What i steh port behind the battery cover?

As the title states, what on earth is it for? Some are saying its for the car kit, some say it's a charging port and I think we're all lost. Sorry I can't get a picture because the HD2 IS my camera! Anyone care to shed some light on this matter? I'm looking into a diy wireless charging solution and if these 3 pins are battery connectors, then I can use this port on the back.
Cheers!

It's for use with in car hands free and GPS. You take the back cover off and just click the phone in and hey presto, it's all snug and secure.

Any possibility of charging through this port? A few pin out diagrams would be useful but maybe I'm just pushing it now. haha

most definitely there must be... since it does charge with the car kit it seems.
You should be ok by checking with a digital tester the voltage output from those metal contacts

Good idea. I'll give that a shot now. If all goes as planned, great! But next, to work out how to jam an inductive coil behind the cover!

You'll be lucky! I think, think, you can get some whereby you need to remove the battery and the cradle fits in it's place. I would Google it, but I am hungover and feeling lazy.

Hmmm. Can't seem to find my multi meter. Anyone able to test if any of these connections have something to do with the battery terminals? At least until I can get my hands on a multi meter.

Galaxy Note Inductive Charging Mod

I modified my Galaxy Note to use inductive charging via a palm touchstone / patch.
Just a quick note. Not a whole lot to contribute here, because I largely followed the examples of the Qian Qi. That guy is awesome.
I don't think I voided a warranty, either. Only minimal teardown required (black plastic back, then the speaker section). Never came across a sticker I had to remove....
Useful links:

Notes:
- Buy a good soldering iron. Weller WESD51, set to 610 deg F, with 1/32" long conical tip, with lots of flux and lots of flux remover are the only reason I could do this. I can't stress enough the value of having good temperature control, knowledge of temperature, and so forth. I stumbled around with an "ordinary" soldering iron for a long time, and in hindsite, I can't believe I did so.
- Do not choke on the price. I already had a lot of soldering gear, and I bought $220 more. Spend the money. It's worth it.
- Watch the curious inventor youtube videos on soldering. This guy. Watch everything, several times. http://store.curiousinventor.com/
- You want 30 gauge wire. It's the only thing that just barely can be crammed in. I used the "Kynar" coated type. Buy at least 2 colors.
- as you look at the phone disassembled, with speaker on the bottom left, the +5 pin on the micro usb (MHL) port is the leftmost. I attached a wire to that, and a ground wire to the housing where the port was soldered.
- routed the wires under the speaker, then back, then into a VERY slight indentation into the battery compartment. used a blue "safe open" tool to help shape the wire / crimp ends. Once in the battery compartment, you're golden. Attach the inductive charging coil to the back of the samsung plastic back, add solder to the pads, and attach the wires.
- Attached is a picture with roughly how I routed wires. Red is +5V, Blue is ground. Be sure and double check if my recollection is right where the indentation is into the battery compartment. (that part is by memory).
- dont leave too much slack. it's really hard to get the samsung black pastic panel back on. Mine very slightly bulges.
- be careful where you put the charging sticky patch, because this phone is a little bit bigger than a palm pre. You have to consider if the phone can sit on the charger and "lock in" with the magnets. If you place it too high, it actually can't (in portrait)!
- Qian Qi had a really interesting point: most articles about how Li-ion batteries behave are wrong, and fully discharging the battery drastically reduces the number of cycles you have. So this is actually a very useful mod--whenever you don't use the phone, toss it on the charger.

Thanks for summing it up! Was actually thinking of doing this mod myself. Question: do you have a protective case on your Note? If so - what kind and how badly does it affect the magnetic properties?

No case. Especially because the note is so big, I think it would be unmanageable.
I took the samsung thin plastic back, and placed the Palm PRE (with charging coil still attached) on top of it, on the touchstone -- to figure out proper placement & mark with a pencil. I noticed a buzzing sound, coming from (I think) the induction coil on the palm pre back itself. I suspect if you use a case, this wont work well.
Also, the size/weight/placement of the galaxy note are such that the magnets are just barely strong enough to hold it. One time my phone was near, but off, the charger. I'm not sure if vibration from the phone did that, or my kids
In summary, I'm not sure how well it would work with a case. You might be able to research this on the net; among the 15 or 20 people that have bought a Pre, you might be able to find some info about the effect of a case on inductive charging.

tight squeeze?
im wanting to try this mod i have my touchstone on the way not thank you amazon but it seems like to me that the pad from the pre wouldnt fit under the cover of our phablet =/ could you post pics of the finished product and i think this is the only instance that i have seen someone attempt this with the note and i want to try it i love my note but would love it even more with inductive charging.

I am not the original author but I performed a different Touchstone mod and posted pics here:

Thank you!!!
Thank you so much for your post I have my materials on the way but I hadn't seen a detailed guide for the note other than this one and was worried I would have to solder directly to the usb pins which looked scary lol I did have two questions though would your mod work the same way for the at&t note? Specifically the points where you soldered to the phone and can wireless charging be performed through a case?

Hey, OP here. You may want to hold off just a bit. Mine is exhibiting some issues now. As in, it says "charging" but it doesn't do so wirelessly. The phone will stay "charging" but the battery % never goes up. (It was slow before, but would charge fully over a night).
Charging via USB still works.
It may be something simple; I'm not sure. But I need to crack it open and take a peek, and I haven't had time to do that yet because my phone is functional at the moment.
If nothing has conspicuously changed, there may be something about the design that isn't sustainable. Or maybe my solder joint halfway broke, or one of the wires got smashed enough so that it's partially broken...
I'll write back with my findings. Bug me if I don't

Thanks for the notice I was about to pull the trigger lol tbh I probably shouldn't attempt this I've never done a mod like this before and I'm not exactly a surgeon with a soldering iron lolvthatvbeing being said I'm going to attempt this on an old evo 4g I have before I do surgery on my baby lol plus I'm already familiar with the guts of an evo from screen repairs ill report back with my results

No prob I just wanted to see if i could do it and if I can do it with little soldering experience I'm sure most could do it I haven't done this mod to my galaxy note though as there is way less room in its a far more complicated mod than the evo because you have to make room for wires in a device samsung made as thin as possible and the way you have to route the wires I feel like the solder joints would just break

For those who want to try this out but still have warrantee just buy a backcover, a micro usb plug and assemble it according to the directions here.If you need the note just take out the usb plug and the back cover and you're good to go.... Or leave it there.....
For those who don't know what pins to use on the usb plug:
Pin: 1 is 5V+ (red)
Pin: 5 is GND (black)
Works like a charm.......

I was not a big stylus user; I can't stand the input lag. I didn't notice a difference, but I always considered the input speed unacceptable. Not sure why there would be any difference, anyway.
My big problem that I've never taken the time to address is that after some time, it's as though I can't pull enough current through the wires to charge. One day I need to crack this open & figure out why.

Galaxy s4 wireless charging?

So I just bought this wireless charging dock last night: http://pages.ebay.com/link/?nav=item.view&id=400461623073
And thought that this is all I would need in order to charge my battery. However, Now I'm worried I will need a battery door. Does anyone know git certain whether or not I will need a different battery door to use wireless charging (currently using the one that came out of the box) if so, where would I be able to find one at? Thanks in advance!

Don't need to get a new battery door. That new Samsung door will actually be larger than the current one. Some/many cases won't fit.

I pre-ordered the one for the S4, after it was written up on Engadget. It hasn't been released yet, apparently, so I'm still waiting.
Here's the Engadget article. Some good things said about it in the comments:
http://www.engadget.com/2013/04/10/monster-watts-wiqiqi-slips-wireless-charging-into-samsung-galaxy/
The order site says that it will ship by May 31:

Well, I just bought it. Will review it when I receive it on the 31st.

Samsung is terrible with the S4 accessories.. they release a new battery cover just to enable wireless charging.. ok fine.. but they release a stupid 70bux transparent flip cover that doesn't support wireless charging.. so basically i can never get wireless charging if i ever want to use their oem products or i need a special case if i want to use their oem wireless charging cover and fit?? real smart thinking.. guess i'll give this kit a try too

I thought it was the battery it self that has a coil in it for the NFC and that was for charging?
if not I have my palm pre still that has that wireless charging - could I take that battery cover apart and take that coil out and just attach it to the inside of the phone
I dont see anywhere where a battery cover with this built in will connect inside like it does on the palm pre, there arent any contacts that I can see that will go to the battery charting how would this work

Are you sure you are looking at a GS4?
There are 4 contacts. 2 to the left and 2 to the right of the flash. I think the left ones are for charging. I am basically ready to do what you said but need to figure out the polarity of these contacts.
There are other related threads but no responses yet...

To the guy worrying about the flip cover - there are tons of wireless charging inserts on eBay. You don't need the Samsung back, just get one of those things and stick it under the cover.

I'm hoping yours worked. I've had a qi receiver in my S3 for about 6 months now. I pulled it out to see if it would work in my S4 and it doesn't quite fit. The pad would fit, but it lays over the sim card and mSdcard, which probably wouldn't be a big deal, but the problem is the two small brass contacts don't quite fit in the square charging holes on the s4, they're probably 0.25mm too large and slightly to far apart for the S4.
My S3 pad is about 6 months old though, so hopefully the newer s3 pads have been modified to work with both phones.
I love wireless charging though and just went ahead and ordered a qi pad for my s4 from the fastech link earlier in this thread.

Does the Note4 support wireless charging?

I haven't seen this covered and if it has been, I'd appreciate anyone posting a link to the article. Does the Note4 support wireless charging or will we have to get one of those stickers as we have to do for the Note 3?
Thanks in advance
nevermind, answered my own question, same crap. How come they can include wireless charging in the S5 but not in the Note4? Seems like they did some great stuff that seemed very basic and rushed the Note4 out without the same tech such as dust and waterproof. I don't get it.

I have been wondering the same thing. I certainly won't get one unless it has Qi charging. I am assuming they will release a wireless back cover again.

I don't want to buy another back or another "sticker". How is it other models have it built in and this, their "latest" version doesn't? This is truly a step backward in the Note series. Huawei's devices are looking very nice right now.

I wonder if the quick charging will work with wireless charging?

No. They are two separate things... a given Qi charger only puts out a limited amount of power.

Do the Huawei phones have wireless charging? After you mentioned Huawei I checked out some of their best devices but couldn't see any wireless charging options.

If it is wireless charging, does it mean it will have a magnetic back? I need that so I can stick it to my car CD slot caddy.

^^What he said^^ and theres no way any wireless charger can do that, also given my experience with the LG G3 I am not ruling out damage to the battery or device due to overheating whilst wireless charging, my battery life on G3 perished after such time as I started using wireless charger.
I may be wrong, however, its fairly coincidental.
On a related note the pins are definitely there for wireless charging but no coil as far as I can tell.

Note 4 DOES support wireless charging with the correct door and or cheap coil which im sure will be available soon.

Glad to hear that it supports Qi charging (with add on). Since going wireless on my Note 3 I'll never plug my phone in again.

I'm pretty sure the reason the Note wasn't certified dust and water-resistant is the large long opening in it to accommodate the S-Pen.

I don't see why Samsung or any smartphone company hasn't started using the vapor/nano-coat waterproofing. It wouldn't matter how big any hole is. See HzO, P2i and others.
The day I get my Note 4 I'm sending it in to get 'vaporized'. Only ~50 bucks, totally worth it for a $1000 device that fits in your pocket.

Idk why Samsung doesn't include the wireless charging back to begin with. That way all the cases would still fit it. It's irritating to say the least.

Same here. I use the stock samsung wireless cover I think I got for 20 bucks for my note 3. It works great with the TYLT and I don't use usb anymore. Even when traveling I have a portable battery "ravpower" with QI built in and it works great.

Because then they couldnt charge you the $40 for a new back.

very interesting... Still really risky, you will have to void the warranty to do this and if you don't shield the heat or if the wire touches something wrong it could brick. Just be careful guys. Zsnaps is a safer alternative that makes charging simple. Wish they would ship already

Why can't someone make a bumper case for the 5X that incorporates a Qi charging coil and plugs into the USB socket? I think there are auxiliary batteries for some phones like that. That would work for me.

Agreed. And (surprising to me) not everyone likes wireless charging. I hope the intersection of the two (and the 5x community) is big enough to warrant market attention.

I asked the poster ,xCubicle....
What's the large light grey patch on the inside of the back cover?
It can be seen in the ifixit teardown images at step 4.
Got the response...
"useless sticker. peeled it off."
I couldn't help but think back to the AMA
specifically the part "...Meanwhile, wireless charging adds z (thickness)..."
So what's the deal here with the blatant capability of qi wireless being designed into the rear case but the spec being deleted...?

It's because they did not want to give qi to the 5x and leave it out of the 6p because it has an aluminum body.

I'm pretty sure you hit the nail on the head here.

It wouldn't have been as bad if they'd just said that, but the bull****ting about thickness as an excuse is not cool.

after further testing with the mod. i am indeed able to charge wirelessly up to 100% from 0%. i measured the wireless charging current and it seems to range from 100-500ma charge rate. a typical charger ranges from 1000-2500ma charge rate.
regardless, its a working mod so far.
i need to refine the wiring to layout to make it a bit more appealing before i offer it as a modding service.

Awesome news. Looking forward to potentially doing this mod myself!

I bought this for my Nexus 7. Yep it is the largest one, you can even buy it from a Verizon store.

Charging time
Can anyone comment on the wireless charging time with the mod compared to the wireless charging time on the older Nexus 5 which had it built in?
In the same boat as many, where the lack of Qi has prevented me from upgrading

What will happen if wireless charging and USB Charging together?

Not even sure what happens now
To answer my own question form my last post. "Even the more expensive Qi modules appear to charge slower than the factory built in modules". Not sure what the reason for would be? Or people do not realize they are buying lower powered (yet more expensive) modules. Most posts I have seen refer to 500mAh modules
