I have an app, which drains my battery if left on background usage "unrestricted". On "optimized" it's fine. But, somehow it changes back to unrestricted once a day - how is this possible? App is not getting updates, so not on update. Can it do it on its own? I'm not doing this - I'm just switching back to "optimized" over, and over again. No other app has this issue.
The app is Whoop (com.whoop.android).
