My macbook pro used to have awesome batter life ~8 hrs or so. Then I updated to Lion because some of my software would no longer work without the update. Now, I am only seeing 2-3 hours of usage before having to plug in. All settings are the same. 50% screen brightness, not using super drive, just web browsing/office work. I checked the status of my battery and it says the health is normal and only 102 charging cycles. The only other thing I have done was shut off the computer. Press and hold control/option/shift/power button for ten seconds and then rebooted. I did not notice any change. Any suggestions appreciated!
