It's not uncommon for me to drive 320km in a day and take flights that Google Flights claims emits 579kg per leg. So I'd place 55kg from phones in the "fuck all" category even if I upgraded every year.
Like, I don't know your life, maybe you go to your family or important business meetings or something with these flights, but in any case none of this is going to be "fuck all" if we want to have any chance to stay under the +1.5°C (or even +2°C) bar.
