How can I tell if it's stuck in perpetual sync mode other than battery drain?
petercreasey has given you some bad information.

Firstly, no-one has actually stated it, but the auto sync option not staying off is a bug in the firmware. Kobo know about it and it should be fixed in the next update. I don't know when that will be, but my guess is sometime in October.

Adding "PeriodicAutoSync=false" to the config file is a workaround. That is what the broken option would add if it was working. As long as you don't go to the sync page of the settings and change something, it will stay in the config file and prevent the auto sync from happening.

This does not stop other syncs from happening. If you press the sync tile, it will sync. If you open a purchased kepub, it will sync the status for that book. When you close the book, it will sync the status again.

Sometimes the sync doesn't complete. It will continue running and using the battery. This has absolutely nothing to do with the auto-sync. The only issue with that is if the auto-sync doesn't complete, it will use battery until you see it and stop it manually. I don't know why the sync fails to complete. Except maybe some network issues, and these I'm not sure on. I do know that on my previous problematic DSL service, it would fail to complete frequently. On my current connection, it fails a lot less often.

One of the things I do when the sync isn't happening is to open the browser. I do this to check the network is up. If I can't connect, then there are network problems. If I can, then I know it is either the sync or the Kobo server. Sometimes this does seem to wake the link and the sync finishes shortly afterwards.

Any sync should stop when you tap the sync tile or the option in the menu. But, sometimes that doesn't happen. Or the tile shows it has stopped, but the menu doesn't. If this happens, then none of the syncs will work from then on. It probably means a background task has become stuck and will probably keep running using CPU and hence battery. Restarting the device will fix this. There is no need to log out of the device.

With all this, Kobo doesn't expect anyone to do this. They want the devices to just work for everyone. But, unfortunately, there are bugs, as there are bugs in all software. This bug just happens to be a visible one that people here have latched onto as the cause of problems they are seeing. Adding the option to the config file is something I suggested when the bug with the option was raised. I suggested it as a way to work out if the auto-sync was the culprit for the battery drain being seen.
