I was looking at my battery usage when I found this thing at the top of the list. Does anyone know what it is?

If you mean No Cell Coverage it means that your phone is not connected to a cellular network, but it keeps trying to connect, which uses a lot of energy.
I believe you are referring to the No Cell Coverage. That means your iPhone was searching for a Wi-Fi or cellular signal or being used in a low signal environment, and this affected your device's battery life.

Also here’s a tip, if you are going somewhere and you know there won’t be cell coverage, turn on Airplane Mode.
