I exchanged my Note 7 this morning. On the drive home I connected the Edge to my car charger, a Motorola OEM charger that I've used for years since my Droid days. I found the Edge to be getting very hot, really hot,..... The Moto is not an adaptive charger. I'm now charging the Edge on the Samsung wireless Fast Charger that I used with the Note. I'd say that the phone is just a few degrees warmer than the desk the charger is sitting on. Maybe these phones need the adaptive charger to keep cool. BTW what app are you using in your screen shots?
