Just wanting to compare your rates if you use meterberry, I have a battery discharge rate of 8% an hour with my application free space hovering around 23 MB.

My phone has just been sitting in my leather pouch today at work. I haven't used it at all but my discharge rate is .6% per hour and my memory is at 37.6. I upgraded to OS .132 last night and shrunk it (Many thanks to Lyricidal). My memory started at 51 MB when I rebooted last night.
I also have that whack Batterybooster program but who knows if it helps or not. I've changed my OS so many times that I don't know what is going on but hey I'm doing better than you guys.
