I have been searching around to see if I can find a definitive answer to this question, but no one seems to answer it directly. I have 2 domains running Google Apps and my one GMail account so that means I have 3 accounts pushing GMail to my Droid. Only the GMail account pushes calendar and contacts though. Am I killing the battery by having 3 accounts push to the device or is push GMail battery friendly? I have seen a decline in battery life lately, but not sure exactly what is causing this. Thanks in advance.
