"sleep will drain the battery FAR, FAR faster than when it is turned off."
in my experience (I first bought my touch, over a year ago now), this statement is INCORRECT.
my ipod stays in sleep mode 99% of the time, and i do not notice a battery drain because of this.
there are several occasions when I do notice significant battery drain
1. when I listen to a three and a half hour radio show using wi-fi (i.e. constant use of wi-fi - unlike some suggestions, i don't find that having the wi-fi connected all the time drains the battery significantly, unless i go out of my wi-fi zone and my ipod is then continually searching for a network).
2. when i watch long videos (or several shorter videos)
3. when i play 'heavy-duty' games (i.e. ones which use a lot of graphics - generally the more expensive ones with larger memory.)
granted, in my normal every-day life i will probably connect my ipod to either my computer/docking station at least once during the day, so it does get regular charging. i don't worry about this particularly, because (also according to many articles), unlike the older ipods, the batteries in these newer models are a different type, and actually BENEFIT from regular charging.
but when i've been away from home, for example when i stayed at my grandmas for a couple of weeks last year, where i had no wi-fi access, i had wi-fi turned off, and thus didn't use it, and i only really used it to listen to audiobooks/podcasts before bed, and maybe a couple of basic games during the day, the battery lasted at least a week before it require charging.
i've also never bothered much about 'stopping' music. i just pause it, exit the app and go and do whatever else it is i want to do.
these are my experiences and things i've learned from reading around the internet. which i did because my original iPod mini's battery died because i left it plugged into a docking station for long periods of time.
hope this helps.
