I found that after running SamuriHL's excellent script to update to .2233, .230, and now to .232, Juice Defender (I'm running Ultimate) loses its settings after the updates. This could account for faster battery drain reported by some users. I noticed that I updated, my battery drained almost 50% faster than when Juice Defender was tweaked out.
So, once you get Juice Defender set the way you like it, select "Backup" from its help screen, and then apply SamuriHL's script to update ICS. After the update has stabilized, do a Restore from Juice Defender's help screen.
