A:Answer Yes, I noticed the deerance, unlike my Gear Fit Pro2 that I have used in the past. My new Galaxy Fit2 not have 100% real time conectivity / updates. From time to time I recive "Band backed up" notice on my phone. So if your phone and Fit2 are seperated the Fit2 monitors, collects and maintains data. I don't know the logic sequest that are requied but the data is transfered to the phone post activity. Note: just a guess but maybe that heps with the unbelivable (7+ days) battery life.
