Recently I noticed, my battery does not last more then 2-3 hours when not plugged in. When I got the Mac it was around 5 hours. Of course this is development usage, typically with Eclipse+Jetty+Browser+Airport+Adium+iTunes running.

I usually never shut down my Mac. Just close the lid. Also, it is plugged in round the clock except for maybe 5 hours daily. I googled around and got conflicting opinions on exactly how the charging patterns should be.
Any tips?
Also, it is Summer in India right now with temps going up to almost 35-38 C. Would it affect the charge?

Apple recommend 'calibrating' the battery once a month or so by letting it run down completely before recharging. Other than that, I'm not sure how usage patterns or temperature affect battery life.

<aside>
It always amazes me how bad battery technology is in general. If battery tech had kept up with CPU tech, for example, we'd likely have dime-sized batteries that last a lifetime.

Thanks Bear. Will try recalibration.
I came across http://www.apple.com/batteries/notebooks.html which made me wonder about the temperature.

don't plug it 24/7,

fully charge it then drain(5%), repeat this cycle always, this will exercise all cells of the battery and prolong its life.
