Alright, guys. This is a summary of the whole situation.
This build -10149- still has lots, and I mean LLOOTTSS of issues. The glance is in no way the reason for the battery drainage. It seems like something is running in the background ALL THE TIME. Try and put your phone face down at night (which disables Glance completely) and it can drain from 100% -> 0% in like 6 hours. Of course that only works after using the phone, because when you're done, something will not shut down completely and will keep on sucking your battery. I'm guessing it's a sync-type issue.
Hope any Tech Guru can confirm.
