For those who just updated their Watches, be advised that for the next 48 hours or so after the update battery drain is worse than normal as various background tasks (normal post-update tasks) finish working; your battery life should return to normal after those 48 hours. This is normal, and occurs with Android watches, phones, and all tablets. It’s normal and not an OS or watch defect
