Seriously, where is all my data going? My wife and I are on wifi 80% of the data and there's NO WAY we are going through 10GB of data in a month on the other 20% of the time that we are not on wifi. We have "background app refresh" and several other options to limit the amount of data usage. Even still, the GB seems to be flying out the window no matter what we do. We never seemed to use anywhere near this much data when we were with Sprint, and our habits have not really changed all that much.
