I have been using My Data Manager to troubleshoot some unknown data usage on my iPhone and iPad. Both of these seem to be pulling between 700-900MB of WiFi data during the night at approximately 100MB per hour between the hours of midnight and 7 am. My Data Manager is showing this usage but when I try to determine what app is drawing all this data, all it tells me is "OS Services". I can tell you that my emails are all set to manually refresh so there should not be any email activity going on in the background. Although my iCloud backup is large, it shows as complete around midnight so that doesn't explain the data usage between midnight and 7am.
What else could be drawing such a large amount of WiFi data which is connected to "OS Services"?
Thanks for your help.
