Hi, I've been considering the XR, but whenever I play with it at the Apple Store. I noticed it's fairly hot to the touch in the bottom part of the phone/display. I realise that it being in the charger all day, with the background video running can be intense, but the other phones aren't as warm (or not at all). How's it like in day to day use? Games, videos, using the camera, browsing the internet etc.
