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.
Thank you, that clears it up. I’m not as informed on this matter as I used to be in the past, apologies for any assumptions I might have made.
Thanks for the link and the link to the PR, I might try this with a PC or two in time. Do I need Intel Audio for Pipewire to work? I didn’t quite grasp the ramifications of certain parts of the firmware not working such as Audio and Sleep; would I need to find a software solution for Sleep? Also, will this affect C-states by any chance?
That makes a lot of sense. Maybe I was looking at something different in my network at that point. Thanks again!
No worries, I only about this stuff because I recently saw a Defcon talk about it on youtube and started Googling. I could be wrong about some of it to be honest, there’s a lot of uncertainty here.
If you use the headphone jack of your PC or a laptop’s integrated speakers: yes. If you don’t care, not really. You can always make a backup of the ROM chip first so you can restore it if you find any problems.
That depends. Some motherboards still have firmware for S3 sleep, that should work just fine I believe. S0ix is a bit weird in that it “sleeps” the same way your smartphone does, waking up occasionally to do things like download updates or do other background tasks. Quite useful for PCs left in sleep mode overnight, not great when the drivers are bugged and tell your laptop’s CPU to wake up in your backpack.
I don’t think so, but I’m not sure.
Thanks. I was planning to use a USB connection to a DAC for audio, but I’d like to be able to use the speakers on my monitor too, if possible. I’ll be using a desktop computer.
