Installed SetCPU and found out Aurora running in governor Performance which is making CPU run at 1ghz all the time even in sleep mode. Changing CPU governor to OnDemand (min 600 max 1ghz), or Fantasy will allow cpu to go deep sleep and I guess it should save some battery in standby mode. Also here are a few tweaks for build.prop
* '4' will do "wait for interrupt", no change in arm11's clock or voltage
* '3' will do "wait for interrupt and ramp clock", the arm11's clock is lowered to 20MHz instead of 300-500, and voltage is lowered too.
* '2' will do "app sleep", arm11 is still on, but put into low power mode (registers are still saved)
* '1' and '0' will totally power off the arm11 (so we have to restore registers and things ourself), don't know the differences between them
pm.sleep_mode=0 -> Power Collapse Suspend
pm.sleep_mode=1 -> Power Collapse (Provides best power savings)
pm.sleep_mode=2 -> Apps Sleep
pm.sleep_mode=3 -> Slow Clock and Wait for Interrupt
pm.sleep_mode=4 -> Wait for Interrupt
