podcast shuts down after 10 minutes or perhaps bluetooth

[biketool]

I use the flatpak version of podcasts.

I modified:

/var/lib/flatpak/exports/share/applications/org.gnome.Podcasts.desktop

with

Exec=gnome-session-inhibit --inhibit /usr/bin/flatpak run --branch=stable --arch=aarch64 --command=gnome-podcasts org.gnome.Podcasts

The podcast, bluetooth, wifi, basically everything, still shuts down after 10 minutes.

I noticed that too with Gnome Podcasts (not flatpak, but from Manjaro repos). I think it has something to do with Podcasts being started as "gnome-podcasts --gapplication-service" when started with the desktop file. It doesn't seem to take the new exec command. If I start it by entering the exec command in the terminal, it works. I tried adding gnome-session-inhibit to other desktop files and that worked too.

Is it that the pinephone is set to go to standby after 10 min on battery?
I suppose we need to optimize audio apps to force keep-awake but minimize CPU and mostly use audio processor, especially when in locked mode.
This podcast app is something we need on the repos, it is one of the things(and battery life in stable kernel) keeping my pinephone from replacing my N900 and being my everyday device.
I put Panucci in the recommend apps(I use it on my N900, it is FOSS and I can compile it for current desktop Debian AMD64.)

I dont love flatpack or snap and prefer to stick with apt packages.
(edit)
I installed this on desktop and it is definitely a podcast specific app and not also an audiobook player like Panucci.
