I did a forum search for ‘data counter’ and stumbled upon this post:
When I check the data counters on my JP2, I get 20GB down and up(!) within a few days. After resetting the counter it shows small bits of data going both ways every second.
No apps running, AAS deactivated.
When I disable WLAN and the phone is connected only via SIM card, the SIM card counter remains still.
Is this some kind of “keep-alive”? I borrow expression from the SIP sphere, as I don’t know, if such a thing even exists in the WLAN protocol.
Anyway, is this kind of normal and it is just not shown in other OSes? And therefore maybe should be filtered by the counter? (Or at least, there should be the option to do so?)
I recently checked again since I noticed that I was seeing up to 400GB a month in traffic on WLAN. If I enable only the mobile data it’s much less traffic. I have a limited plan and unless I’m doing a lot of socials (mastodon) I remain under 6GB a month.
