This build of f.lux prefers to use notifications (you can turn off the Notification Center ones).
The screen settings we're changing only work when the screen is on but we have to be "ready" when you unlock your phone. We're working on a version that does quite a lot fewer wakeups.
In our jailbreak version, we just hook the screen unlock and do work then, but we can't do this in the jail because we never wake up.
In this version the notifications serve as a "wakeup". If we fail to show a notification, we hit the unlock instead.

The battery impact overall is extremely low.
