Why is my brand new goophone s6 battery draining so fast

A

AC Question

New phone arrived Friday put the phone on charge for 7 hours + to charge fully. Went to bed and when I woke up the charge was fully depleted. Charged it up again on the Saturday with the same result. If it is a faulty battery I have to return it within 7 days so would like some thoughts on this as don't want to go through all the hassle of returning it back to China. Thanks in anticipation of a reply.
