I noticed on my new S8 that when playing games it no longer gets hot like my S7 does. I keep Pokemon go open while driving to work each day. (I know I am about the only one that still plays it.. LOL) On the S7 with about 50% brightness in a 20 to 30 minute drive it would be blazing hot. On my S8 on the way in this morning with around the same 50% screen brightness it was just warm. They are not in identical cases (S7 in Spigen Neo Hybrid) (S8 in Spigen Tough Armor) but its good that its running cooler than the S7 by quite a few degrees. I know heat and electronics are not good for them in the long run so this is a good change. Lets hope the Note 8 runs just as cool as the S8 does.
