So i've had my Macbook 2016 for about a month now. The battery have been the same ever since I got it, but it's not until now i'm starting to wonder if something is wrong because this can't be right... All i do is use safari and iTunes on my macbook. I've used my computer for about 1,5h - today and it's already down to 73%. It currently says I have about 4h battery time left. Not even when it has just hit 100% battery it ever say any battery time close to about 8h at least or anything. Is this just how it is for everyone?
