It's doing stuff in the background which uses the CPU which creates heat. Apple has official comments regarding iPhone heating up during new OS install. It's normal. Leave it in front of a fan for a few hours after an update if it bothers you or take it out of its case

We are cheering for a new update! The version 13.2.1
 
My X has been warming up since iOS 13 too. 3 different X pieces at that. Through all iOS 13 versions.
 
Yup, my 8 Plus has been warming up to the point where i noticed it. It stayed pretty cool on iOS 12.
