I found quite the opposite.  My battery life went from ~16 hours to ~26 hours when 3.2010.02 hit.  It was the one noticeable change on the device from the update. :)  And yes, I have a very similar setup.  It's on wifi at home and work, and on 2.5G when not on Wifi.  I have the IM plugin enabled and am constantly on-line, do moderate web surfing at times (usually on wifi), and occasional mp3 playing.

I've also seen a major increase with the new over-clock kernels, which I tweaked and played with a bit.  The main set(s) have simple branches that are low voltage or ultra-low voltage.  Even if you don't overclock (Titan's kernels by default are the standard 250-600 range), just using the newer kernels can increase device life quite a bit.  Since I put in the lv kernel set (oc set to 250-900) I've been seeing average battery levels at 50% or so most nights, and have had an actual up-time of over 40 hours between charges a couple times now over weekend trips.

Personally I'm more surprised that these devices can last as long as they do on the battery they have.  Most people would love to get a few hours out of a laptop while web browsing.  Why do you expect a device with as much power as a laptop to last longer just because it has a GSM chip in it?  Admittedly, my last cell phone had an up time of 2 or 3 days between charges, but that's all it really did.  If I ran J2ME apps on it, that life cut down to a day or less quick.  I'm pleased as punch that I can IM, text, browse a bit, enter calendar items, etc, and still have any juice left at all at the end of the day. :)

Unless a newer firmware is available, don't upgrade to 3.2010.02-8. 

I have found since I upgraded my battery life has gone from 1 1/2 days to about 7-8 hours.

Hope that helps,
Bernard
