Hi i got my MacBook pro 15 inch with the touch bar yesterday from fedex so far i love the laptop a lot but there is one thing thats bothering me, im on the third cycle now or so but the battery from 100% to 0% seems to last only 2hours and 50 min to 3 hours for me i don't know why, i downloaded a app that tells me the estimated battery life remaining and it resembles what i'm seen anyone having this problem or do i need to get a replacement?
