Ipod Touch 6 Gen battery draining FAST

I just purchased and received my new ipod touch generation 6 and have only used it 1 times since receiving on Tuesday. I have turned off the wifi and it was last charged Tuesday night. This morning(Thursday) the thing was totally dead. If I am not using it for anything, why is it dying so fast? This is ridiculous for it to drain in 24 hours. I used it for 20 minutes Wednesday morning and then turned it off. This morning, nothing, nada. this is the 2nd time it has drained since I received it. The help section on saving battery does not help, because again I haven't used it for anything other than that 20 minutes. Shouldn't the battery live longer than that if not being used?
