battery comments:
1. wifi
no..wifi does not help... logically, having two radios working is less efficient that having one radio working

so turn it off unless you want it on...
2. poor coverage
clearly attempted connect/reconnect/roaming cycles are the death of a battery.. if you are in poor reception area ..set to home only (since you cant force raoming), or even turn the radio off and have wifi on..
3. apps
your choice of apps will dramatically affect your battery.... constant polling, inelegant or silly apps that constantly use resources are all your choice.... by example..when i put beejive on my 8330 it took a whole day OFF my battery life... IM+ was far far better...
btw.. pls explain why anyone needs a phone that can last 24hrs..... i need 16-18hrs, which the bold does just fine..
for it to be any better than that i need it to last two work days ..essentially 40hrs (which the curve could do).
