Ok here we go:...
Attached the new and working zip file
|com.spotify.music : AudioMix||10115||22m18s120ms||0.00||5h31m19.606s|
spotify is the most dominant wakelock, here you can see 5,3 hours...
All other user wake locks are a few minutes maximum, everything normal.
Here we have the kernel wake locks and I'm really proud of them, l2_hsic reduced from partly 10 hours to these beautiful values.
So your report seems to be really good to me, you simply have to optimize spotify.
