sounds like a dying battery to me, i keep all services on, have 4 push email accounts, generally get around 3-4 hours usage/day according to iphone usage tab, and can generally last from 6am Monday till about 8pm Tuesday, with 1:00-1:30 'phone' time or less per day... under what I would hope, but acceptable,
OP's battery life: ****-poor bad, to speak frankly.
