Just wanted to see if the recent faster battery drain on my new 2011 15" MBP could be due to anyone of the following:

1. Updated my 5400 RPM hard drive to a 7200 RPM hard drive (used same brand/Seagate).
2. Upgraded RAM from 4 GB to 8 GB.
3. Running Windows 7 thru Parallels 6.0.
4. Recent update to OS X 10.6.8.

Would any of these affect/drain the battery faster than normal. When I had the 5400 RPM hard drive I could get at least 7-8 hours of battery life. Now with the 7200 RPM hard drive I only get about 4-6 hours of battery life after a full charge. Any input would be deeply appreciated.

May God Bless!

I have everything that you've listed on my MBP 13. I think it's 1 and 3.

You nailed it. As soon as I removed Windows 7 from Parallels 6.0 the battery indicator shot from 2:15 to 7:07. I can't believe Windows 7 is that much of a battery hog? I will re-install same thru bootcamp this time.

Thanks!

MY MBP 13" is also running hotter on 10.6.8 and my battery life decreased dramatically right after update.

It's not windows 7 per se, it's running a virtual machine. If I launch VMWare, my battery life drops significantly too, regardless of the virtualized OS I launch.
