I've heard others say that it eats battery, so you're not alone. When installing Facebook and Facebook Messenger, my Nexus 5 froze...the only time it has done so. I'm not saying it was because of Facebook, but it was odd. For that and other reasons I deactivated account and uninstalled.
If you put it in standby does it do the same my 1520 goes from up to 5 days down to 8 hours due to this, I uninstalled the messenger app wish it was native like 8 again
