So I got Fairphone 4, with /e/ os, a couple of days ago. When I connected it to my NextDNS I saw that it was trying to connect to some weird addresses, like every 5-10 minutes. I searched Internet a bit and found out that it was something with snapdragon cpu and location services. I travel a lot and use Organic Maps for navigation, so location was enabled almost all day on the phone. I turned off location services and connections stopped, and everything was fine for a couple of days.
Today I came home, checked logs in NextDNS and saw that phone started doing the same connections almost constantly even with location turned off.
Can I do something about this, other than allowing these connections? These connections are probably so numerous because they are getting blocked. If I allowed them, phone would maybe call home once in a couple of hours. I would rather not allow them, but I don’t want 20% of battery to be eaten by this.
The Qualcomm chipset is making these requests, most likely for GPS almanac data (satellite positioning).
Older chipsets send these almanac requests to izatcloud.net, unencrypted, containing your IMEI. No idea if newer chipsets have improved things though.
