Huge battery drain (80% down in 3h). Never seen anything like that ever. Phone was quite warm. Rebooting didn’t make a difference. Kept using the phone in battery saving mode until I had access to a charger and now after charging things are back to normal.

I was trying to update my AW too right before I left the house this morning and had to leave at the verification step. I wonder if there was some process related to that that was hanging and caused the battery drain. Also, I was sitting in a bus in a sunny environment (south Vietnam) so screen brightness might have been dimed and could have played a role.
