Massive battery drainage

App version: F-Droid 2.7.1

Android version: 8.0

Device model: Sony Xperia

Environment: no auto-update enabled, no auto-download enabled


I have been using Antennapod for a while and now have some issues with extremely hgh battery drainage. I have around 200 podcast subsciptions but a lot of them are inactive, and I also have turned off automatic updates and automatic dowloads, so I only update and download twice a day manually. Still, the app is using tons of battery even when just listening to the podcasts offline.
I used to only have a couple of subscriptions and it never was an issue then - but since I don’t have any updates or auto-downloads enabled, why is it using so much battery all of a sudden?

As know one else has answered I just wanted to ask how you know it is AP that is draining the battery? Have you looked at Battery Usage under Device Care which lists the apps which use most battery?

Yes, it is. It is using more than 14 % per hour while just playing downloaded files, w/o anything enabled, no internet connection.
