I've been using Juice Defender/Ultimate Juice since I got my Captivate. It developed problems, and the log said to uninstall and reinstall, which I did - but I can't reinstall a functional program. The ASOP Helper App will not install, and JD is basically useless without it. I've e-mailed support, posted in their ridiculous excuse for a forum, and have been ignored. I really liked the program and wanted to continue to use it, but the total lack of developer support leaves me cold. Any suggestions? If you don't use it, do you manage your battery yourself, and what methods do you use?
