I agree, I'm not worried about power savings per say, although power savings even with such a large battery is a good thing.
What I really like is turning BT on or off or WiFi on or off set the screen brightness, when needed.
Smart Actions allows you to set up you phone on schedule on the days you need it, kinda easy and fun but you gotta play with the settings.
Do you see the need to use Smart Actions and Juice Defender?
