Fitbit App on Android kills phone battery

[SunsetRunner]

I'm opening a new thread as the previous one was marked as solved by the OP and could cause confusion for people watching this particular issue.

Galaxy S5 4G + ionic. Fitbit app has been functioning fine for about 3 weeks now but yesterday, the phone gave me half a day of battery life yesterday with usage stats at 29% for the Fitibit app. I normally get a day and the next morning at least. Next one down was the screen at 8%! When I pay $400 (NZ), why do I have to disable features in order to improve performance like Fitbit is suggesting we do? Doing this doesn't improve battery life anyway.

Uninstalled until fix released.

No new apps installed.
After Fitbit uninstall, battery performance returned to normal

Having the same issue with an ionic on Original Google Pixel. 39% of my usage today.
