No probs , best of lucks ! <| sep |> Yup . It has a lowerwattage CPU and a bigger battery and no touch bar T 1 chip to power . It was obvious from the specs alone that there would be a significant realworld battery life discrepancy . Apple chose to mislead people into thinking they have the same battery life in marketing , apparently to upsell the more expensive touch bar model . I ' m disappointed by that move . <| sep |> game is over <| sep |> Ah okay .

Real world usability is much lower than the theoretical 4 MB maximum . See corecapacityincreasesfaq # segwitsize
