"The tech support guy said the drain happens becasue applications do not shut down properly."

Everyday this reason seems to make more and more sense to me.
I tried every single tip, trick, conditioning, charge cycling, charge method, re-calibration, reset type, and dance ritual to try improving the performance of my battery and still do not get good standby battery life.
I've narrowed down my experimentation to two standby states: minimum usage with phone radio on, and minimum usage with phone radio off. (minimum usage = lowest brightness, vibration off, alerts off, mute switch off, IR off, BT off, data off, time sync off, auto-off 15 sec, on-call dim 30 sec)
This is what I got (over 12 hour period):
Minimum Usage w/Phone On
1.67% per hour, which projects to 60 hours standby
Minimum Usage w/Phone Off
0.96% per hour, which projects to 104 hours standby
I have no idea what happens to that 0.96%/hour misterious loss. I know that PDA alone does use power. But I've never seen a pda run out of battery in 4 days after being left off. My LifeDrive went from 100% to 99% in one week after being left off in the drawer.
I have not been using the camera and did reset my unit prior to measurement.
Random applications running in the background without intent would explain this drain.
I hope the "fix" shows up soon.
