I have never owned a Mac so I'm not sure if these are regular battery results. After owning my MBP for about 3 weeks, the Coconut battery is down to 96%. I understand that's normal because it just fluctuates. But the battery performance is no where near what is advertised. I usually don't get over 5 house (advertised 10). And yes, I brown half brightness, and no mostly no flash ( i can't help ignoring flash ad's sometimes). I calibrated the battery twice... and right after calibration I took it off the charger and the time is shows is 4 hours left... this cannot be right. Do you guys think I should talk to Apple about this or will it eventually pan out that the 10 hour advertised battery life is actually more like 5 at most. Thanks in advance.
