Battery life

[gilljoy]

Well i just got this macbook yesterday and its brand new out of the shop etc.


im not getting anywhere near the advertised up to 10 hours battery life. i was sitting on mac rumors and had 2 other tabs open in safari and was downloading a small file only a few hundred kb and its only saying that i've got 1 and a half hours battery life.

is there any program that i can run to optimise the battery or something?

Have you calibrated your battery yet?

This should answer most, if not all, of your battery questions: Apple Notebook Battery FAQ

Also have a look at Activity Monitor ( Applications / Utilities / ) and select All Processes and sort by CPU to see what the culprit may be.

is that actual usage time or the estimate?
