Basically, updated my iphone OS to 4.0 a while ago, and my battery life went from being able to go noncharge for several days with regular use to not even being able to get through a day with minimal use.

Like are there any batteries i could buy for it that have extended life? or are there certain ways or techniques to extend it?
for example one technique I've heard of is to only charge it when the phone dies for about 6 or 7 times.
