So I've just bought my iPhone 5s with iOS 7.1.2, moving from Android. I've noticed that my data toll has more than tripled (from around 300MB to 1.1GB monthly) without significant changes in my usage habits.
Strange things like Calendar using 30MB (I can't imagine calendar events as being BLOBs), Safari almost 500MB (no youtube or anything over 3G) and Facebook 250MB (auto-streaming disabled), while on android those three combined wouldn't have costed me more than 200MB. Again, I haven't changed my usage habits significantly. System services alone costed me more than 100MB (yes, I live in Argentina, 500MB is one of the typical allowances, and no, moving to SF is not an option right now)
My first question would be, do you know of a way to troubleshoot this issue?
I'm a bit hackerly, so my first approach is trying to sniff on my traffic to determine what kind of data my iPhone is so eagerly exchanging. How would you go about driving all internet traffic through a proxy (not just HTTP)? All 3G traffic?
Is it reasonable to assume that my iPhone has the same internet activity over WiFi and over 3G?
Is there anything else you'd advise me about this? Anyone else with the same problem?
