I have received this computer and the battery life should be 8 or 9 hours and it is more like 2 hours if you are running multiple applications. Very very unimpressed considering the fact that I spent $1,300 on a 2015 computer that is supposed to be fully renewed. And on top of that the operating system also will not update past 10.13 when the newest version out is 10.14.6 and the apple website even claims that this year and model can run it but every time I go to update it fails. Ive tried everything, and since it won't update I can't even download iMovie, when the main reason I bought this computer was to edit videos.
