I used ~20mb last month. heremaps with offline - faster, less battery. carbonOS rom on my pixel w/ no trace of google anything. read news type sites only on the toilet or in bathtub, so that's on wifi. when I'm out and on the subway or whatever, I'm playing a korean learning game on my phone. don't have any social network stuff. That 20mb was mostly email headers, set to only fully download on wifi and I only opened a couple of those emails.

googling something does not take 60mb. as soon as you turned on data, a whole bunch of google's android crap and other apps started phoning home and sending the data they've been collecting on your phone at the expense of your battery life.
