So I have a few days to return/swap my macbook as its still under the return policy. But my issue here is my battery life is awful. I'm at 89% now, half brightness, and its estimating 4 hours of battery life. All I have open is chrome (on intergrated graphics) and gfxcardstatus. That's it! Do you guys think I should try to return it for a new device before its too late? When I had the 2012 macbook and I first got it, it estimated 10 hours around this time, not 4. Nor is 4 even close to the advertised 8 hours. I have posted additional images/stat pics up at https://discussions.apple.com/message/24682078#24682078 I've also tried a smc reset and pram.
