Excessive Data Use By Email

[WPCentral Question]

I have posted this question in the 920 thread and got some advice that I implemented. At this point I have shut off almost everything and updated from 8.0 to 8.1. I now have data sense and have determined the culprit - GoDaddy Email. I had it checking for updates every 15 minutes due to it being a business email. In a 10 day period it has used 1.5 gigs.

Here is the kicker, I has a 900 prior to this 920 and had it set up the same way plus I had location turned on with a weather app running in background and live tile and in a one month period I never used more than 1.0 gig?

I am beginning to wonder if this phone has a defect of some nature, has anyone else experienced this issue?

Thanks for any input
