iOS Jailbreak 6.1 battery drain?

I have looked around on the verge forums and couldn't find anything about this problem that I am having with battery life. I apologize if this is a re-post.

After jailbraking my iphone 5 last night I have noticed a sharp decrease in battery life. So far I have installed openSSH, Auxo, NCsettings, F.lux, Lorem, SwipeSelection, NoNewsIsGoodNews and BrowserChooser.

Do you think any of these tweaks would have a significant impact on battery life or is this all in my head and I am just using the phone more?
