If your phone is actually switched off (Hold VOLUME UP and the right SIDE button until Slide to Power Off appears, and do so) then it won’t use any cellular data (or energy for anything else)
If you are just putting the phone to sleep by letting it time out or pressing just the Side button it will continue to try to connect to the cellular network. If you don’t want it to do this put the phone in Airplane Mode. You can then turn on Wi-Fi if it turned off with Airplane Mode.
