Coming from my 4S l, which I had since launch. I have never used more than 1gb in a single month on 3G. I am on wifi whenever and wherever possible (home, work, airports, hotels, etc.). I noticed that I somehow consumed 4gb since launch on my new 6 (rec'd 9/19). Is there background data or something else I should look for that is eating through my data? My browsing and usage habits have not changed when going from 4s to my 6. Any ideas would be appreciated. Thanks!
