Any way to enable wireless charging? Possibly removing the back and with a touchstone similar to what's possible with the s3?

Most places are declining to make this

We need moto to make these kinda features stock

The problem is the phone is not designed to be opened or the battery removed.. hence voiding warranty if u do so

That's why we prob won't see this for the RAZR HD and HD maxx


With the s3 u can just pop the back door off...this phone I have yet to see a breakdown... I really doubt the aftermarket companies that make those kinda product will want to invest in making a product that voids ur warranty just to install it

This is xda surely warranties aren't a concern? If i saw a tear down it wouldn't be hard to set it up with a touch stone like the s3 i would think?

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.
