Battery Life tracking

-

ever since upgraded lion, i've seen 2010 mbp take hit in battery life.

2010 mbp, i7, 8gb, 256gb ssd.

snow leopard, average 4.5-5.5 hours on battery
lion, seems 2.5-3.5 hours on battery

im trying monitor system best can see if process running cpu high. i'm not able find stands out. 'upgraded' sl , experiencing general sluggishness , high ram usage bunch of other people experiencing.

brother has 2011 mbp i5, 750gb claims averaging 7-8 hours battery consistently. did runs on integrated gpu 90% of time, whereas on discrete gpu 90% of time. difference account big disparity in both our battery life?

there software utility can install track battery cycles, show me drain times each cycle, , how juice left when recharged. looking quantify "battery life issues"
 

1) initial install results in bad life due indexing of spotlight , other things. should stop within day or two.

2) discrete graphics card uses more energy. search forums on info this. gfxcardstatus or need.

3)coconutbattery. google that, that. check health.

4) lion more cpu intensive due ui , stuff that. can still long hours, it's bit more demanding sl across board.
