There are you tube and sites showing taking the touchstone receiver out and placing it in the S4- ebay has the kit here http://www.ebay.com/itm/New-Samsung...t=LH_DefaultDomain_0&var=&hash=item7dc538f9ea

My path after a little testing with what i have is to use 3 layers or 2mil steel tape on the phone and magnets in the charger- i will use magnets on the phone as last resort.

I will say the S4 does not like magnets anywhere near the center of the phone- it turns the screen black and places the calendar in large digits at the top. Not sure what mode this is but ti rectifies itself once magnets are removed. This is even with the tape on the phone and magnets used externally. this behavior was not seen on a S2

Again for me- how often do i need a compass or use NFC if they are affected- the benefit of being able to slap a phone in the car on a smooth pad is worth those 2 features if there are affected (I will not be testing NFC)

My chargers and other stuff are on the way but may be another 3 weeks because some is coming from China

---------- Post added at 07:40 AM ---------- Previous post was at 07:00 AM ----------

I should have added my driver is 2 fold

- use Qi instead of proprietary stuff like touchstone

- have a strong charger so it can still charge in the car with screen and GPS on. I looked at the Zen (old style) charger but there are no specs on it. I ordered 5 of the powerQi which are rated at 1.5A and have a 8mm charging distance.
[Galaxy S 4 Accessories] vacaloca:
So here's a question... if the Qi and generic branded ones only need the 2 pins for wireless charging... what are the other 2 pins on the opposite side that connect to an antenna on the OEM cover? I noticed that on the OEM non-wireless charging covers (for both Verizon and US Cellular), those 2 pins rest against what looks to be an integrated antenna on the back cover. The more interesting bit is that the antenna pattern is slightly different as far as I could tell between my VZW one and the USCC one.

What is that antenna for? I thought it might be for NFC, but I thought it was odd that the pattern was different between between phones on different carriers.

Edit 1: FCC document mentions the NFC antenna is integrated in the battery -- https://apps.fcc.gov/eas/GetApplicationAttachment.html?id=1928214 but there is no mention of what those 2 contact points are for.

Edit 2: Aha! It is for NFC: http://www.exportmarkets.com/product/20313/qi-charger-antenna-with-nfc-for-galaxy-s4

Update

All my stuff is in- here is what I have found so far

Charging rate= 20% an hour- this is with an Otterbox commuter case with the steel tape in it (not currently being used) and velcro to stick to the charger at the house. I am going on a mission trip then training for next 2 weeks but will get the car going when i get back and report

I used velcro instead of magnets after much testing the magnets on the steel tape in the phone- I have not given up yet but it is apparent that I would need to embed the magnets into the case of the charger so that they are exposed in order NOT to use magnets in the phone.

Using magnets in the phone works but I am not going to take a chance at it erasing credit cards.

Charger used

Phone Reciever

Velco- clear 5/8" round (these are pretty thin)
[Galaxy S 4 Accessories] sherdog16:
Idea for ya to try. In case you don't want the velcro on your phone. I got some of the double sided sticky tape (non permanent) and stuck it to my receiver. Press it down on the receiver real good and when you set the phone on it it'll grab it lightly and I experienced no transfer of any sticky goo onto my case. I eventually went without it but you may find you like that better than the velcro as there is nothing attached to the phone side of the equation.
[Galaxy S 4 Accessories] Bwanna:
I wonder if this will work with velcro on the phone and this desk charger? Might be able to make a mounting attachment for a motorcycle.

I have found a desk charger I may get - but it's 1A which may be ok since i won't have GPS on at the house :)

Should be no need for velcro with the TYLT- I considered it but will 90 degree mount my phone to the PowerQii for desk use so the microphone is clear.

This weekend I will wire up the car for the mount I am using. I have decided not to use magnets- too much hassle and potential for damage to the credit cards and my S4 is touchy on the magnets. I also decided not to try the double sticky tape- will attract dust etc over time.

Girlfriends pink otterbox commuter would not allow charging but a white otterbox commuter will- I think the pink allows too much space. Also for those with VZW and a Note II, VZW covered the connectors- there is you tube on how to cover them but I tubed it and cracked the LCD ($250 fix) so be careful if you have a VZW Note II
[Galaxy S 4 Accessories] Bwanna:
My thought was more for the jarring that occurs with a motorcycle. Maybe using a pad attached to an inexpensive universal handlebar holder BUT put velcro on the back of the S4 case and on the front of the pad. I imagine a wide patch of velcro would easily hold the phone. The question is will the charging be possible or reduced by the added thickness of the velcro??

Another idea I'm having for my motorcycle is to get a waterproof zipper-type pouch that is thick enough to hold the pad and the phone.

http://www.ebay.com/itm/Bike-Waterp...Holder-for-GPS-Samsung-S4-i9500-/190861206156

I can sticky tape the pad inside the pouch and then drop in the phone and zipper it all up. For a motorcycle this gives the security of it not falling out if you hit a bump.

Thoughts?

[Galaxy S 4 Accessories] delaneybob:
Glad you found it- that receiver is rated at 1A- although the chargers is 1A field coil- it's likely 700 mA to the phone given the distance/stuff in between- it's the best i have found. It took 3 weeks to get here

None, all transmitter has a input upto 2A, but it's the output you're looking for, the max you will find at present is 1A

Here is my car setup- very happy with it

http://youtu.be/I1PXlx-WUDw
[Galaxy S 4 Accessories] swieder711:
Thanks for the video. Very nice setup. I like the hardwired 3A converter and Qi pad. I may order the same items from eBay.

I have the UAG case which looks similar to the Otterbox in your video.

Have you measured the mAh that the phone is getting?

Is there any engine noise getting picked up by the audio or are you using Bluetooth?

I am not thrilled about the Velcro. It does allow some quick to mounting/unmounting the phone. Do you think the Qi pad would fit in an iBolt dock? I wonder if slimmer charging pads will be coming out that might fit better with the iBolt.

Thanks for sharing all your research. It will save us all a lot of time.
[Galaxy S 4 Accessories] demusss:
I like the 3A converter aswell.

Im thinking of taking apart a Qi charger and just putting the coil part on the front of a phone holder im already using and the circuit behind the back.
[Galaxy S 4 Accessories] open1your1eyes0:
Just as a small update for everyone I've decided to scrap all personal modifications and back this project (highly recommend it).

This is and looks better than anything we will ever be able to build on our own (not to mention the amount of time).

Synergy: World's Best Wireless Smartphone Charger

My only question on this one is the amount of current it supplies. I'll be sure to check that when it arrives.
[Galaxy S 4 Accessories] delaneybob:
As far as mAh to the phone- i have not measured as I do not know how to do that- I just bought the largest power rated components I could. What mattered to me was power capability and ease of unmount and mount. I get 20% per hour on the charger with screen off and 5% per hour with GPS on and screen on medium to high brightness

Yeah- I hear ya on the velcro, but it works!. My idea was to use steel tape inside the case and use Ne magnets embedded in the charger. I have 100 feet of steel sign tape and a ton of Ne magnets I tried. Bottom line was I needed magnets inside the phone (I was not willing to risk wiping the wallet credit cards) or embed the magnets in the charger such that the magnets were exposed (was too much a hassle) with the steel tape in the phone case.

I have no idea on the Ibolt dock. I was lucky- I was going to hard mount the setup to the dash via plates that came with my ball/mount I bought on amazon. Then i looked at my old Droid X motorola mount and Viola!- the ball fit. So I chose to use the windshield mount. Other mounts I looked at afterwards DO NOT allow the ball to separate from the rest of the mount
[Galaxy S 4 Accessories] swieder711:
Where can I get the socket that you glued to the back of the charging pad?

You can measure mAh with an applications called Battery Monitor Widget Pro. Its a great app to see what is happening with charging/discharging. You can try the free version here, https://play.google.com/store/apps/details?id=ccc71.bmw&hl=en
[Galaxy S 4 Accessories] kms108:
How about slightly mod of this qi charger.
[Galaxy S 4 Accessories] delaneybob:
Great find-would like to understand the point made at 2:25 in the video. They are using Ne Magnets on the base (originally looked like stick tape) then they say "coupled with special foam"- the magnet has to attract to metal so wondering how they are doing that and still allowing the phone to be in a standard case.

The other note with magnets on S4-> it can make your phone go into a weird mode. Grab a Ne Magnet and go down the left and right side ( i think it's the left) and the phone goes black

[Galaxy S 4 Accessories] swieder711:
I get 1100 to 1200 mAh at home and in the car when charging with the screen off. I typically use GPS and audio playback when traveling. So that is a pretty big hit on the charging rate to go wireless.
[Galaxy S 4 Accessories] delaneybob:
Maybe there is a lag in the reading- not sure but My hit is ~20%- I will leave it on longer and see if it changes- especially at home on the 1.5A charger
[Galaxy S 4 Accessories] swieder711:
There can be a lag in getting an accurate reading. I suggest keeping the Battery app running for a day or two. I use a widget for the app.

Then you can see the rates over time and getter a better sense of the data.
[Galaxy S 4 Accessories] rdrean:
EDIT: Forgot to title it BUT I am referring to the Owl Carpad S3.

[Galaxy S 4 Accessories] swieder711:
I got the following reply fron synergy when asking about how much power the phone will get and how the phone will be connected

Daniel D'Agostino says:

Hi Scott,

The rate will be limited by the phone. Synergy with the latest version of firmware can deliver 10W of power. This is more than what is needed for any cell phone or tablet.

It uses rare earth magnets coupled with micro-suction foam to hold the device. there is a thins receiver module that is placed behind the S4 cover.

Thanks,

Daniel
[Galaxy S 4 Accessories] kms108:
it seem about right, as QI standard requires max of 5W of power.
[Galaxy S 4 Accessories] open1your1eyes0:
Wow 2000mA? That is bigger than I ever thought. As far as I know, almost no wireless receiver accepts more than 850mA (even though some wireless chargers go up to 1000mA). I wonder what made them decide on that high of a current.
[Galaxy S 4 Accessories] kms108:
2000mAh is usually the input current, output for most is 1000mAh for transmitter, but at present no receiver or phone reaches 1000mAh, only the nexus 4 at 997mAh.
[Galaxy S 4 Accessories] open1your1eyes0:
Yeah exactly. This is why I was surprised because the way they worded made it seem like output current. So we still need that information. My guess is standard 1000mA current. As long as not less shouldn't be a problem.
[Galaxy S 4 Accessories] kms108:
for my guessing, the synergy charger, the transmitter unit and receiver modular is a third party product, made in china oem/odm, who know?, it the actual holder that might be designed and made from them, so I think it's;

transmitter (holder) not sure about input, but output is 1000mAh

receiver (phone) will be 650mAh, which is the max for any receiver sold on the market so far.
[Galaxy S 4 Accessories] delaneybob:
Probably future proof. It would be great if they can deliver that without heat issues.

It appears he is using magnets for things like the HTC with a metal case and micro suction foam for things like the S4

[Galaxy S 4 Accessories] Raygray123:
So does this setup charge while the screen is on in the car?
[Galaxy S 4 Accessories] delaneybob:
Not sure if you are asking on what I did or the Synergy

For my setup- charge rate is 20% /hour screen off and 5% per hour with GPS and Screen on. I took measurements on the battery Widget and the only reading i would adjust is the OEM AC charger which was 1.2A vs the 850mAh I stated previously. so yeah it's a big hit- however I can live with it. If something (like Synergy) comes along with more juice and no heat issues, at a decent price point- I would switch.

Hardest part is wiring the car. next car I am doing has all the fuses in the engine compartment (way to go Americans!) so will be a Royal PITA with a Fluke, solder gun,and wire tracing as i do not want to punch thru the firewall and the fuse box itself is poorly laid out and may make the Add a Fuse not feasible.
[Galaxy S 4 Accessories] delaneybob:
I tried the suction tape like Synergy is using ($25 for 8.5x11 incl shipping)- works great without a case- not so well with an otterbox case- likely you need a smooth case to make the adhesion. I am not giving up otterbox protection and will go back to velcro.

You tube http://youtu.be/iZ-r_goEiQ8
[Galaxy S 4 Accessories] swieder711:
Very helpful video. The sticky back will not work for me either since I am using a UAG case. Too bad as it seems like an elegant solution.

I also don't think I would be happy with the charging rate on a Qi pad. I get over 1200 mAH when I plug in my phone to my office or car charger which tops off my battery in a very short amount of time. Maybe in the future the charging rates will get better.

Good luck.

My number 1 reason for wireless charging is because my phone is the audio source for my car, using a USB DAC.

I'm not 100% satisfied with this setup. I have to pull the steering wheel out a little, as the wiper stalk gets in the way, and now blocking the lower-left part of the screen. And the vent the dock is attached to is facing up.
