looking at your htop outut in the first post and comparing it to my device for the one day period. I must say these are your rouge processes:

lib/gconf2...
sbin/lcd...
sbin/ohmnd
sbin/cad

the main culprit though is:

/bin/dbus -daemon

it's freaking rouge man! what the hell @.@....how many apps do you have running in the background? try to reduce em the two other culprits are gconf2 & lcd.

You can tell by looking at the "time" area of htop, that they are up & running for too freaking long, thus causing your cpu to wake up and drain your battery, it's also the reason why your device is hardly ever in C4 state.....something(s) seems to keep these processes active by calling em constantly, thus keeping your cpu awake/active most of the time.
