You’re saying even after restoring from iTunes (re downloading ios 11.1 and installing it on your iPhone X though iTunes), not restoring from any backup and using the phone, still gets the same battery life? EDIT - it depends on what apps you’ve used. Could you send the other half of your battery usage screen? Need to see what’s on the top. But to answer your question, that is awful battery life. My old iPhone 5s got better battery life!
