SERIOUS battery drain after 2.2.2 and os3 beta

[entei5000]

so since updating to watch is 2.2.2 my battery drain has been off the charts,,,

I take my watch off at 9am and back on at 12am, I usually end the day with 50%

Since the update, my battery drain is down to less than 10% yesterday it's completely drained!!!

So then I updated to os3 beta and the problem still persists.

Any suggestions? What could be the possible reasons? Background app refresh?

Do you by chance has FB Messenger installed? I can go 2 days without charging my watch on 2.2.2, but I installed messenger and it was dying after 4 hours.
