Hey everyone, I just got a new rMB m7. I'm thoroughly impressed with the computer going from my 2013 13" rMBP. The new computer has been handling everything I've thrown at it. However, I'm having an issue with the battery I think. Apple advertises "up to 10 hours," which I don't expect getting. But I was anticipating getting around 7 or 8 hours with light usage. Since I've gotten it, I've had no charge last longer than 4 or 5 hours. I reset the SMC and have found no improvement. I'm doing a test cycle with half brightness only running Safari and it's estimating only a max of 6 hours. Is this what I should expect or should I take it to Apple for a new one?
