Here ya go! Keep in mind that this is my wireless volt mod (as in, the way I did it) and as such, any improvements are welcome! I'm very happy with the mod so far. The phone did a full charge over night with no problems. It was very nice just to pick it up off the touchstone this morning! But as usual do this at your own risk! The person doing the mod should be reasonably proficient at soldering small joints. Just be careful and this will work for you. Instructions are on the JPG! Any questions please ask! Verified working on the stock kernel and stock charger.

Vinas, do you use battery monitor pro or have other software to tell you charging current? Also are you using Perseus's kernel? Should up charging rate from about 350-500 ma to 900 ma.

Great point, yes I'm using Perseus's kernel with this. I was at about 40% last night and woke up this morning with 100%. I'll check out the charging current - I have a full charge now so give me like 14 hours (ha ha)! One interesting thing to note (no pun intended) is that I was having a problem with non-oem chargers. It seems like the charger needs at least 750 milliamps of output to work - the OEM charger has 2 amps. The OEM part number is ETA-U90JWE. I have some crappy blackberry chargers that are hit or miss - my samsung 750milliamp works and so does the OEM like I stated before.

Does it start indicating charging immediately or does it take 5-10 seconds to register like my Galaxy Nexus did?

It starts immediately within about 1 maybe 2 seconds at the most.

I used the smallest wire I had which was about 26 Guage. I salvaged the wire from a micro usb cable that I was using to test this mod. Afterwards I realized I could have used copper conductive tape. If I were to redo the mod i'd probably use the copper tape instead.
At the time I was worried about shorting other components, so I opted for super thin insulated wire.

If I get a minute to tear down my phone again I will. It's been sitting apart more than together during the last day... The parts I used were salvaged from a micro usb cable for the wire, and I used a thin piece of plastic to wedge the usb compartment down. The plastic bit I used was rectangular and about as thick as a credit card.

Edit: Pics attached of the wire and plastic piece I used.

I'm assuming you used some N52 magnets perhaps, maybe 8 of them? Glad to hear you used 26 ga cause I got copper tape and 30 ga wire ready to go. I think I'll use the wire to avoid shorting as well.

I just tested the stock kernel again and can confirm that the disconnect problem with weaker chargers is not present. It seems that the higher charge rate in the Perseus kernel causes the weaker micro USB chargers to disconnect. The OEM charger works just fine, but due to the higher charge rate and the palm touchstone, it seems that the lesser amperage chargers can't keep up. The symptom when this happens is: set phone on palm touchstone, USB connects and disconnects over and over again. Again, not a problem on the stock kernel.
