This issue has been posted before, but I’ve checked some of the previous posts and still over a year later the app on iOS and iPadOS is still draining our batteries in record time.
I opened up my app less than 30 minutes ago and watched my fully charged battery drop nearly 10%. In another 30 minutes it will drop another 10%. And I’m not even using the app. I’m just letting it run in the background so I can mute commercials occasionally.
