This is really weird! After resetting all statistics I got this:

- BatteryUsage.jpg (111.21 KiB) Viewed 24463 times
So out of 13 1/2 hours on Battery AutoMagic kept my phone awake for nearly 5 hours!
The total combined running time of all my flows in that time was only around 20 minutes, and most of that time were Sleep actions (with deep sleep).
So what is using the battery?
BetterBetteryStats doesn't reveal anything (to me) and Wakelock Detector does not (yet) work on KitKat, though I'm working on it.
Nexus 4 with KitKat, AutoMagic 1.20 dev. No new flows added for a while.
