That would make sense if you leave 3G/4G on. I'm not trying to dig into the weeds but if mobile data is off or set to sleep like your WiFi then you shouldn't have any usage during that period. If you set your WiFi to sleep then I would assume you have your mobile data setup to sleep as well. Too many variables to take into account..lol.
