I’ve noticed that whenever I plug my iPhone XS it almost immediately gets significantly warmer. I don’t recall this being an issue with my X. — Is this happening to your phone as well?
mine no doesn't get warm while charging with ipad charger
That’s what I’m using as well. It’s the 12W iPad charger + an Anker cable. Same ones I used with my iPhone X and didn’t have any heat issues then.
Any idea what could be causing this?
