Is this supposed to be normal? I got my rMBP 4 days ago and at 100 % charge the time remaining is 3 hours?! I have AppleCare so I might take it in. Has anyone else experienced this? Specs: 15" Late 2013 rMBP 16gb/1tb/2.6 See attachment EDIT: Added extension click to flash and seems to be a lot better!
