I have done a "Touchstone" mod to my phone, And found something interestiing.
When i did the mod, I also installed an led in the receiving end of the touchstone inductance charger to checkup on its status. See pics here:
hehe, did my NDSi too :P
Anywho... I found something interesting..
Now i know our chipsets dont support USB Host mode..
But, For some reason, The usb port on the phone Will
output 5v during bootup for a second or two.
Being that my touchstone mod has a blue led on it for
testing purposes, It will light up when the phone is on
the touchstone base, plugged into a usb cable, OR,
When running Andriod!! So.... Thats why i think our
phnes suck that battery down like mad. Something in
the andriod kernel is enabling Power Out (5v) through
the usb port on the phone. It may be very little current,
But still may cause our power issue...
So, Hopefully, This info can be of good use to the developers
