dpham, I'm not sure what you're trying to get at. Thank you for providing this data, but honestly, as I've mentioned before, the turbo charging on this phone is capable of drawing 4 amps from the charger. I'm not sure what your background is, but as an electrical engineer, that is A LOT of power for a small device as a phone. Last night my phone reached 107.9 deg F turbo charging in just an idle state at home on WIFI and it was pulling 3.959 amps. In order to validate your statements of "my note 5 was cooler", you're going to need to provide the same data with the same tests on the note 5. If my hunch is right, I'm willing to say that samsung's fast charge isn't drawing as much current. It has a smaller battery, only 3000 mAh (20% smaller) so that will decrease the time that the charging stays in the "fast mode". And the shorter the time the phone stays in "fast mode" charging, the less heat that builds.
In the end, what I'm trying to say is, you're trying to make a comparison that is not apples to apples. I've looked for the charging specs for the note 5, but I can't find them, but my gut is telling me that it just doesn't pull the same amount of current. If you're that worried about the heat, don't use the turbo charger, buy yourself a couple anker chargers that will still provide a good amount of current to keep up with the heavy loads of navigation, hotspot, etc.
