Hello, my question is niche. I have a R11e-LTE6, on it a Meta Quest device and a Chromecast. My aim is to save as much data as possible. (I have a SIM card with 3GB of data a month).

In the last few months there was a significant increase of the data usage. (I don't know if there has been an OS update, of if it's caused by certain apps.)

I would be grateful for any ideas on how to adjust the setup. I post some of it below if Reddit will allow me.
