3.

It's Qi charger. I don't have the adapter yet, but others have pointed out that the contact points on the back match the Qi specifications. I just got my Note 4, and opened the back, and indeed the contacts are identical to my wife's S4

Just because it has the Wireless charging contact pickups, doesn't necessarily mean it will work with Qi. The LG g3 had the same contact pickups, but at&t disabled Qi charging at the hardware level, and made those contacts only work with pma charging receivers.

let say wireless charging works, will it still take advantage of the fast charging feature though?coz I don't think so

NO, wireless charging is a Lot Slower charging than with your USB cable and AC adapter for Fast Charge.

It supports Qi. I bought the official samsung back. I use it with a Qi charger I bought off amazon. Works great but due to bulk, limits my cases.

Wireless charging can be done if you buy a wireless charging battery cover and these have them built in also. A cheaper route is just buying these little wireless recievers and stick them in, you can get them cheaper on ebay (but my work computer can't access Ebay sites).
Wireless charging IS slower than normal charging, its all about convenience. I have a few around the the house and a couple at work. Most output .5 - 1 amp range compared to 2+ amp chargers and the included adaptive fast chargers.
The links are for example only, not telling anyone to buy anything. Hope this helps.

Wireless charging

Hey guys,
Since the OPO has NFC I'm assuming wireless charging will work... What are some good and cheap wireless charging options?
Thanks!

NFC and wireless charging are two completely different things. You could add wireless charging via a universal QI receiver but that's it

Ohh didnt realize that! So would I just need a QI receiver and I can put my phone on it? Or do I need a special case for my phone?

You need a wireless charger receiver, you will lose the USB port, when you want to use USB you will have to take the case off and take the charger plug out.
Since it's pretty thin you can use any case, or none (Maybe not metal cases).
You also need a wireless sender, this is the pad that the phone sits on.
Notes: Since these are only 500ma (have not found a pad > 500) and with less efficiency (so its actually less than 500ma), it will take a very long time to charge the phone. I dont even know if its able to keep up with the power requirements of the phone if it's in use.

Powerbot chargers are supposed to put out 1000mah. I think its partially dependent on the actual charging cord plugged into the qi charger though

that is true. all parts need to be compatible to get a decent charge rate. i had a charger that put out 2amps and a cord that supported it too but most receivers put out 500-750mah which results in a slow charge. and i havent found a decent receiver yet either. Most of them are really finicky and need to have the phone placed just right on the receiver for it to charge.

Car fast charger?

Does anyone have a car charger that works with fast charging? Or any recommendations on one that will work?

If you're looking for wireless I don't think there is anything out there right now. I bought the iottie like a day or 2 before news broke of the speed reduction. They say they are not going to go for certification. I have an email out to Anker's marketing team.

there are tons of type c options out there, personally I'm using the PD charger from choetech. anything rated for either 3a/5v or PD will fast charge. this is the one I'm using:

Here's a couple I would trust

My other posts were about wireless quick charging. I got that on the brain, apparently.

Yes - I use the Iottie One Touch Wireless Charger and it works GREAT for every phone I have used it - including my Pixel Xl 3
It is a little pricey but it is the most versatile charger I have found - and it is very user friendly - for taking the phone in our out of the phone holder/charger.
I also really like the Iottie Discs they include with the charger/holder - it allows you to mount the charger/phone mount on a curved dash without any problems at all - and in a pinch, they can be removed without messing up the dashboard. Great Charger - great Car Phone Mount. Really is the best one I have seen

I've been using the Anker one and works really well. in essence any charger with USB Cand PD certification will do the trick
https://www.ebay.com/itm/USB-C-Car-...blhkm:sc:USPSFirstClass!92143!US!-1:rk:4:pf:0

tried out my choetech 10w wireless car charger. didn't mess with any measurement apps since I knew it wouldn't charge at 10w, but it did charge the phone with navigation running, screen on and music streaming over bt. since it's powered by type c you can always just plug the phone in directly if you need fast charging, but if it outpaces navigation that's generally good enough for me.
https://www.amazon.com/Wireless-Cha...ar+charger&dpPl=1&dpID=41Qp1oKQsTL&ref=plSrch

I've been using a 10w wireless charger in the car and it works with Google Maps navigation and Bluetooth audio running. It doesn't charge fast but not having to deal with magnets is nice. The only issue is that if you turn the car off the arms won't open at the push of the button. Not a big issue because the pho e is easy to take out.
If I do need to fast charge I just place the phone in the crawl then unplug the power from the car charging mount and straight into the phone. I'm using a USB C PD car cigarette lighter socket.

Does it still charge and maintain a charge while using the phone for streaming/nav, etc?
Oh, and will it work if my XL has a bulky case?

I have a question.
See it's nice to have wireless chargers in the car with arms to hold the phone. Even better to have a wireless charger with magnet.
Now I won't go in debate of over charging the phone but is there a wireless charger for a car that has a button to turn ON and OFF the charge? I don't care with or without a magnet to hold the phone.
I drive allot so I don't mind a slow charging the phone, I do care about leaving the phone on without over charging it. Plugging the cord in and out isn't fun.

it does charge while using navigation - and Wireless Android Auto - (which is a pretty big drain on the battery) I don't know about a "Bulky Case" I use the Ringke Crystal Fusion Case" which is fairly thick - and it works fine for me - but I haven't tried any other case, so I can't say for sure.
I love the Iotti One Touch - Wireless - it is an awesome holder/charger
Good Luck

Granted i will have to install or use two side tape to attach two metalic strips onto the phones case to get the magnet stick to it. Should be piece of cake or buy those metallic rings that sell and attach them.
there is also this one, but sadly it doesnt come with a suction cup (which i really need) I does come with a metal ring tho.
