I have two older teenagers. They got a phone when they were 14-ish, fist year of French collège (mid school). We had conversations and whatnot and there were times when they were giving the phones to us so that they are not distracted when working. These times are long gone and their phones grew into their palms it seems. The older one is 19 and when he has lots of work he manages to disconnect. I think that between 15 and 19 yo the battle is lost and I gave up. I preferred to keep a close link and contact with them rather than fight all the time. There are probably better parents though, more strict and systematic. I am not without fault as I use my phone all the time as well.
