Haven't really had it installed long enough here to notice, but my percentage hasn't gone down any more than it would normally in 3 hours or so. When using it previously on my 3G it had little to no effect on battery life, the phone itself was just slow. (I didn't jailbreak my 3G until after the iOS 4.0 update turned it to treacle)
