Are there any currently known issues with devices using far more data than usual? I have an iPhone 5, I have made sure to disable background app refresh, location services, wifi assist etc has all been configured to use less data. I have not been using any new apps and did not need to change these settings previously but all of a sudden I am seeing data usage that is much higher and at times I KNOW I was not using my phone or DEFINITELY connected to wifi.
Is there anyway I can see which apps have started using more data?
