Hi, recently i found that my SII drain battery in standby mode

I always disable 3G, WIFI and close all the app before sleep, last time with this i will lose maybe 1%-3% only after 6~8 hours. But now i will lose about 6% - 8% in same situation.

Sometime in daily normal use, with 3G/WIFI enabled, it will drain 5% in just one hour without turn on the screen within this period (this case not always happen, but i really no idea why i will lose 5% in just one hour in standby mode. No active app in Task Manager)

In both cases, I try check on BatteryUsage and BetterBattaryStat but i found no wakelock, cpuspy also show that deepsleep is normal.

I'm using Litening rom 6.1 with Siyah kernel (ver. always updated)

This problem already annoying me two weeks and I still have no idea where is the problem. Can anyone help me about this?


P.S sorry for my poor english
