IPhone 5 data usage very high?

I own a iPhone 5 and my data usage is extremely high. It's typically around 6gb, before my iPhone 5 I had a 4 and everything was good until my 5 ate up my bill and costed me way more. Any suggestions on things I should disable?

Turn off your data roaming, and make sure when your indoors and if you got Wi-Fi, make sure your mobile data is off.

  • Why is the data usage on my iPhone so high? I can't figure out what I'm doing that is causing it to be so high. I've compared to family members who seem to use the same if not more than I do. I frequently make sure I have Wi-Fi on hoping this'll reduce it?
  • Why is my email usage so high on my iPhone 4? My iPhone email is using a LOT of my data. For example, I just switched to T-Mobile and after 1 day my usage is 120 MB with 106 of that being mail. I even have it set to not load images automatically and it is still very high. Any ideas? I do have 4 email accounts on it. WIth about 2 hours left in the day I've gotten 55 emails today.
  • Why is my data usage so high after switching to At&T? When I had my iPhone 4 with Verizon, I used roughly 300MB of data per month. I recently upgraded to the iPhone 5 and switched to AT&T. Yesterday, at the end of the FIRST DAY of the billing cycle, I checked my data usage --- 500MB! I was barely on the phone at all yesterday. I probably checked Facebook 3-4 times and refreshed my twitter feed a couple times as well. I get about 50 e-mails per day. Can anyone tell me why this is happening?
  • Why do I do this? I'm very very very tired yet I don't want to sleep? I want to sleep because I'm practically blinking and bobbing my head side to side like a drunken man but I just don't want to sleep. I watch tv or go on Facebook or play on my iPhone. And I'm starting to get dark circles. And as a guy I don't wear. Concealer or whatever
