Since switching from the iPhone 4 to the iPhone 5S, my data usage has significantly increased. I am 16 days into my billing cycle (ends on the 7) and have used 1.110 out of 2 GB of data. I called Verizon, they said that LTE is much faster- obviously. I haven't changed any of my networking habits. I used to get the 50% notification about 2-3 days before the billing cycle was up- LTE can't make that much of a difference. Why is my phone blowing through my data? Has any one else had this problem?
