Hello,I just got my MacBook Pro today (build date 10.30.2017) came with high Sierra and charged my battery from %40 to %80 for the first time but after I unplugged the charger cable the battery dropped to %74 in 2-3mins.The device is very hot checked with coconut battery shows 36.4c. and it says %70.I wonder if this this is a bug with the high Sierra or I have defective unit?
