I have an RF meter that’s beyond expectation (requires explanation too long here!). I cannot emphasize enough the impact of Bluetooth in this study. This study used an idle iphone with all 3 antennas on (cell, wifi, blue) clearly stated. In those other studies, it’s not stated. Many researchers seem oblivious to the distinctions. In this sitting idle case, it’s bluetooth. The others may be providing a little contribution. I have an older 4G iphone w/att to compare. More than happy to elaborate offline…..
