Thank you for the screenshot.

Troubleshooting Data Consumption:

A. Singling-Out this Data:

Anything particular about these days (i.e. online classes, Zoom meetings, data consumption)?

B. How Much Space is in Storage:

Looking in the storage of your iPhone, how much remains? Do you know what this data is?

C. Reset to Factory Settings:

If this cannot go through as intended, then reset your iPhone to factory settings as if you were to sell it. Perform as instructed here, including the backup creation and then iCloud log out.

If you disable your Cellular Data service, then this would not be occurring.

I'm able to look at usage from my router, and this phone is far and above any other devices on the network."

Thank you for the screenshot.

Troubleshooting DTR and TCP:

Something is grabbing all of this data. One or multiple devices. So, look in the Downloads folder. los, change the password of the network, and whatever device is doing this would no longer have access to it, and all this would stop.

"X" Did you ever get this resolved?

I am seeing a similar issue with my wife's devices (ipad / iphone) using ~100GB per night when charging and connected to WiFi.
