I've found that switching Airplane Mode on will extend the battery life.
This switches off the wifi and bluetooth on an iPod Touch (although my
bluetooth is already switched off anyway). A fair amount of Googling
seems to confirm that iOS4 leaves wifi switched on when you put the iPod
to sleep - and this is very likely the cause of the battery drain. My
iPod used to last 2-3 days on one charge but I have been charging it
daily since the upgrade. I now leave my Touch on the Settings panel when
I put it to sleep, so I can easily disable Airplane Mode again when I
switch my iPod back on again. Lets hope there's an update soon so that
leaving wifi on is an option and not the default.

Hello,
iOS4 is now running on my iPod touch 2G - it doesn't crash, WiFi works fine but
everything feels sluggish, like wading through treacle. The threaded email is
very handy and the folders are brilliant, but not at the cost of making what
was a really nice experience into something irritating.
Is it possible to reinstall iPhone OS V3.1.3 onto my iPod touch if I restore
from one of the backups that iTunes makes every time I connect that was saved
before I installed iOS4?
Here's hoping - or even better, Apple pull a speedy rabbit out of the hat!
Cheers,
Stephen
