So I've isolated my reduced battery life issue in my new 2010 MBP to something with my data migration. Before using Migration Assistant I get 8 hours but as soon as I transfer my data, it's cut in half. So I would like to know who bought a 2010 MBP and has transferred data from an '08 MBP and STILL gets at least 7-8 hours. I'm wondering if I'm an isolated case, or if this could be the root problem to all those with poor battery. Thanks! P.S. I'm still trying to isolate what exactly is causing the problems. I think it's a piece of software because I tried transferring ONLY Applications and it cuts my battery down. Now I will try transfer just my data, and see if it's okay. If it is then I just have to manually reinstall my software. This has become a huge let down for my faith in Time Machine... it was so easy before this happened!
