watchOS 7 Battery Drain

I updated my series 4 Apple Watch to WatchOS 7 today. I use my watch all day and usually have about 30% battery left when I go to bed and start changing. Today my phone got to 10% by 2:30 pm! Why is this drawing so quickly?

I had the same issue on my Apple Watch Series 4 after updating to iOS7. I tried shutting down background app refresh, and ensured sleep app and hand washing apps were off.


This didn't fix issue so I read on some other forums about repairing to your iPhone. So I did a reset on my watch. I restored using the same backup I just reset and today the problem seems to be gone. After a 2hour walk I have only went down 13% which is normal level. When I was running out of battery my watch was showing a 35% drop after my walk.


if restoring from the backup didn't work I was going to try setting up as new watch but obviously I didn't have to go that far.
