New updates installed, closed my SP4 an hour ago, came back to it piping hot (hottest its ever been) and battery down to 14% from 60%, not jumping the gun but I pray this was a fluke incident!!
Update: "Hot-bag" this morning which caused a 20% drop in battery during my 45min commute to work.
Update 2: this thing is an unstable mess! Not a day goes by without a crash, fan on high while idle, high temps and overall loopy behavior. Its like I've been thrown back into the 90's. Yay, I look forward to spending 5 hours resetting and reinstalling! Total POS! Skylake, Microsoft's shoddy hardware and undercooked OS are all to blame! What was supposed to be the best Surface has been my worst (I've owned SP, SP2, Surface 3 and SP4) BY FAR!
