So I found a solution to the unimpressive battery time I've been recieving on my mid March MBP. I like many others was getting half the time I should be. It turns out after doing a fresh install WITHOUT migrating my data, I now get better battery performance. So something with migrating my preferences/files is causing the problem probably because I was migrating from a machine with different hardware ('08 unibody)so the preferences were conflicting or something... I'm no expert. So my question is, Apple told me to copy my data over without doing a data migration so I am wondering what is the best way to do this? How can I make sure all my data copies over? I'm scared I'll miss something by just dragging things over from Time Machine, and some programs don't seem to work when I do that. Does anyone have tips on the safest, easiest way to do this?
