I regret that I didn’t do a detailed write up at the time, and that since I didn’t I only have some abstract anecdata to offer but for what it’s worth: A couple years ago I rooted Android (Planet Gemini), installed my own root CA, forced all network through USB-C —> ethernet, connected the ethernet to a physical network tap, and decrypted almost all the traffic. With only a handful of common apps installed the (idle state, no UI interaction) phone-home traffic and telemetry was non-stop. A majority of it was to Google, blocking it made the phone basically non-functional. There were also inexplicable calls to strange Chinese IP addresses that would only emerge every one or two weeks that I couldn’t hunt down the source of and Planet said they didn’t recognize. I want network activity to be 100% correlated with my UI interactions including updates. I feel power users should be given that right and option. Windows and macOS (and sadly Firefox) are also miles away from this but Android was ridiculous. I haven’t tested iOS but I assume it’s about the same.
