JuiceDefender is the best app to extend battery hours. For example, when the screen goes to sleep, underclock the cpu. When wifi is on, turn off 4G and etc or turn off wifi when you leave your location (using mobile network to estimate your location).
For Greenify (purchased version), if you install Xposed Framework, you can disable apps like Facebook so it will only activate when notification is push to the phone.
BootManager (installed through Xposed Framework) - allows you to control what app is run on startup. Not much helpful here but if you reboot your phone often, it helps a bit.
LUX allows the phone to auto adjust the brightness further by allowing user to set a profile of brightness level.
