24 hours of usage+stand-by. Basically if I believe what the phone told me today at around 6:30 PM, I should have gotten over 24 of battery life. Mind you I barely used my phone today. Barely went over an hour of OST.
There is definitely something wrong, and again it may or may not be "L".
Google has re-open the issue:

I'm glad I'm not the only one getting really crazy battery life throughout the day and then bam! - Misc crops up and starts killing the battery (or it appears to be doing so).
It's also possible this is a bug in Google Play Services.
This misc thing is completely wrecking me. I have to throw my charger in my bag on longer days now - never had this large an issue with KitKat unless the mm-qcamera-daemon came up, rare as that was. Problem will probably be obliterated by final. Or I pray it is, anyway, for the sake of my sanity.
