Hello everyone: I recently purchased the Samsung Epic and I am just getting acclimated to all that the phone can do. It is my intention to optimize this phone's potential as a tool for work. My biggest challenge right now is battery life. I have downloaded the app killer and I have killed several apps but the battery conitues to drain rapidly. I recently left the browser window open. Is this a major source of battery drain? How can I maximize my battery life without stripping my phone of many of its rapid recall tools?
