I have a late 2010 11" MBA (1.6 C2D, 4GB, 128GB). I installed ML yesterday when it came out. I actually did a clean install by making a USB boot disk. Since upgrading, I've noticed the battery life is extremely poor. It's losing about 1-2% every minute with nothing running other than Chrome. As I've been typing this message, it's gone from 87% to 84%. Activity monitor shows 97% idle. Has anyone else been experiencing this? I'm about to do another clean install to see if it fixes it since at this rate, the battery won't even last an hour. For reference, with Lion, I could get between 4 and 6 hours with web use. Now at 82%.
