Has anyone noticed a drastic drop in battery life when using the Siri face w/ hear beat? My watch typically lasts all day with about 20-30% battery life still left when I put on my charger at night. Two days ago I updated to OS4 and decided to use check out the Siri face. Yesterday, I pulled my watch off the charger around 7:00 am, at around noon my watch was dead. This morning I pulled my watch off of my charger again around 7:00 am and by 9:00 my battery life was already down to 65%. I have since changed my face back to my photos face and the battery depletion has seemed to have slowed down, but still doesn't seem to be as stable as it was before updating. I am wondering if this isn't due to the update or the Siri face with the heart beat monitor constantly checking your heart rate.
