I have a brand new MacBook Pro (early 2011 model), 15" high resolution anti-glare display, 2.2 GHz Intel Core i7 processor, 8 GB RAM, OS X 10.7 Lion. The battery life is abominable. Battery life: 120 minutes or less Test conditions: Full screen brightness (that might sink it), very low processor load (Gmail in Firefox, text editor, and Python interpreter), Bluetooth is off, Wifi is on. Hard disk rarely spins up, very little hard disk I/O. Is that normal battery life? This is even worse than the battery life on my 2008 MacBook Pro 15", and that one at least had a user-swappable battery. My father says his MacBook Pro 15" (2009 or 2010 model) gets up to 7 hours of battery life, and I can't see how my newer MBP could be doing so much worse than his. My questions: 1. How do your MBPs stack up? 2. Under what circumstances will the Genius Bar replace my battery? (I still have AppleCare, the computer is brand new.) 3. Should I do the test under different conditions? (This is a hassle, because the current "test" data is just from recording what happens after my normal use.) Thank you all.
