Hi guys I have bought the new aluminum uni body macbook, in the specs they say that it could stay for 4-5 hours without charging, however in may daily use:

1) use eclipse and programming web applications
2) connected using wi-fi
3) listening to music

for now indexing for spotlight didn't finished yet, is that a possible reason ?

my battery survives approximately for 2 hours not more. is that normal ? is it bad ? could you give me some of your experiences ?

thanks.

Well, I use VMWare Fusion, running Ubuntu, and also running xCode and Interface builder. Always have a browser open, and do a lot of other stuff. But I think my battery lasts a little longer than that. I feel like it is at least 3-4 hours.

There are different settings you can use for the battery, that might extend your time. Maybe you have it at the extreme brightest and using up power faster.

actually now i am feeling it lasts longer than before, may be because its new; now it has passed around 2 hours and a half and I am still at 56%.

This is the third/fourth time that i charge the battery, however yesterday i charged it 100% and in the morning i turned it on, and it remained for only two hours. now It seems its staying more.

Generally you need to calibrate your battery on new macbooks to get the greatest usage out of them.

Why do you run Ubuntu on a Mac? I can kind of see running Windows, but Linux?

I just replaced the battery in my 2 year old MacBook Pro, after discovering that it held a charge for about an hour. Turns out that the way I've used it lately (plugged in almost always) is not good for maintaining battery capacity. Live and learn.

This page was helpful to me

http://www.apple.com/batteries/notebooks.html

as well as this neat little utility, CoconutBattery:

That said, it seems like a lot of people were not happy with their battery's charge capacity. It's maybe a good idea to check it just before your first year warranty runs out (no replacement after a year, even with extended care, according to the guy at the store a few weeks ago).

Thanks for all those valuable information, my macbook is very new i bought it just three days ago, and this is what i noticed

1) first day i charged it to 100%.
2) second day i used to laptop without connecting it to the charger and the battery lived for only two hours approximately.
3) third day I used it and it also lived for only two hours, then i charged it again, but this time when i unplugged it the battery lasted for around 4 hours so i think that this anomaly happend to me only because the battery was still new ;)

anyway macs are really great, finally i got rid of this damn windows ;)

thanks all.

Many reasons

1) I find I like doing my Java development in Linux, like having Apache, Tomcat, and App Server, and running maven and svn and IntelliJ
2) Testing that stuff in a "production" like environment.
3) Another environment to test my app from. I can run my app in Windows, Mac, and Linux and make sure that it runs the same on all three.
4) I teach some classes that require me to be on a Linux machine.
5) Having all these OSs keep me learning things that I need for jobs and to train.
6) Some applications that aren't available on other OSs
7) Impress the chicks.
