I run SPB Mobile Shell and SPB Pocket Plus in the background, and that's about it for what's always running. My wife, meanwhile, gets amazing battery life. Maybe I should try changing to manual-only for my e-mail and see how big a difference it makes. Then again, I get my extended battery back today, and that always did much better for me.

Actually, what is probably killing it is the "sip off my computer's power throughout the day" bit. With a complex power-drain device like the Titan, battery usage can vary widely and have all sorts of unpredictable effects on the Li-On that you may not find on simpler constant-drain devices. Also, as someone else mentioned in this thread already, "battery performace is reduced as heat goes up, also the "meter" calculates bases on a drain history."
Constantly charging the battery is actually bad, since it creates extra heat and messes up the meter and charging guages, not just the "history-based" one you see on the screen, but even the internal one that tells the battery when to stop charging. The end result is that the charger may not be stopping at the proper point- either overcharging or undercharging, both of which are bad.
The one thing that I noticed makes the biggest difference as far as battery life (and my theory was later confirmed by an electrical engineer), is to actually leave it OFF the charger until I'm ready to leave it for a complete charge. That means don't plug it in the car to top off on your way to work, and don't take it on/off the charger periodically. I leave it until I'm ready to charge it up fully, and like this my battery easily lasts a day and a half.
I only charge my phone when I sleep now, and if I forget to, its still got enough juice for most of the day when I wake up. This is with push mail via exchange, and EVDO coverage.
