Aluminum macbook battery?

I have had my macbook for about 3 weeks now, I admit I have not used it in a continual long stretch at all yet but it has been charged at least 10x by now. I charged it up last night to 100% and set about using it today. I got just over 1hr 50mins of use before the reserve power message. I literally did nothing but chat with one person on gchat wirelessly for the 1hr 50min or so. I did not surf any webpages or anything intensive.

To me that battery life seems pretty poor....anything I can do about it? Its frustrating that it takes longer to charge than discharge...

 

Did you have the back lite on full? That will kill the battery. Did you calibrate it?

 

Back light on about 75%, not calibrated no...the battery you mean?

 

Have you set the power management to 'better battery'?

 

Download iStat and check your battery health.and yes,he meant battery.

 

Where is power management in the OS? All I see is energy saver preferences, which does not let me select something as in Windows Power Management.

 

Right top corner, click on the battery sign.

 

well yeah, I have done that....that is "energy saver"....I dont see anything about setting it to "better battery" though...

 

oh well I mixed up some terms. "energy saver" is the one.

you can set some preferences in the system preferences panel.

 

1 hour 50 min does seem a little low, but still believable. I think the main issue is with the screen which draws the most power. If you lower your brightness, you should see a significant change.

 

Regardless of screen brightness, , sub 2 hrs is way too low
either the battery has an issue (easily checked through istatpro or system probiler> Power)

or there is a rogue process keeping your CPU taxed continously (again easily checked via istatpro or activity monitor..) You CPU usage should hover between 1-10% when the system is idle
