@nate2014jatc Maybe you could ask in the Nextcloud forum. As far as I know, issues are better for reporting bugs than asking questions, and it will take longer to get an answer.
Batteryconsumption if Nextcloud not available
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.
- The Batteryconsumption i wrote (1% and 2.5%) is measured device overall.
- In manual Update setup, and no update manual started, there should be no answering time Form Server.
