Possible battery drain on Wear OS after closing

Listing this as possible as I have been trying to identify the source of strange battery drain on my Wear OS watch. I am currently on version 20190504 beta.

After a recent restart, the battery life was good throughout the day, I then used sleep as android overnight and the next morning my battery drain was higher. At lunchtime the following day I force stopped the wear os app and my battery drain returned to the levels of the previous day.

I have been noticing strange battery results since around mid-April. I will continue to monitor this, but raising this in case it can be investigated to check that the app is properly exiting after sleep tracking is stopped on the watch.

Any update on investigating this issue?
