Your phone is still under warranty, including your battery. If you've tried removing Facebook (although I have Facebook installed with no issues) and still experience heavy battery drain go to an Apple Store or contact
Apple Support.
EDIT: Did Apple replace your battery or somebody else? If it wasn't Apple you've most likely killed your warranty.
