Thanks for this information … I’ll follow the issue in github.
Battery cunsumption in Android increase if Nextcloud Server not available.
Selv hosted Nextcloud Server available in local LAN/WLAN, Calendar sync only manual in DAVx5,
in Default Calender-APP Calendar Display and Update selected: Batteryusage=1%/h (is OK)
When WLAN in Device is off, or Accesspoint off, or Nextcloudserver off: Batteryusage=2.5%/h

Lineageos 17.1 without Googleapps with or without microG
DAVx5 excluded from Batteryoptimization or not.
Nextcloud Server hosted local and only accessible in local Network.
I have tried lots of setup combinations or calendar-app like etar
Increase of Batteryusage does not happen, if DAV Calendars completly disabled in Calendar-App.
@linuxdatenschutz From my personal experience even 1% per hour is too much. Normally DAVx5 does not take more than a few percenteges over the full day (maybe a little more when there is an initial sync after a new setup on the device). It could however be that - if the connections responses from the server take very long, that DAVx5 is then active for a longer time and maybe needs more power. Or maybe if something blocks DAVx5 and it retries it after that.
