Weird processes

Hi there
I have a "13 2010 MBP with 10.7.1 Lion on it, and since the day I installed 10.7.0 (2 days after launch day) I've had a few problems.

Battery life is weirded out
Right now I only have a few apps open (safari,iTunes) Brightness on full, key lights on full (yes - I know these take a lot of battery), and it tell me MAXIMUM 3 hours remaining on full charge with NOTHING CPU intensive going on. This seems wrong..
Coconut battery says 86% battery life, and 21WATTS being used... How the heck is that happening with nothing significant open?


I have weird processes on
Constantly I have - 3 instances of ioreg running! ALL THE TIME! For the last 2 months!!! Restart doesn't help!.. What is ioreg? And how do I get to stop using a lot of my cpu? (always minimum 10 per instance, maximum 30 per instance)
Also randomly I get processes such as lsd and a few other randoms
WindowService or something like that has a habit of taking 10CPU once in a while

BTW I'm getting all this from istat pro

Do I have to reinstall lion? I would prefer not to.


Sorry if i sounded a little rude. Please help me out.. Im just a bit frustrated by the precesses

BTW I already read that battery tips thingy..... Didn't help much
Thanks
