If you've had your iPhone X for a while, you've probably got the settings set the way you want them. I thought so, also, but out of curiosity I read the following two articles and found some that I changed.
One setting in particular was aggravating to me: every time I touched my iPhone X the display woke up and consumed battery power. I didn't like or want that. Way too sensitive I thought. I found a tip in the second article on how to turn that feature off. It took me so long to get that setting set to my preference.
HERE and HERE are the two articles in case you'd like to review the settings in your iPhone X.
