Help Turning off Background data and Auto-Sync?

[Cbelflower321]

I was wondering what are the pros and cons of turning off the background data and auto sync? I mean does it really improve battery life that much?

I am tiring it out, ill let you know in a day or two.
In my option I don't think it will make that big of a difference, I think turning down the screen brightness is what makes the biggest difference, especially if your on it contently.
