Anders_ASUSI can confirm this. I tested a while day without Facebook app and battery lasted very long.So far, what we can see regarding the battery draining is that it's facebook's system services (not the ones you can see in all apps) that's causing this and it happened with their latest update. It can be triggered by both Facebook and the FB Messenger app. Force stopping them may not be enough (we're not sure yet).
The most efficient way of making sure that those services are indeed killed, is to uninstall both facebook and messenger so they revert back to factory version.
We are aware that these version are old and that it might not be an alternative for some of you but I just wanted to keep you up to date as we continue our investigation in this matter. Hopefully we will have a better solution soon.

m4n15h.r4w4tI have had this apps upgrade but can't confirm better energy management.https://zentalk.asus.com/en/discussion/comment/49641#Comment_49641
Not jumping on the gun right now but I do see an improvement in the battery after yesterday's update of Facebook (262.0.0.34.117) and Messenger (255.0.0.14.126) app.

Now I've uninstall both (FB&msg} and check if it the way to fix battery bug.
But anyway still waiting for Asus fix.
