Has anyone found the wireless charging accessories for this guy yet?
it's supposed to use the new wireless charging 'standard' so any pad with the same technology should work
e.g. from amazon, type in qi charger

Verizon sells the Wireless Charging Battery Cover.
I tried to paste the link but the Forum won't let me (not till after 8 posts anyways)...
Looks like the back cover is out of stock on Verizonwireless.com. Does anyone know or have heard of this cover working with a Palm Pre Touchstone? Thanks...
Well I got my wireless charging pad and back cover today. The back cover is twice as thick as the stock cover. I came from a Palm Pre so I have a bunch of touchstones. Unforunately, I can confirm that the revo wireless charing system is NOT compatible with the touchstone. The verizon charging pad seems to sense when the phone is near and turns on. The touchstone did not, so that is probably one of the problems. I measured the voltage from the back of the touchstone cover and it wasaround 5.1 Volts. I am hoping I can use the touchstone coil on the stock cover of my revo and wire the charging leads to the revo. The revo has 4 pins for charging but the touchstone only has two, so I need to find out how to wire this. i may have to go through the USB 5V connection. I love my touchstone car mount and I am really hoping to be able to use the touchstones for charging the Revo.

Also, gsxrpilot would you say the wireless charging it worth it? for the almost 100 bucks you spend on it? and does gsxrpilot mean you ride a gsxr street bike?
Well there is a deal this month where you get the back free with the pad, so $70 for both. I got a little more discount because I complained that the only reason I needed a new phone and wireless charger is because my Palm Pre stopped working. I would say that it is worth the convenience. Constantly plugging in the micro usb charger due to the low battery life gets old. Now if I can get my touchstones to work, it will really be worth it.
And yes I have a '92 GSXR-750 and love to fly RC Planes and Helis, hence gsxrpilot.

I might have to get that then. Also, that's sick. My neighbor has a 20xx dsxr 750. They are a blast to ride.
Couple of gripes about this...
I bought the Wireless charging back for my Revo and it's not compatible with the Powermat that I already have, apparently the "qi" technology works differently than the induction that the Powermat uses. It IS compatible with the Energizer power mat which uses the same "qi" technology. but you're looking at the same price for either charging base.
Secondly, the wireless charging cover is twice as thick as the stock cover so any skins or cases you want to get for the phone will not fit. My silicon cover almost fits but buldges out on the sides.
I still think wireless charging is the way to go, just a heads up for those of you who are looking into this.
Well I got my touchstone to work with my Revo! I scraped the charging coil from the back of a palm pre cover (bought 2 for less than $5), then hot glued it on the back of my stock revo cover. I had to dremel 4 holes where the metal disks were and added 2 disks per hole since the revo is heavier than the pre and more disks help it stay on the touchstone better. I now have 4 little bumps on the back of my cover. I searched everywhere for the connector that would fit in the stock cover but couldn't find it. So I wound up using magnet wire and soldering directly to the charging tabs on the coil and the top of the connectors on the phone. Didn't have to use too much solder so I could remove the wires if I wanted to go back to the verizon charger. It is nice having the stock cover back, the verizon wireless cover was so much thicker.

Any way you could post a picture? I'm interested to see if that setup would work for my powermat.
OK,I think I attached the picture correctly. I did the following:
1. Remove the charging sticker and assembly from the back of the Palm Pre charging cover. Do not use the Pixi charging cover assembly, there is a ribbon in it that cannot be re-assembled after removal.
2. I took my dremel tool and routed some space off the inside back of the cover. The revolution cover is a bit thicker than the pre cover and I was concerned it might be too thick to allow the inductive power through.
3. I also routed some indentations in the back of the cover. (see Phone Back Image) I'm not sure if this was necessary either but I had really hoped I could mount the phone vertically on the touchstone in my car like the pre so i put a second set of metal disks behind the indentations. As it turned out, the revo is much heavier than the pre so this didn't work.
4. I glued the sticker and assembly to the back of the stock cover. First I tried crazy glue which didn't work that well so I wound up using hot glue.
5. Finally I soldered magnet wire from the palm charging tabs to the wireless charging tabs. Top tab to the top charging post (there are 4 of these posts, I only used two) and bottom to bottom. The top tab and post is ground, the bottom tab and post are +5V. (see Phone Inside 2 image)
6. I snapped the cover on (there is still a small gap which I haven't quite worked out yet but it works ok). Stick it on the touchstone and it says "wireless Charging" (which is actually annoying and I thought I had figured a way to remove this notification but it came back)
Now all of my touchstones work for charging and I am not sure I will ever go back to the verizon wireless charger.

awesome stuff, I will definitely give this a shot and post results.

nice hack.....looks like your method could work on most any accessory case
how long would it take to charge the revo?
Charging probably takes slightly longer than through the USB port. The phone can get a little warm too but I have never had a problem. It's really convenient in the car where I glued the touchstone to my center console. If you have ever tried to drive while plugging in the tiny usb cable you will know what I am speaking about.
Has any one noticed the 4 pins on the back of the Droid 3 to the left of the battery? Is this just a standard USB port or is it some direct access to the flash/cpu for debugging (similar to JTAG)?
If it is a USB port, is it different than the side connector? (Different USB enumeration or device id information?)
Could this help in getting the almighty root on this device? (or unlock?)
I believe its for the wireless charging pad and the new cover plugs into it when installed.

purelife82 is correct. Those are contacts for the special inductive charging back cover to attach to for wireless charging.
--Chris
Yes, its the inductive charging contacts. At the first moment I saw that I thought those would be for an NFC antenna, but nah - inductive charging.
Interestingly, on the Canadian D3 (XT860 4G) this area has a rubber cover and no electrical contacts. I haven't tried to lift the rubber, but for now I assume XT860 isn't compatible with the inductive charging cover.

Hi everyone, thought I would share a mod I did to my tablet based off this guy on Youtube:
http://www.youtube.com/watch?v=l6QcSpZHGFs&list=UUOxsHE9Vmxb32X66EUSWkOw&index=1
Note he used a Blackberry 8900 Energizer Qi Cover. I used an Apple Iphone 3G one and removed the coil.
Step 1: CAREFULLY remove the tape and casing around the Qi coil. The plastic comes apart easily. You want to avoid damaging the board and wires when removing the tape securing it to the Iphone case.
Step 2: Remove the nexus 7 cover. It clips off quite easily once you get a grip. I found it easiest to remove the sim slot cover and pry from there, but any opening should do.
Step 3: Place the coil. Note where I placed mine I had to peel back the bronze covering to allow the coil to penetrate the back of the case. Run the wires to the NFC connector. Note the position of the wires in the photo. Be sure to insulate the wires with tape and ensure no crossed points (which shouldnt be an issue anyhow).
Step 4: Remove the Iphone connector and solder the wires to either end of the NFC noting the correct positive and negative positions.
Step 5: Test. Note that it will enter docking mode when initially connected. If the docking notice keeps popping up that means that you do not have it centered and the connection keeps re-establishing. I used the LG Qi pad from Verizon for testing. Just pop the cover back on once done, and voila!
I preferred this to the Palm Pre inductive mod since my Nexus 4 uses the Qi standard. Hope this helps some of you!
You can disable the docking screen/options via 'DayDream' mode being turned off in display settings.

I did that mod too. Used the blackberry 8900 coil. Seems like it will take a while to fully charge the battery once its dead. I'm going to see if I can find a larger coil that can put out a higher voltage.. What is your total time to recharge your Nexus 7..? I finalized the mod today and am just charging my unit for the first time now. But it seems to be getting a low volatage as its still I'm single digits and its been on the charger for an hour or so already..
I'm getting 5 to 9 an hour with the lg charger. I'll post results when my energizer arrives and is tested.
What happens if you charge via the pogo pins (ex. a dock) and charge using a charging mat at the same time? I know this is unlikely, but I'm curious if this could cause damage to the tablet.
Does this work thru a case?

It doesnt work through the thick leather Truss case I have it in, but works through tpu covers.

I've got the poetic flip case. It's a thinner plastic with leather. Think I'm sol? What if I increase the coil size? Will that increase the strength?

It's very simple. This is a great mod for a beginner tinker-er
Sent from my Nexus 7 using xda app-developers app
Yep, very easy to do mod. The energizer seems to charge faster. I am going to have to test more thoroughly, but I am getting ~15% per hour with it thus far.
After more thorough testing my LG charging pad seems to average 9-13% an hour, whereas the energizer seems to only do 7-9 an hour. Decent for overnight charging, but certainly not very fast.
Two questions:
1) What's the total cost to do this. That is both a charging mat and a donor back door.
2) How much current (that's mah not voltage) do these doors provide? I'd assume they all supply 5V since that's the USB standard and most things charge that way nowadays. Do they have ratings on them or is it just the situation that they make a replacement door/back for the xxx device and you have to live with that if you have a xxx?

The cost is that of a qi coil as described in post 1 and any qi mat.

I think the reason people go with the palm setup is that you can find them for dirt cheap. What is the best/cheapest source for qi stuff?
Sent from my Galaxy Nexus using xda premium
I have been able to find the energizer base stations in clearance areas like Wal-Mart, Kmart, Target and sometimes goodwill. Any of the energizer stations are qi compatible. My wife was able to score a double station from goodwill with the BlackBerry coils for 20 bucks ya just gotta look around

I have just noticed that the rubber on my charge port flap is loose from the flap on both long sides but still attached to the ends. I do not know if it is torn from the flap or unstuck. Does anyone else have this problem? I think my phone's water resistant capability has been compromised.
I've also noticed that the flaps for the charger port and the micro sd slot are made with a thinner and probably less durable rubber seal than the headphone and dim card flaps.

I would send it to sony and buy myself a docking station
I've noticed with mine that the use port flap doesn't always close/seal first time as it pushes itself back out. Have to push it in a certain way before it stays closed, is going to go back via my network first as warranty is with them.
Something wrong with the flap either way for both of us
Yes docking station is ur best bet. I try to use my flaps as minimum as I can. Or if u use them a lot leave them open most of the time.

Hi!
First, I'm sorry for English, I'm not professional.
A few days ago I made a working wireless charger for Motorola Droid 4.
What are the benefits?
People says, the original inductive charging cover is not compatible with most of cases.
Who live away from USA, can't use a wireless charger, becouse it is only available (officially) in the US. It is very hard to find on eBay or any other site. Almost impossible.
Very cheap. The original charging cover at US, Verzion is $29.99. (+ shipping, and need a person who ship it to me) It is only a cover, and we still need a charger as well.
So, I found a charging pad with and without receivers. There was a small problem. The receivers are only for Samsung Galaxy S3, S4 and Note. Their connectors aren't compatible with Droid 4, but the charging voltage is OK.
We need to take it to compatible with Droid 4. I looking for a long time, which one can I choose. Fortunately I made the right decision.
I bought that: Qi Inductive Wireless Charging Upgrade Kit for Samsung Galaxy S3
Link here
That is only for $30.10 with EU plug. The package include charging pad, usb cable, 1500mAh charger and S3 compatible receiver, and worldwide free shipping.
The size of receiver unit is compatible with free space of phone. We need some cutting but it isn't horrible.
First, I recommend you try, how fits the module in your phone.
Then mark with a felt.
The electrical connector pins are big, (and incompatible) we need to remove it carefully. I used a rework station with hot air (360°C) but you can use a medium sized soldering iron. I think, about 50-60W of power is enough. It took for about 30 secs per pin.
It is important, you need to place the receiver in such a manner, if you remove the back cover, the S3 and some other text need to be visible! Otherwise it will not work!
You see backside of the phone, and the camera is on top. Removed cover. In the right side, you can see four copper pins. The top row is irrelevant. We need tha bottom row. In the bottom row, on the left tere is the +5 V pin. On the right, there is a Ground pin.
We need to make contact between +5V pin of the phone and the +5V charging pin of the receiver unit.
Place the receiver unit to the phone, and see what size of copper wire you need. The lower pin of receiver unit is the +5V. We need to connect it.
I used a wire,1 mm in diameter. It is lacquered, I cycled down it from an electrical part (coil).
I think, that half millimeter in diameter is enough, but a found that, and it is recommended due to the relative high current (about 1A).
When you use thinner wire, you can easier take the cover to the phone.
So you need to solder wire to receiver's +5V pin. Please use the minimum quantity of soldering wire, becouse if you make a big knot there, you will have not enough place to take cover back.
When it is done, you can see how can you bend (or cut) the wire for best connectivity with phone's 5V pin.
Now you need to solder a wire to ground, like the previovus one, but not sure, that the two wore have enough space, and we can make easily short corcuit.
For this reason, we will use the iron cover of the SD card slot. This is a very good ground point.
So, one cable will go down, other is go up. They can fit and the soldering is more easy.
PLEASE BE CAREFUL! I recommend, before you make any electrical or hot operating you need to put an aluminium foil or an iron plate to top of the battery. I think to taking out battery and then in, is not easily possible, becouse after soldering there are the receiver. The battery can damage and explosive! The plastic parts of pohone can tolerate the heat for sort time! If you can not solder succesfuly, you need to wait while the parts cooling down! I recommend, use flux and/or high quality of soldering tin. Take out the SD Card! Please don't make short circuit!
It is not too difficult, but you need to be careful and attentive.
When the soldering done, you can try the charger.
Before you can take cover to phone, you need to cut the lower center of receiver. (you can see on the cover, exactly where. There are a claw and on the phone there ara a hole) Important! We need all of holes on phone, so the wires must not hang in to holes.
I cut the piece of receiver unit from lower left side, at the speaker.
Thats all. We are done. I think it longer to read than make :cyclops:
I made some pictures, I will mark these and upload in short time.
I'm going to measure the charging time with:
1,5A USB charger (direct cable)
1,5A USB charger with wireless charging pad
1,5A USB charger with wireless charging pad (phone in a 1 mm thickness of Trident case)
0,5A standard laptop USB (direct cable)
0,5A standard laptop USB with wireless charging pad
0,5A standard laptop USB with wireless charging pad (phone in a 1 mm thickness of Trident case)
I use that from 3 days ago. It works correctly. By the factory, the charging current is 1000mA with the 1,5A charger. About 66% of efficiency.
The USB charger's stand by consumption is 0,4W.
When the charging pad is connected and it is in stand by mode, the consumption is 0,98W
I'm going to bring images, and refresh the post, but here (Hungary, GMT +1) the time is am 2:31.
Good luck guys!

That great way to charge the phone. i know that my usb plugin is getting a little wore out.......glad to know that there another way to charge up the phone in case of emergency. Congrats.
Hi,
thanks, it works for me
My IQ receiver was a bit higher, or the battery, so I had troubles to fit it in. My solution was to cut every superfluous piece and pull the uper layer of slide away. Additionally, I put it a bit nearer to the camera, The last thing was to horizontally cut the gold contacts and solder the wire directly on them.
During charging, the usb charger+pad+droid 4 use 7W, without the droid 4 the pad+charger draw 0,4W, both measured at the primary side ot the charger.
Best regards,
mifritscher
Thanks for the info, looks promising I love your using Micro SD casing as GND
BTW the pad + receiver can be found at eBay for as low as US $12 Gonna try out for myself soon.
Did you get to measure the charge times?

Charging times are about equivalent
Different approach, same result
Hi, thanx 4 the great idea.
I took a different approach to install the charging pad. I felt not comfortable to solder directly to the phone, so I used copper-tape, capton-tape and some short wires I took from old headphones to mod the pad directly into the back cover of my phone. it got a little bit bumpier (half a mm), but it charges perfectly.
I applied some solder to the ends which connect to the pins, so the copper wont oxidize and the connection has more pressure.

That's a nice solution, and pretty much how the "real thing" was probably set up. I noticed that the back has an internal indentation where the pins are to accommodate the connector, and I had experimented with how I might fit a charging pad in there (actually, it was the connectors that I saw as the biggest challenge), but didn't manage to get anything that I thought was robust enough (I was using cut down parts of a SIM card for the pins to make contact with - you look to have done a better job with the copper tape.
I'm really surprised that we can't buy a new back with all of this gubbins already installed - perhaps you should manufacture a few?
mugen 3800mAh inductive charging cover required!!!
i'm tempted to try this myself. the droid4 keeps getting better.
i just experimented with cardboard, seems to have plenty of room between the cover and the battery. i definitely need inductive charging.
Update 2016
@zuloo.de
Hi! I copied your method for wireless charging but I was too lazy for soldering. That is why I used only copper tape. I ordered under 5$ charging pad and receiver for Galaxy S3 (cheap from China) and it is working good. My receiver says that it can output only 0.8A so I guess it is little bit slow. Can you tell your feelings about the heat? I think that my Droid 4 is pretty hot but I never used wireless charging on other phones so I don't know if it is normal. But thanks anyway posting your method :good:
Here is pictures. I tried to take picture about the bump. It is not bad but you can feel it.
