As a long time iOS user, I now mainly run Graphene + GadgetBridge with a helio strap. Pretty nice and private setup.

My running watch is from a chinese company that I do not trust, so I lock down the permissions quite far. I like that Graphene lets me control the network permission and have offline maps that cannot report anything external.

Overall the most annoying thing is not being able to iMessage... I moved who I could over to signal.

Also the battery life is amazing because I keept restricting apps from background usage and the defaults already do a good job of that
