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.
I found a few links summarising this:
Note sure if e/OS/ has taken as much care as Graphene has to make the requests more private. Then again, they don't claim to be the most private OS, just De-Googled.
Edit: this is also a good read for further attempts to make your device more private: https://grapheneos.org/faq#other-connections
