iPhone 12 Pro Max overheating issue

So I just got the new iPhone 12 Pro Max and it's an awesome phone. Today is my second day of using it and i've noticed that it is starting to get a bit hot just while scrolling through Facebook. I have seen a couple of posts about the iPhone 12/12 Pro heating up so I guess we can add the Pro Max to the list too.

I have checked the background app refresh and don't have any tabs open. I charge my phone on a Belkin 10W Wireless Charging Stand as well.

Any thoughts?
