I think you should remove cydelete, it's not compatible with iOS 6. Have you tried a reboot and see if that changes anything? Try disabling your winterboard theme and see how that affects battery life.
Or you boot up your iPhone holding the volume up button. This will disable mobile substrate which is what all your tweaks should be running on. See if your battery life is still bad.
The reason why I tell you to use the phone without any tweaks enabled is because it might not be the tweaks itself, it could be that your phone is using GPS, it could be running apps, etc
By chance, are you using the app mailbox? I heard there's a battery bug with that app in one of the recent versions. If you are using mailbox, try uninstalling it and see what happens
The best thing is to reverse what you did when you noticed this battery drainage problem. Maybe it's a new app update, new cydia tweak update, etc
