Hello there!
Honnestly quite surprised this is not a top priority considering the way most people use a note app on mobile (opening the app, writing a few things, locking your phone).
There are some messages here saying the team is “aware of capacitor background runner”, but does that mean this has been tried / implemented?
Capacitor docs stipulates that the task can run for up to 30 seconds. That seems enough for a lot of sync use-cases, despite the lack of control of “when” this happens. I figure that iOS may let the task run during a night charging my phone, for example?
There is also the “Silent push” path, that would wake up the app enough to allow some background tasks to run now and then. But for a lot of Obsidian users that actively use the app (probably the ones interested in background sync in the first place), their usage should tell iOS to allow for background tasks now and then.
I have a link about the ENTE devs that are using the silent push technic to make background sync work, despite users not opening the app very often, but I can’t add links to posts .
