I upgraded from my iPhone 4 to the iPhone 5 on May 2nd. Ever since then, I've had issues with the amount of data being used. I have a 2GB/month plan and at the very most used 1 GB (which was mainly due to streaming from the Tunein App on long road trips) with my iPhone 4. With my iPhone 5, I have used 66% of my data and I still have 16 days left in this billing cycle. I should note, I have not changed my usage habits from when I had the iPhone 4.
I use wifi while at home, every night.
I have disabled iCloud.
I only use Location Settings if I need to use GPS, which is maybe once/twice per month.
I use Spotify, but rarely stream (I only stream if I'm on wifi, and I only sync while using wifi).
Is this normal?
