Huh, not really sure if I have a battery drain issue or not...
I flashed 1.9 over 1.8.4 just wiping cache and dalvik. When I left work yesterday (4pm), my transformer was at 100% battery. My wifi disconnect policy is to always stay connected. I went home and it stayed in its sleeve all night, connected to my wifi. This morning I'm at 75% after about 20mins use at the office, about 16.5 hrs on battery.
The 3 applications listed in battery stats are Cell Standby 54%, Bluetooth 25%, and WiFi 20%.
Typically, I don't think my battery would have drained down quite this far when similar situations have occurred.
I checked my mobile network settings and nothing is checked or enabled.
