i9000 induction charging mod

Ok, This seems like such a obvious thing to do that there must be a reason it hasn't been done yet.
The idea, the galaxy s i9000 has a thin plastic back cover, which wouldn't interfere with an induction charging mod. So why hasn't one been done yet?
secondary question:
via induction charging; Is it possible to charge directly to the battery connectors? or does the charge need to go through the USB port to work? I think it's a bit ugly having wires protruding out that then need to connect to a usb head and then plug into the phone... I imagine that the battery may still charge with a direct charge to the battery, but the software may not control it. (i.e. no awareness that the phone is on charge)
What do you guys think?
Cheers,
Evan

Possible? Yes. Safe? No.

Direct connection to the battery will probably overcharge the battery.

Palm Pre has it, and there was a mod for an Evo 4G using the Palm Pre coil; so a mod is perhaps technically possible. But I wouldn’t mess around with it. Inductive charging is inefficient add produces more heat compared to normal charging. Galaxy S heats up while charging even the normal way, I don’t want to make it worse.
As for charging methods, generally speaking, I much prefer open charging contacts with a desktop cradle like design (like used in home cordless phones) over inductive charging.

wouldn't necessarily overcharge if a charge controller was in place. (direct connection to battery)

Still here , and Phone including the mod are still working.
I'm quite satisfied with the mod, the only real flaw is that the compass is practically unuseable (but I never really used the compass, so i don't care)
And I does charge a little slower , the back (were the coil is sitting) gets warm after sometime , but nothing to worry about (maybe 38°C).
I would not recommend to charge the battery directly the 5V that the coil "produces" may not only overcharge the battery but may also destroy parts of the phone.
I connected the wires to the usb-port (Internally), so its like you are charging over the usb port, so there's no risk of overcharging.

Any details on how you did that? from the other thread it looks like you have one wire running off to a screw (ground point?) and another directly to the battery.

take a look at this:

well thats awsome although im a bit worried about messing with my phone

He's already ordered parts for making a fully invisible inductive charging mod (with the MicroUSB slot being completely free) so check the website in about a week or two.

can't get hold of a palm pre back... so need to make our own coil. But what length does the coil need to be?

This is all very impressive. But induction charging seems pretty useless since you can't really use the phone while charging.

Touchscreen issues when charging

Anyone having issues with your touch screen when you are using it while it's chArging? Just wondering if i have a faulty device or are there others with the same problem
Sent from my HTC One X using xda premium

No my device does not have this issue when charging. I think this issue has something to do with the charger.

That's a grounding problem, had it with my SGSII try a different cable.

The sensation had an issue of touchscreen problems while charging. i went through 3 phones. The cause is the same cause as the wifi errors that people are having with the HOX. Bad connection from unibody(sensation) to board.. If we added aluminum foil or solder (just like the HOX wifi issue) it would fix the problem. On the sensation the problem got really bad to where you couldnt unlock the phone with the lockring. grounding issue. I hope the HOX isnt having that same issue and you just have a bum phone or better yet a bum cord or charger. let us know if its either

yeah happened alot on my s2, was due to usb cable or something
but works fine when im charging

It was the grounding issue, does this damage the phone? I have a wall outlet with USB ports so it might emit too much power

Every time this has happened it has been because of what the USB cable was plugged in to and not the cable itself. Try the charger it came with in a regular plug. If it doesn't work better then it is a phone problem.

This happens to me too. Charging from the laptop with an eBay (chinese) cable causes the touchscreen to be unresponsive.
Here's how to test: Open the Notes and draw a few lines very fast.

Here is a video of it happening to me on my skyrocket. It was because of the charger. Try a different cable, then a different wall adapter.

It is because of the charger...it's always recommended to use the charger that came with the phone eventhough they give us a tiny a$$ USB cable.

Yes, I have an issue - when the phone gets to 90%+ while charging, the screen becomes very unresponsive. The drags don't drag - instead the touches are registered as taps.
You can get an app like MultiTouch Test - and you will see, it's very clear to see when this happens.
My first One X device did not have this issue, so it's something specific to my current unit. Doesn't bother me much, since it only happens at 90%+ charge, while plugged in...

To me it doesn't happen all the time, sometimes it happens, sometimes it doesn't. Unplugging the cable and plugging it back in seems to temporarily fix the problem, if I leave it charging for a couple more minutes, I think the problem will come back, but again, unplugging/plugging it back, solves it temporarily. It's weird...
Oh, and all this to say that I observed this behavior while charging around 65%, not 90%. And I've only observed this while charging with AC power with the original cable and charger. The problem did not present itself (yet) while charging through USB.

I just had this happen with the stock charger from my old HTC One using it on my HTC One X. Along with touchscreen problems it got VERY hot located as you are looking at the camera side it got hot on the top right side near the camera. Dunno what that could be. Both chargers are rated at the same voltage and amperage, I dont get it

It's caused by electrical noise. The voltage supplied from your mains outlet is alternating current (typically 50/60hz in frequency). a usb charger has to do two things; firstly step down the voltage (110v/230v/240v down to 5v) and secondly rectify the alternating current into direct current (positive and negative). how it does this is by using a transformer which employs an iron core surrounded by copper windings, this generates a lot of rf (radio) which travels down the cables to the device as well as broadcasting a short distance through the air, a decent charger will use shielding as well as a few other pieces of circuitry which will neutralize the rf given off. In order to rectify the voltage the charger will use a variety of diodes and capitors, in a cheap Chinese charger they will typically use as little as 2 and possibly a generic chemical capacitor (similar to a small battery) these degrade over time and can get quite hot, fat and eventually burst - when you hear about chargers exploding or setting on fire it's usually because the capitors aren't up to the job. a Chinese charger may have all the quality control and certification stamps but most of them are forged, if you buy a charger for less than $10 this is what your likely to end up with. the outputted voltage may appear 5v on a multimeter but they are a very dirty output and can spike from 3v to 7v or even more the load on the charger increases. The dirty output interferes with the mechanism used on touch screen devices which also employ a type of capacitance to register where you are pressing on the screen. A decent charger will use solid state capitors and which should last a lifetime.
if the smartphone miss behaves whilst charging 90% of the time it's because of a faulty charging device (or one employing poor components). a decent charger may cost more $20 but they are significantly safer for both you and the device.
The problem with mains sockets with built in usb usually comes down to shielding, they will either have none or be earthed (which might sound like a good idea but in practise a lot of domestic devices will create leakage to earth causing more noise - alot of studio equipment will have a separate earth). These may not be as dangerous as cheap Chinese chargers but still undesirable.
If a original or good quality charger isn't available one of the best sources for charging a phone will actually be a desktop pc with a usb3 port. The whole pc is insulated in a nice metal case and there are a plefora of high quality components to create a stable clean power supply (a cpu voltage tolerance is usually measured to 2 decimal places of a volt which is pretty good).
Ditch the rubbish cheap chargers, you honestly get what you pay for and they aren't good for the long term health of the phone. If it hums or makes a high pitch noise whilst plugged in your playing with fire - literally. they aren't bothered if your phone dies in 6 months or bursts into flames so long as they get the $5 x 100,000 people who buy them (these things literally cost pennies for them to put together, even though the case might look the business inside they are nasty and as cheap as)

Very insightful. The worst part is that I have two original HTC chargers and they both emit the high pitched noise.

Some of the very small chargers might whistle a little, its called coil noise and isn't as bad as capacitors about to pop. The iron core hasn't been sufficiently dampened or glued into the case so it resonates when the ac passes through it, the pitch may change depending on the voltage (whether its a 230v or 110v power supply). It isn't unsafe but HTC should be doing a better job at checking the new chargers, over time most chargers will develop coil noise as glue tends to melt or degrade.
Very insightful video, you'll never buy a cheap charger again
https://www.youtube.com/watch?v=wi-b9k-0KfE&feature=youtube_gdata_player
The gist being the cheap chargers could very well set on fire and the USB could go live at mains voltage with no circuit protection, death traps spring to mind. Be careful what you buy.

[Q] Charging problem

a few days back my phone started to charge slower and gradually it stopped charging at times. It only charged if i moved/bent it or keep it supported on some object.
It worked fine with Nokia Lumia800 cable so i bought a new cable today but have the same problems.What can be the problem here ?

Try sharpening a toothpick so it will fit in your phone's usb slot, then gently move it around in there and scrape out anything that could be in there. Over time dust and lint will accumulate in there which could cause a poor connection, which could in turn cause charging problems. Just be very careful so that you don't break anything. The nokia cable might be slightly different and that's why it would work and the other's wouldn't.

If you have an air compressor I would use that or some type of high out put air and blow inside the input for the charger
Sent from my Nexus 7 using Tapatalk 2

It's also possible that something has cracked. In that case, from now on be very careful when inserting/removing the cable. You may need to apply gentle pressure on the cabke in 1 direction during charging.

Not even worth trying, I attempted this mod on the Atrix HD which is done by connecting the positive terminal on the palm pixi to the +5v part on phone and it eventually worked but a usb had to be plugged into phone the usb wasnt plugged into anything but the phone wouldnt charge unless it actually detected a usb plugged in.

Unfortunately, I don't think it will happen. It is true that XDA doesn't care too much about warranties, but there is a big difference between hardware and software warranties. Accessory manufacturers aren't going to make something that you have to hack apart your phone for. What is worth more to you, a 30 dollar wireless charging accessory that you have to jimmy rig, or the warranty that protects your $650 investment? You can unroot easy enough to return to VZW but try explaning the wireless charging mod that's on there now.

I've been interested in getting a wireless charging solution for my phone, and while I have to look into it a bit more to figure out specifics for certain things, I think it may be possible to create a case that plugs into the USB port so we wouldn't void our warranties.
Designing the case wont bee too much hassle, a micrometer and some 3D modeling software. However we need to find a way to get a micro usb connector that has a 90 degree bend in it to go into the port without causing any sort of scraping. Possibly have the right hand side of the case hinged and secured by snaps on top and bottom? or have the connector itself removable.
So materials for a test setup would require:
Touchstone components
90 degree MicroUSB male connector
Soldering gun
Custom case
I don't have the setup to do this available to me right now, however I think the biggest problem would be getting a connector small enough to keep from adding a lot of bulk to the side of the phone. Heck, with it only supplying .42 A at about 4.8 volts, it may not be inconceivable to group 2 in a case for faster charging. I haven't worked with the touchstone charger myself before, so I don't know their size.
Anyways, food for thought, and a possible personal project once I get some more important things finished up.

Hi,
Signed up just to post my results so far.
Ive gotten razr HD maxx to charge through the USB port using a touchstone pixi back cover.
It works using the touchstone charging base but the usb wall wart that came with the razr hd. The amperage coming though was not enough using a motorola dedicated usb wall charger that came with my bluetooth headphones putting out 500mA. It charges a little slower using the induction charger. I need to figure out if this will work running off my cars electrical system as that is my main motivation for getting this to work.
To get the phone to go into charging mode you have to either short out the USB data wires or connect the D+ wire to a 2v contact on the touchstone pixi circuit. Connecting the usb D+ to the 2v contact hopefully will allow me to hardwire this setup directly to the phone and leave the usb port free if, assuming I can find enough room inside for everything.
The phone is charging right now on the touchstone base, estimate 2hr to full charge from 70%
Im going to try and shove it all inside the phone tomorrow.

I dont know if I can get this to work internally now due to soldeirng limitations.
There is just enough space to slightly force the phone back together (it does bulge) but the pins for the USB port are covered and recessed under the USB housing. There is not enough clearance for me to do a clean solder onto the contacts.
I can not find another trace for the 5v or D+ pin on the circuit board.
If i could remove the outer cover maybe but for now this is going to have to be a plug into the USB port/external mod until i either grow a bigger pair and try to remove the USB port or find alternate contacts to solder the leads onto.
EDIT: I actually just went for it and ground off the corner of the USB casing. And actually soldered the wires onto the pins. However the touchstone system will not allow this to work internally. The battey when laid on the coil will interfere with the EMF and cause an unstable voltage. It goes from a low of 4.8 to 5.5 v. Maybe someone thats an RF engineer can figure something out with the reflector.
Maybe if i get more motivation later ill check out a qi standard charging setup to see if its compatible. For now im going to find an outer case and just go with the usb plug use this externally.

Try picking up some foil tape and put it between the battery and coil. You should be able to pick some up at your local hardware or hobby shop. It may need to be touching the ground to be effective though. Depending on some things over the next month I might be able to start working on my own setup.

Tried that but no go.
With the foil covering the coil, the voltage fluctuates before the battery is even placed over it. I hope you can get it working internally, ive since used an otterbox commuter case to hold it all together.

In what order are you putting the components? Phone, battery then coil. Or phone coil then battery? Basically is the coil between the hardware and battery, or is the coil between the back panel and battery.
I can see where the issues would arise if it is between the battery and hardware. Both would be giving off EM waves if the device is on. If it is between them, try moving the coil to between the back panel and the battery.
Right now I can't afford to try an internal mod where I could kill the phone if I screw up, so until a couple things settle down for me I will only be attempting an external mod that fits in a case. If I can get the design right I may be able to make it so there is still a USB port available.
*Edit*
I'm sourcing/pricing components right now and you've already given me the voltage output, but how about the current provided by the coil? What I'm planning involves building a small circuit that would short the D+ wire only when there is no USB cable connected.

Anyway we can get some pics of the project in progress?

So I don't have the components at the moment to start my project physically, however as I said I am finding the parts I'll need. Apparently its a PITA to get male micro USB connectors without bulk orders, or importing from China. I'd prefer a SMT (surface mount for circuit boards) but those appear to be next to impossible. Anyways I've been able to find pretty much everything I need and just a matter of time till they get in.
My plan is to provide a clean circuit that would use the USB port on the phone to charge using the coil, while adding a new USB port into a phone case to still allow USB data and charging. However as the coil can create fluctuations in voltage and current, I want to have a setup that allows for it to be isolated while it is plugged in through USB.
Attached is just a quick circuit diagram I made using EveryCircuit, I need to refine it still, but just an example. Heck if you have the app rebuild it and you'll be able to see what it does. Left side is USB cable input, with a switch at top to simulate plugging in and unplugging, while the right is the phone side with the power source being the coil. The light/loads are to simulate the data lines and power lines and show whether the circuit works.
When I get the parts together I'll take pics and post a tutorial. I have some 3D modeling experience so I may even be able to design a custom case to put everything into.

the coil was sandwiched between the back case of the phone and the battery. The metal in the battery is influencing the flux going through the charging coil. The base is not always on, it only turns on when the charging coil is present. If not present the base seems to send out a pulse every so often to detect the presence of the charging coil inside the phone.
The issues arise once the battery is laid across the coil, the base begins to oscillate and the voltage begins to alternate. Also the coils seem to only work within a specific frequency range, but i dont have a signal generator or oscope to confirm this.
According to the battery charging app the base is putting out ~6-700mA to the phone with an 1A charger plugged into the base.

That's my theory since the nexus 6 has wireless and they are the same chassis essentially . or it was for a fingerprint scanner they abandoned. Once we see a nexus 6 teardown we will have a better idea if we can do it.

Could have sworn I read somewhere that between they cable and a teardown of the software showing code for a fingerprint scanner, the original idea was to have the scanner. I could be wrong though.

Let's hope you're wrong then.
It would be really cool to have wireless charging, shame so few manufacturers add this.
The amount of stuff needed to make the coils on the receiving end is pretty limited, I could absolutely accept buying the transmitter separately, (like the turbo charger is now)
But I suspect the patent royalties are expensive, patents sure don't benefit users..

Looks like the nexus 6 has a different config then the moto x so as far as a plug and play solution, no. I have located 2 contact locations where we could solder in a qi coil. I'm just trying to work up the courage to try it lol

Here is a related question: without modding the phone itself on the 2013 and 2014 model I cant get one of the QI receivers to work. This is the one for sale on eBay / amazon / newegg with a micro usb end to plug into the micro usb port. It literally works with every other micro usb device i own including a Samsung bluetooth headset, several phones and some other stuff i cant think of at the moment... On the moto x 2013 and 14 I literally see no charge and see it actively loose charge over time with this device plugged in.

It may be tricky with the moto x. There are some negative and some positive reviews here for example: http://www.amazon.com/gp/aw/cr/B00MN3RR7Q/s=sd/ref=mw_dp_cr
There are also some reviews saying they needed to restart the device once while on the charger: http://www.amazon.com/gp/aw/review/B00H7FJX7M/R2YPDLOU1BD4QE/ref=mw_dp_cr?cursor=2&sort=rd
You can find more of those comments on the internet. Could you try that, and if it works clarify if you need to restart it every time you want to charge or every time you connect something else?
Here is another link for the original moto x: http://www.reddit.com/r/MotoX/comments/2gskxw/original_moto_x_wireless_charging_mod_qi/
Edit: you may need a screen lock, e.g. the pattern lock.
http://forum.xda-developers.com/showthread.php?t=2596469
An unrooted Moto G needs to be screen locked (I use the pattern lock type) or it will refuse to charge due to the missing pins. You can unlock the screen while it is charging as long as you don't lift it from the qi charger. (tested on 4.3 and 4.4.2, DE and FR firmware)

Looks like the nexus 6 has a different config then the moto x so as far as a plug and play solution, no. I have located 2 contact locations where we could solder in a qi coil. I'm just trying to work up the courage to try it lol

Go for it lol! Take some nice pics if you do. You'd be my hero.

Well chaps, bad news. I don't think this is going to be possible. I spent 6 hours today trying various solder points. Couldn't get any of them to actually charge the battery. Seems to be some sort of system configuration thats interfering with how its detecting .

Did you look at /sys/module/msm_otg/parameters/floated_charger_enable? It might not be enabled. Here's a similar thread for the Moto G:

http://forum.xda-developers.com/showthread.php?t=2601628 (thread for the app, not sure it works on X2 but you can check manually through ADB for the above /sys path).
As far as I know, wireless charging won't work without a pattern lock or having that option set. My Moto X won't be here until next week so I can't do any testing until then.

I tried pattern lock, didn't help. Wireless charging does not require a lock, my girlfriend has a droid maxx and wireless works without it.
As far as the module check, I don't have root on Verizon so I wouldn't be able to test it.

You are correct about wireless charging in general. I think the reason the pattern lock is suggested is because the wireless mod (even without internally mounting it) only provides 2 wires on the USB connector. Something about only having 2 wires, and not the data pins, is why the locking is suggested.
No worries on the module, just something I had seen while investigating. I don't know if the Maxx supported wireless charging out of the box, but it may have the flag enabled by default (that flag seems common among many Moto devices).
I'm coming from a Nexus 5 and I'll really miss wireless charging, hence my questions to you

The Maxx has it built in from moto, same internals as the moto x essentially. If we get root I could look at the module thing. I was lucky that I had access to a spare moto x main board so I didn't have to solder on mine. That won't be the case in the future.
I'm going to post all the points I tried so maybe someone can figure this out. I was able to get it to show charging but only right after reboot and it would stop once I took it off and replaced it. I have to emphasize it showed charging but never actually charged the battery, it would show charging in battery stats bit not in the status bar. I also use battery monitor widget to check the current and it never showed positive charge current. Once I was able to get it to details at as a USB charge, only happened once, still didn't charge though.
This all makes me think there is something screwy going on.

I ordered a Pure Edition (Cyber Monday deal was a great one) so if nothing else I'll have root to poke around. Pictures of where you tried would definitely be helpful. I think I saw some from you in another thread, but all in one place would make searching easier
A 5V near the USB port would be ideal because then we'd know its likely feeding into the battery or charge circuit. 5V elsewhere on the board may not be wired to the battery. Looking at the photos in that Moto G thread may give you an idea on where to poke around with a multimeter.
The charging after a reboot, and until you picked it up, sounds like maybe you did have it at one point. That whole "until you pick it up" is another thing mentioned by many in those Moto G threads.
What wireless charging receiver did you use (not your base station)? The one I ordered says "up to 1000mAh" but I had seen some at 500 or 650. A lower output rating may not be enough to charge the battery at all. One way to test this would be a very low output wall charger (one that puts out 500mAh for example) and see if the X shows charging when connected to that.
On a related note, how hard is it to disassemble the X? Some of the teardowns look like it could be a pain.

i've attache da picture of the points i used and the results are as follows.
1. shows 5v when plugged in. when wireless coil is attached to it, will power the phone up without the battery connected (doesn't boot, just shows a battery on screen)
2. pretty much exactly the same as spot 1
3. shows 5volts but doesn't power the phone
4. shows 5v but doesn't power the phone
5. you can't see it in the picture because the rubber cover for the usb port is on but there is a diode right behind the usb port. this one is the only port i was able to get it to say usb charging ONCE. other then that, acts the same as 1 and 2.
again i have to emphasize that even though they show charging initially, they never actually charge the battery.
I'm using a galaxy s3 qi insert 700ma. i think there is a mislabeling on some qi pads saying 1000ma but not considering the 30% loss in inductive charging. even ones with 1000 on them tend to charge around 650ma. some label including the loss.
As far as teardown it's not too complicated to get the back off, lots of adhesive so be careful to not bend the back cover. i have leather so that was a particular hassle as i didn't want creases in the leather. after that there are 17 screws to remove. i've included a picture of the ones you need to remove. the ones around the silver ring on the "moto" logo don't need to be removed along with the silver screw for the buttons.
after you remove the screws and disconnect the buttons and battery from the board the back battery plate comes off in one piece. one of the particularly hard parts about testing points is you can't turn the phone on because the power button is part of the battery plate. also when you put the battery plate back on and you have wires running to contact points it won't fit because there is a speaker "box" that sections off that circuitry. i combated this by using copper tape to essentially make my own tiny custom circuit pathways leading out of that box where i then could attach wires and run them up through the hole that the battery connector goes.
THIS IS NOT FOR THE FAINT OF HEART!

i'm going to write up a tear down guide for this phone. what section do you guys think i should post it in?
