[Nook Touch General] Bobby55:
Okay, I didn't build the level shifter to use uart yet, but I found out that the Fuel Gauge needs to be powered only certain moments. If the device loaded, I can power it directly, excluding the gauge from circuit. So, I installed a switch to power it temporary and then it resolved current leakage problem. Unfortunately, after a long sleep it also uses the gauge, and I guess the charger daemon does it.

Here is my init.rc:
