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.

How do you deal with this? Or are you using iPhone or something else?
I don’t ☹️
There is a hidden LocationServices system app from Qualcomm that proxies the communication on some devices - however removing this causes a bootloop from what I’ve read, and would prevent Android from being able to identify your location even if it didn’t cause a bootloop.
I use a Fairphone 3 though with a bunch of Google services in the stock OS disabled, so I’ve settled for just keeping my location data out of Google’s hands
Edit: add info
Is this document for every Qualcomm device? I’d be interested to remove such calls from my system if possible, but I’m no systems expert, and unlike the other commenter I don’t think I’ll be able to decompile Qualcomm’s platform service just to remove a few system calls.
Just decompile Qualcomm’s platform service and stub out the right system calls!
“Just”
You get pretty good at it after you do a couple. I also came up with a way to manually start a platform service with strace and a custom SELinux context, but that was a few years ago and I left all of that work with my previous employer.
I actually wanted to get a Fairphone 3 because of headphone jack but I got really good deal on a Fairphone 4 so I took it instead.
