Induction charging back.

Anyone else think they might get the induction charging back plate when it releases? $39.99
I'm not sure I'm sold on it if it needs to be laying down to charge.

I'm on the fence about this one. I want a charger I can have at work where I can just set my phone down without having to plug it all the time, but I definitely don't want any added bulk either, and it looks from that pic like there's going to be at least a bit of added mass on there.

Well it seems very convenient, but with the current size of it I rather use my extended battery.
It also charges much slower using induction.

It sounds cool but if you take a second to think about it you probably shouldn't. It's less practical than plugging it in. It has to lay on the charging pad so you can't really mess with it while it's working. Maybe you could rig up a stand so you could set it on and watch movies but really, it doesn't seem worth it. I often use my phone while it's plugged in at night and to do so I have to pick it up.

I will have one for home, car, and work. I had the palm pre with inductive charger and it was awesome. Set it on the charger when at your desk and just grab it when you leave... No messing with a cable. Very neat too with no wires laying around.

I would buy one but they are a little pricey (imo) and my case (which I really like) will not fit it.

Do you happen to know how much mA this unit outputs for charging?

Wireless charging mod.

I cannot wait for the official galaxy S3 wireless charging kit to come out.
I got inspired by the Galaxy mod that was done by using parts from a Palm Touchstone cover.
ww.qianqin.de/2011/09/28/high-waf-inductive-charging-mod/
I am pretty sure, that I don't need to do an intrusive operation as the one in the link - I believe that Samsung made pins ready for it under the cover.
Does anyone know what the two 'pins' that are exposed to the left of the battery are for?
Thanks!

There are countless threads regarding the "pins", wireless charging kits, and that mod.

I have a touchstone. And a back, and would like to see if anyone has applied this to the S3 and made it work

I have a feeling the wireless charging module will interact somehow with the two pins next to the battery. I was planning on attempting this mod using these pins but without a multimeter i am unable to tell whether these pins can be used and which way round to wire them up. If anyone can assist i would be grateful.

Yes. Countless threads about the mod for the Galaxy S, but I haven't been able to find anything about pins on the Galaxy SIII.
- Maybe I'm just bad at searching, believe me I have tried!

I also would love to know if and how someone gets their sgs3 working with the palm touchstone! Hope it is not too difficult!

I have finally managed to find a page that claimt that the two pins next to the battery indeed are for wireless charging.
ww.trustedreviews.com/samsung-galaxy-s3_Mobile-Phone_review
Only problem is, I don't know Trusted Reviews - so I don't know how 'Trusted' they are?
All I need now is to find out which pin is 0V and which is +5V. (I'm pretty sure that the current is the same as the Palm cover provides.

Every accessories are always made for on pin, hdmi,wireless kit etc. Always Samsung market tactics.
I wish you'll do it.

Upper pin is plus, lower minus - and it has also be done!

Yes it works, it will be a little slower, im only seeing 450mah going in as opposed to about 1000mah
But that doesnt matter in the slightest as i mostly charge overnight

that is great news! That does not look too difficult and it looks as NFC is not touched. Just the translation is difficult and not knowing what samsung wireless charging is about.
I also wonder how snug the fit is after adding the magnets from the touchstone back cover?

I will post details soon when i am back home

I'm still waiting for my touchstone and palm battery cover to arrive...

I found this! He looks like he did a great job. I am just curious if he had to solder anything to the phone?
http://www.youtube.com/watch?v=uAqP3T_Mbzg

yes he did, i'm gonna try it with just tape - his solder blobs seems to be huge and because of the the cover makes this bulge... maybe then it will fit perfectly
the samsung wireless charger looks nice but i like the idea with the magnets of the touchstone!

please post pictures and a possible video. This is so interesting!

i'll do as soon i get the touchstone kit and have some spare time to do this (hopefully on sunday...)

what happens when you place an induction charging compatible device on an induction cooking range? Will it charge the battery, or will it overload the circuitry and destroy the phone\battery?

I wonder what happens when you plug in the phone with usb while it's inductively charging.

I would think they would work together or one would be disabled by the other. Don't think they would allow both if it could cause damage.

(VIDEO) Review of the wireless charging Touchstone Back cover mod from Ebay

Here is my review video! I am a huge fan of the palm touchstone wireless charging mod and this is the best way to get it...
http://youtu.be/NGvyWBOQy0U

Nice, couple questions.
Do you use a case? I have an Otterbox Commuter and was wondering if that is thin enough to still register.
Also, will that back cover work on the Energizer Qi charging system?
Sent from my SPH-L710 using xda app-developers app

Thanks for the video!, few questions tho:
Does it work with a case (I imagine this will be a popular question)
Is the quality of the back cover noticeable different to the stock back cover? Or is it a completely stock totally 100% the same back cover with the wireless charging mod?
And what charging pad do you recommend?

Unfortunately I do not use cases as I just use a clear shield so I have no idea if it works with otterbox or any case.
This mod will not work with any pad. It will only work with the Palm Touchstone. I dont recco any pad as I only recco the touchstone. I like having one in my car, at the office and one on the nightstand.

Can you try just putting something a few mm's thick between the phone and the charge pad and seeing if it still charges?

i got this mod with a 3mm thin case from ebay. they work perfectly.
Sent from my GT-I9300 using xda app-developers app

It works with a few mm but not sure how that affects charging. Please dont just take my word for it. Dont want you spending 30 on a back cover you cant use. But if it doesnt work i will buy it from ypu for a major discount. Lol

I dont believe qi is the way to go. The new nexus has wireless charging like the touchstone. I wonder if its compatible?

probably not. afaik, each of these wireless charging is proprietary and most probably incompatible with each other. The touchstone will only work with touchstone products (atleast from what I understand, it's different frequencies and also component parts differences)

You are probably right but i hope you are wrong... either way i am so surprised more phones dont charge like this.

Frequencies have anything to do with it. I'm pretty sure inductive charging uses magnetic fields to charge your device hence the giant coil in the phone cover. BUT, each base is most likely specific to it's counter part coil as different size coils will charge at different rates from the magenet in the base vs the amount of voltage and amps they put through the magnet. So it would make sense if a say Powermat didn't work with a Touchstone coil.
On the other hand, the touchstone uses a standard phone charger so it has a maximum of 5V at 1amp. I do not know what power source the Duracell Powermat uses (looked a little but didn't search long) so if it were to use a higher voltage at the same amps or higher amps at the same voltage then it may charger your phone faster.
NOTE: It should also be noted that if you use a different charging source with the touchstone base you could end up generating a different level of voltage and in turn damage your phone. It's not recommended to do this. The downfall (that I have found) with the touchstone setup is that it WILL charge through thin TPU cases and my Rock Quicksand case BUT the magnet is not strong enough to hold the phone in place. Since the touchstone is angled and not flat the phone starts to slide down and charging stops.

You can always switch out the magnets so your phone sits better on the touchstone. Its easy to change and it can make a nice diference.

Just ordered one. Touchstone rules.

@setzer715
that's an interesting read. thanks for clarifying the differences. I skimmed on articles about different wireless charging tech and remembered a few mentions of frequencies.
If only there is a standard that can adapt or provide compatibility with other methods... but that would probably drive up costs and probably extend r&d time.

I've had wireless charging since August . . .
Have one in my car and one next to my bed. The phone locks to the wireless dock with magnets which keep it in place and at an incline rather than flat. It's nice. Cost me ~ $25 for all of it.
Oh...and mine doesn't require an ugly case like the Duracell or some sort of special back cover. Phone looks like any other S3.

Ok. I'll try compiling something later tonight. It is basically based off of the Palm Pre charging that everyone on the I9300 forums has gone over except I change the magnets so it's secure and also shave the back cover so that it doesn't bulge.

This might sound stupid but whats the point to spend 100$ on a wireless charger ? Does it really bother you that much to have a cord laying around ? I find it not very conveniant at bed time... /unless its because you need some juice and there is no power source close to you i understand

One advantage is that the micro USB connectors are a weak point in the design of most cell phones. They often break or wear out. Given the extra contacts in ours, I like the idea of avoiding the wear and tear.
But it looks like this one doesn't follow the Qi standard which our phones support with the replacement back which was promoted so I'll pass.

Sent from my SGH-T999 using xda premium

If you look at duracell's page closer, 99.99 is for a S3 "kit" , which :
Includes:
(1) Powermat® for 2 Devices
(1) Wireless Case for Samsung Galaxy S III
(1) Power On The Go
(1) Universal Power Supply (100-240VAC)
(1) Owners Manual
You can also buy the case, powermat or portable battery seperately. The bulky wireless case is 34.99 , the 2 device powermat is 49.99 and power on the go is 49.99.
I'd prefer changing only the backplate instead of having a case around it, but I guess that if you only change the backplate and put a cover on top of it, it could very likely interfere with the wireless charging being to far from the charging mat.
Samsung's own wireless recharger should be available soon somewhere, and supposedly has coils 40 percent thinner than other charger out there, keeping the backplate as thin as possible. Although, I expect the price will be high. I am pretty fed up with all the asian designed cheap accessories ordered over the net for a fraction of the price.. so I wouldn't mind spending on something that i would use as often as a charger.
99.99$ could of been a deal, if the case wasn't so damn huge.

If they would have made a blue or black version I would buy this. Can't see putting a white case on my blue phone.. ugh

Still have to provide power to the wireless charger. Fail.
I'll keep it simple (and stylish looking... man that thing is an eyesore) and plug a cord in

I don't consider it wireless charging if we have to have a gigantic bulky ugly case to do so.

Here's a link to give you a better idea of a DIY wireless charger.

My solution
I guess }{Alienz}{ isn't going to reply. I'll tell you what I did for my wireless charging needs.
I purchased the Palm Touchstone wireless dock from Amazon for about $8 and a new SIII back cover, with a touchstone compatible module to charge the battery, from e-bay for $29 (the scumbag I bought my case from is now selling them for $99) Put that cover on my phone and it looks and works like normal (including NFC), but I can now charge the phone by just putting in on the Touchstone.
Works for me and $35 is hell of a lot better than $80-$100

That's real nice and really simple to implement unlike the hacks I've seen from a few month ago. But the hacks are cheaper, lol. It may even work with the flygrip I have attached to the back of my phone. It's just at 5mm.

What's the output on these chargers? I am considering one for my N7 for a car install since otg+charging seems to be a ways off. I like the idea of the magnets which would make installation into a dashboard cubby in a Mazda 6 a piece of cake, just as long a it can provide sufficient amps to charge while the screen is on. Any feedback on this function would be appreciated!

The magnets are pretty strong on the N5, but not on the N7. I have doubts about it being able to work in a moving car. I've noticed it has to lay against the charger perfectly flat (full contact) or it won't charge. If you're going to try for a car install, then you may have better luck with a carriage and a third party Qi charger.
So far the only impressive thing (besides the charging speed) is the micro-suction pad it uses on the bottom. That sucker grips!

The dashboard in my Speed6 has a cubby/glovebox where the SatNav would be as an added option. It's a perfect place for tablet integration and I've seen others succeed. Securing the N7 should be pretty easy and I think with a piece of plexiglass/hobby board for the wireless charger to stick to it could be a very convienent addition particularly with keeping the N7 portable as opposed to plugging in the charger everytime I plan on using the tablet especially if I want to use an OTG cable with a thumb drive/microSD.

It's worth a shot. The N7's size makes it awkward to balance (IMO) since the charger itself is small.

Sweet spot.
Has anyone found the sweet spot to get N7 (2013) to charge on the Google wireless charger yet?

are the magnets in the charger enough to hold the nexus 7 in place? or is it easily knocked off?

Without a case the magnets may be strong enough to hold it in place. I've found mine is very fussy about the charger it is paired with. The supplied charger works fine but a few others I have tried refuse to work with it.

Just got this wireless charger....it works well without a case, but doesn't work with my DeviceWear case. Disappointing, but I guess not surprising.

I find when using this charger I lay it down and slide it around until the magnets feel the strongest, almost like it locks in.. Works every time.

That method works well without a case fitted, unfortunately with a case fitted the magnets are too weak to lock on in the sweet spot.

I have the official google wireless charger and have no problems finding the sweet spot anymore! When I first got it I had issues but now that I'm more accustomed to it its pretty easy! I just set the exact center of the tablet on the charger and if I miss by an inch or so the magnets drag it into the correct position! Quite nice indeed! I don't use a case though so I'm sure that's a decent factor if you use one. It chargers quite fast as well!
