I just converted from the PC world. This evening, I am working with my new 15" MBP (Lion) importing pictures into Aperture. It's been just about 2 hours and my battery charge has gone from 95% down to 25%... Is this normal for a MBP? All of my images that I'm importing are on SD memory cards and I have an SDD instead of an HDD. I've been checking the system metrics and I'm not seeing really heavy CPU or disk drive use.. Am I missing something? Thanks folks!
