I was using for a long time the rom from QTek with version 2.18. The reason that I sticked so long to this rom is because its efficiency with the battery. As soon I updated to a newer AKU rom I experienced the same problem, in standby it drains much more battery than this QTek rom. Normal a night it costs about 1%, with the newer roms is dropped as soon as 20%. I searched for a reason and finally I found it. I removed the SD card and I saw the problem solved. So there must be something with the SD Card. I searched in the registery and found that the power management function for the SD Card driver is disabled. This means the sd card is always enabled and at full function (= full power).

If you like to enable the power management function of this driver change this key in the registery

HKLM/Drivers/SDCARD/ClientDrivers/Class/SDMemory_Class/DisablePowerManagement change this value to 0. And try then.

I use now WM6 and changed this value, now it is using less battery than the qtek rom.

Without this setting I was able to user Crossbow and newer AKU roms for MAX 48 hours. Normal (and now) it is 4 ~ 5 days or even more if I keep it more standby

Please tell me if this also works for you.
