If you didn't turn cellular off too, it will drain even if nothing else is running. Cellular is a HUGE user of battery as your phone is constantly working to remain connect to a network.
Do you happen to have connectivity issues as well? If so, your phone may use a lot of power trying to connect.
After iOS 18.1 update in iPhone 16 the battery is draining fast
