I haven't done any official timed testing or anything, but find that my extended battery lasts twice as long as the regular battery. I have found it most useful to leave the regular battery in the cradle charger so that it is ready to be used as a backup when it comes time to charge my extended battery. That is all I rely on the standard battery for. I then replace it with the recharged extended battery even if it hasn't run down completely.
