the guy sold me my Desire also told me the same thing - charge 8 hours at the first time. But even though you plug in the charger for 8 hours, the phone will not be charged for 8 hours coz after the battery is fully charged, the charging will automatically stop. It can be verified by the cool charger which is not charging anymore after the phone is fully charged.

Anyway, I leave my Desire for overnight charge for the first charge. But like mode893 mentioned - fully charge and discharge the battery initially for 4 or 5 times will "condition" the battery to give the optimum battery life. My Desire (about 3 weeks now) can last me up to 2 days compared to max 1 day when it was new.
