My Iphone 6s used 128. MB data when phone was off at 2 in the afternoon while driving home from work. My usual data use on that phone is less than 1. MB per day

It could have been many things. Most likely though some sort of update or background data from an app left open. If you want to prevent this you can prevent apps from using background data, prevent updates via data, or just turn of your data when you're not using it.

Was the phone asleep or like powered-off off?

Asleep. I have since turned off automatic update. Was that the right thing to do?

Yes turn off automatic updates.

For iphones, unless the phone is plugged in, the phone will turn off wifi while it is asleep to conserve power too.  Though 128mb in one afternoon is a lot of data.
