[Q] Can the Xperia T battery be charged in LG-ND5520 dock?

Hi! I just bought the LG-ND5520 dock (Dual, for Micro USB and iPhone connectors), and when I connect my Xperia T it doesn't charge the battery at all.
In other side, it charges perfectly a LG Optimus Hub and a LG L7, I supposed because of the brand, but, doesn't it have to use an standard current to charge android phones? or is a problem with some Xperia configuration? or Sony personalization?
The dock only charges the phone, it doesn't use the connection for reading files or anything else, it uses Bluetooth for pairing, and that's why I would like to be able to charge the Xperia T when docked (BT really drain up the battery).
I've tried letting the Xperia plugged in for a while and the battery only goes down. When I plug it on the dock nothing pops up or sound, it looks like nothing is connected. I also would like to be able to program actions in the Smart Connect app, but it doesn't recognize the connection.

[Q] Pogo pin - capacitive charging potential

hi,
I've been wanting a phone that can do wireless charging for a while.
This leaves me with 2 options : pogo pins (Nexus one, HTC one X, Xpeira Z), or capacitive charging (palm touchstone)
Both are possible to mod in the back of the phone, but i need a way to get the power into the phone. Hence my quesition. Does anybody know what these 4 connection points in the attached image are used for. I'm hoping this is a USB connector, but I haven't found the time to measure it myself.
tia,

[Q] Charging dock with pc connection

I have two questions about charging dock:
1) Exist any charging dock for xperia z1 which I connect to USB and can use phone with computer while charging?
2) How about battery, if phone is in dock whole day and many times will be take out and put back - can this shorten xperia z1 battery life?

Quick charge 2.0

With qualcom quick change coming out, I'm wondering if it's possible to port the battery settings from the Z3 to work with our Z1's. Would it just be a case of copying from a Z3 rom or would it need tweaking? If at all possible.
