So with consumer reports abysmal tests, and all the bias on the forums, has anyone else not been able to get over 6 hours of battery life? I did a test, I brought my brightness to 25%, closed all my programs except itunes to play music (at low volume), restarted to clear everything up, and went about my day. After 5 hours, the computer was at 10%. I did everything apple suggested, did all their diagnostics, and I am still only getting on average 3 hours of battery life. Is there any chance that my batteries are flawed somehow?
