I'm on iOS 8 using an iPhone 6+. I've turned off all the instances of 'push' notifications I can find in settings and yet when I check my cellular data usage, it's shows 'push notifications' using cellular data. I'm stumped as to what push notifications I'm using. My mail is set to manually receieve and as far as I can tell, I don't have any push notifications turned on anywhere. I'm stumped. Anyone have any ideas? Thank you!
