3 hours in the background seems a lot to me.
I started the app clean and configured it from the start (it was a pain in the ass because I migrated my settings from Sync for Reddit lol) and the issue still remains, having this huge background usage prevents my phone from going to deep sleep properly which lends to a bigger battery drain.
EDIT: BTW the issue is gone when I set the app to restricted battery mode instead of optimized… But I’d rather keep it in optimized as it closes less often in the background, that is how I had it with Sync for Reddit, which on average its active background was several minutes only.
EDIT 2:
This is the process that Battery Guru/BBS says shows
job/io.syncapps.lemmy_sync/androidx.work.impl.background.systemjob.SystemJobService#9188
It is not that Sync drains too much battery, what is going is that hinders the phone to go to deep sleep which lends to a bigger battery drain, usually my device drains less than .60%/hr without background activity on my part, with Sync for Lemmy with the optimized profile it is always above 1%
This seems like a possibility since I’m always using the AdAway rooted version…
Perhaps Tracker Control might help me to point out something odd there.
