The top app is Facebook in Wakelock Detector. It's the main culprit but I have even disabled the Notifications from the FB app and also disabled it to autostart using AutoRun Manager + Greenify it whenever I don't use it.

Click to expand...
Click to collapse
Try deleting it and check if battery drain is still present
A day without fb is okay

I've tried Greenify and it doesn't work all that well. Facebook is one of the apps it just can't hibernate and it always starts up again.
I found a workaround though, but it depends on how intensly you depend on Facebook.
I installed an app called App Quarantine. It puts apps (even system ones) down to sleep without any chance of them starting up again without your consent. The thing is it's not as simple as with Greenify, since when you Quarantine an app, it dissappears from the phone. Icon, widgets, shortcuts, everything, it's like you don't have it installed.
The thing is you have to set a widget from App Quarantine for the app you quarantined and then the widget comes out in form on the app's icon, with a lock on it. If you want to use the app, you just click on the widget and then it comes back to life and opens. If you're done using the app, you click the icon-widget again and it locks it, and that's it.
I use it on the Facebook app and it doesn't come back on eating my battery, however the "downside" is that if you rely constantly on FB notifications and such, you won't get them since the app is quarantined. However I set my Facebook account up so that everytime I get a notification it sends me an email, so via email I'm still "getting my notificacions" even though the app is quarantined.
I guess it depends on everyone's usage of a determined app, but FOR ME it has gone well and saved me a lot of battery life since I've quarantined a bunch of apps that I just use or check a couple of times a day and that are major battery drainers if not controlled.
