I have turned my work iphone into a dumb phone. It has got only apps that cannot be removed, plus the apps that are provisioned through mdm. No icloud, nothing beyond what is needed for communication with my colleagues. Location services off, bluetootg is always off, wifi only connects to cirporate network. My personal phone is less so dumb but I follow the YAGNI principle there as well.
