Anytime I use it for more than 30 min at a time the back of the phone feels extremely warm, borderline hot, to the touch. Is this sipposed to happen or is it malfunctioning? I don’t remember this ever happening with my 6 or 6S.
 
Depends on the ambient temperature. If it's warm outside, the phone will get hotter. Also charging while using it will make it hot.
 
There are way too many variables here to give you a definitive answer.

Ambient temperatures, usage, screen brightness, apps, software issues, etc.

Best bet is to try a restart or restore and see if it persists.

I’m only really experiencing this indoors in well air conditioned rooms of 70 degrees. It’s usually not plugged in when it overheats, I keep brightness at halfway and I only use a handful of light apps, don’t watch much video. 99% of my usage is Facebook scrolling and texting. Doesn’t seem right.
 
I don't usually recommend this, but kill every app. Figure out which one is frying your CPU.

If you don't want to do that, assume the Apple ones work fine (they probably should)

So whatever is causing it to overheat is damaging the phone?
 
If you are in doubt go see an Apple Store and speak to a support person to let them check out the phone. To me it sounds a bit as if there’s a piece of software out of control or user error.

Also be aware that devices heat up more on wireless chargers and when setting up a new phone when tons of data have to be copied on the new device.

I don’t wirelessly charge, or do you mean phones w wireless charging capability?
 
For what it's worth this happened on my 6S Plus. It happened regardless of ambient temp, iOS version, running apps, etc. The back casing behind the logic board would get very warm, borderline hot. That phone also chewed through batteries like no other.

I'd try to take it in and see what they say.
 
My X was notorious for getting really hot, usually when connected to CarPlay. The phone would get so hot CarPlay would disconnect and the phone would reboot. I would need to hold the phone to the AC vent to cool down, unplug and re-plug for CarPlay. iOS updates didn't address the problem either. The X was a beta-device I feel like...horrible LTE & WiFi connection, poor call quality, overheating during CarPlay, Battery Health went from 100% to 92% in 6 months...at least this is what I experienced with my X, not saying all X's are like this, but it was for me.

Upgraded to the XS Max and never had a single issue as I did with the X.
