don't think so. it does support "fast charging", though i do not know what voltages/standards.
thanks, i need that. too bad
NO
QI charging with aluminium body? Hääää... ???
i think this will be not possible because the metal body fully isolate any induction coil!
Keyword: "Faraday Cage"
the only way i know is this way: click combinated with a softcase!
But if you will use this, some phone can not go into deepsleep mode any longer!!!! This will drain your battery too!

Look here, Schlaumeier: Qualcomm is first to announce wireless charging for metal smartphones and more
and? do you feel better now??
anyway! QI-charging is impossible at this time and in the future!! The name of the new technology you told me is "WiPower"! It based on Near Field Magnetic Resonance! This is a absolutely different technology!

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.

Haha! big night out I see!
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.
hey guys,
So i noticed 2 extra pins under the battery cover of my GN2 today! i looks like they are for wireless charging similar to what Samsung promised for the gs3. I don't really feel like waiting for the official wireless charging kit from Samsung so I'm going to attempt to make my own wireless charging back! I've seen videos like this before so i know it can be done! i have got the old inductive charger and back from my ancient palm pre so I'm going to give it a shot! just thought id spark up a bit of conversation about the topic and maybe learn a bit from some people who may already have done something similar!
I apologize in for the terrible grammar
thanks !
Isn't that for NFC? My original note had those and they matched up with the contact points on the battery cover and its nfc chip

As you can see in his pic the Note 2 has two sets of pins... One set (the upper pins) is for the NFC that lines up with the battery cover and the other set (next to the battery) is "most likely" for wireless charging because I did my own mod for the S3 and it works perfect but until someone does it we don't know for sure??
that's NFC

The whole mod cost me $18.00 on my S3 so that's how much it costs for everything... It's real simple too! I KNEW those bottom pins were for charging but some people just kept saying both sets of pins were for NFC which would be WRONG.... :highfive: Follow this thread and you can get all the stuff on Amazon... You will probably need some of the stronger magnets though which are another $10.00 for 100 of them on Ebay...

can anyone clarify:
which pin is + and -
what is the max current (at 5 volts?)
and other than getting the correct voltage, is there anything else that a wireless charging back-plate would need to do? (I am thinking of making a simple one with a LM7805 + a diode and a coil)
I'm waiting for the official Samsung one. I hope it does 2A wireless charging ! hehe.

magnetic fields only induce current when the field changes(think transformer). It's AC not DC.

How long does it take to fully charge the phone? Because the palm's wireless charging module's output current is far lower than the samsung one as far as i knows.
It's limited in the kernel to .5A, optimally 6.2 hours.

What current? I thought current referred to electrons flowing down a wire. It is wire less.

Mate. Wiki how a transformer works. Its basically 2 coils set next to each other. The coil in the dock has current flowing through it and this creates a magnetic field. This local magnetic field pushes the electrons around in the coil we have put in the back of our phones and tadaaa! Current. Electrmagnetism into Electromagnetic induction. So we dont want more than 0.5A in the case coil.
By the way see http://forum.xda-developers.com/showthread.php?t=1951493 for 2 common solutions to the mod (soldered and non-soldered) my non-soldered solution works a treat.

Dude, I am an electrical engineer. It's more complicated than that. Only changing magnetic fields generate electric fields that induce current in a wire. The current is AC. 0.5A makes no sense, to me.

USB Type-C's connector is designed for many many cycles of use. It's supposed much more durable than Micro-USB, so it should be fine.

Probably because you don't try jamming it in backwards half the time.

I'm not personally too concerned about my port, but as a repair tech, these will be a ***** and a half to replace.

I doubt LG bothers with that. They just chuck the broken unit in the trash and send a new one. If you mean some mall kiosk/street vendor/fly by night internet operation, then yes, that sucks for them.
Looks easy to repair reminds me of my iPhone 3gs. It was 24k jailbroke for life I replaced the battery and speaker in it
Hi
Interesting it has 3 microphones, there is one top and bottom (externally visible by the small holes top and bottom) plus one on the earpiece.

I have to believe it is something like the Tylt Vu. It has three coils and is quite tall.
This mod makes me happy as I wait for my N5X to be delivered but that theme just brings back a memory from the only time I've shedded a tear in a video game.
Sent from my SM-G920F
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

not charger. but a receiver pad.
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
hi
i got a phone that doesnt charge and barely turn on, i think its the battery connector that is defected on the phone. The pins doesnt looks good. Im wondering if its hard to replace the battery connector myself ? or is there a way to recable a way to pass the battery connectors pins ?

Well yes, that's a workaround. You can still buy a Qi-enabled back door or just buy the paper that goes conected to the pins and place it between the battery and the back cover itself (I don't remember the name, but there are a lot in Amazon or Aliexpress).
By the way if you want this phone to be your daily driver, I suggest you to get it fixed. Wireless charging is painfully slow, phone cases doesn't fit with aftermarket Qi enablers or even the genuine back door and they probably don't work with the charging base either. Also with WiFi you wouldn't be able to transfer files or even flash roms between your phone and your pc as fast as with an USB cable. Now if it will be your secondary phone then sure, grab a Qi cover or get an external battery charger and problem solved. Good luck!
