I have a Macbook I bought last July, and the battery life has declined significantly in the less than a year I have owned it. I went from over four hours of battery life to roughly 1.5 hours. I take good care of my computer (don't leave it on for days, let the batter die 100% before charging if I can help it). I don't think I've made any changes in the way I use it either (screen is same brightness, mainly used for web/email, nothing processor intensive). I was wondering if Apple would be likely to replace the battery. I know there have been battery issues in the past, but I was reading on the support site, and it says this regarding the battery update 1.2: "This battery update should be run on all MacBook and MacBook Pro computers and extra batteries that were purchased between February 2006 and April 2007. " Does this mean that only Macbooks purchased between those times are likely to be eligible for a battery exchange? I'd hate to make the 3 hour round trip to my Apple store just to be turned away. Also, how would they test the battery life in-store? I'm worried they have some funny machine that will say my battery is fine, even though in real-world conditions it isn't. Thanks in advance!
