I upgraded to the iPhone 5s from the 4s. With the 4s I typically used about 0.5GB/2GB in a month. After a week of using my 5s I looked and saw that I used 0.7GB/2GB in that time! Is this normal? I'm on the latest upgrade, have my location services turned off, am rarely not on a wifi connection, my apps aren't downloading automatically, background refresh is turned off. I don't want to turn off cellular data when I'm out of wifi range because what would the point of having a smartphone be?
I am having the same exact problem! Basically shut everything off so now the phone works as an ipod touch that makes calls...
Did you ever get help on this?
Its only been 4 days and Im almost at my 2GB limit.
