Yes, I want to know the answer, myself. My excessive data usage did not begin until I upgraded to Gen5. When I was on Gen4, I only had 10gb of data per month and rarely ever reached that. But suddenly after upgrading to Gen5, data gets gobbled up like crazy. I use a Mac, and already had all my apps set to "manual update" so I could control data use, and had turned off iCloud as well. On my iphone, background refresh is turned off, and iCloud is deactivated as well. I have my browser preferences set so that video does not automatically play. Also, turned off telemetrics on both computer and phone to keep my applications from phoning home to the mother ship. And, I do not stay connected to the internet all the time. I have a wifi router, and turn wifi off when not sitting at my computer. No data leakage occurs when wifi is turned off. The one curious thing I did notice, when using Activity Monitor to figure out which applications were hogging the data: when I have my antivirus software turned on, simply having a web page open in the browser uses data at a rate of 1mb per minute. Actively browsing websites uses data at a much faster rate. When I turn off antiviris software, the data use drops off drastically. I have tried 3 different antivirus programs (Eset Cybersecurity, Bitdefender, and Kaspersky) with the same result. I had to take the step of keeping antivirus turned off most of the time, only activating it once every few days (just long enough to update the virus definitions and run a quick scan) then immediately turning it off again. BUT - this did not occur when I was on Gen4. I hate to keep turning my antivirus software off, but for now that's the only thing that's stopping the bleeding. I know the software isn't updating itself because I already set updates to "manual".

I am having the exact same problem. I hope someone supplies an answer soon. I upgraded from Gen4 with 10gb of data to Gen5 with 20gb of data. When I had Gen4, I rarely ever used the entire 10gb. But immediately after upgrading to Gen5 with 20gb of data, even though my internet habits had not changed, data was leaking like crazy. Even though I have twice as much data as before, I have been forced to decrease the amount of time spent online, so I won't run out of data. What is going on?
