I should add that I do use it for backups, it’s a great program, but I’ve only ever used it for one-way scheduled syncs.

I’ve sometimes found that it just stops syncing on one phone. And I did turn off battery management.

I need something that’s reliable.

I use resilio, but recently it used 20% battery in 6 hours overnight, when nothing needed syncing.

Is there any way for it to sync from desktop to Android immediately when a file changes on the PC?
