Check the white arrows at the top. As long as they are greyed, it should not effect battery. That email check that you are running may leave the connection in a state that continues to transmit. Arrows stay white. That will drain your battery like mad.

Using either Advanced Config or Diamond Tweak (I don't remember which has the option), you can set the Data Connection to disconnect after a period of inactivity. My device is set to disconnect after one minute. With the same settings as you, I have from 85% to 90% battery remaining after 10 hours. May be worth a try.

Solid advice, I do the exact same thing.
