Battery benefit from rooting?

[willenium_1217]

So I have finally made the decision to root my phone today. I have had the phone for 3 months. THe biggest reason is because for some strange reason, the last 2 weeks my battery has drained like crazy. More than usual. So the actual question here is what can I do to help my battery life after rooting. I have read about de-bloating and renaming the .apks. But does that help too?
