iOS 7 iPod Touch 5 drain issue

Hi

When ios 7 came out for iPod touch I installed it and the battery life was awesome.. I could have Bluetooth, location services and wifi etc as well as all the other goodies running and not have any battery issues at all

Yesterday I restored my iPod to test something and now my battery drains 1-3% every few minutes doing barely anything!

Any ideas on a fix?
