I seem to be having the exact opposite results with juice defender. Here is my results with and without JuiceDefender Ultimate. I was on the extreme settings and customized for the right apps. Was using about 2 hours and 15 minutes of display. Took screen shots when they were both at 15%. Was fairly light on using it the past 2 days. Might just try the custom settings or maybe try liquid gingerbread again. It does really help when you don't have service tho.
