Hey all- long time reader- first time poster. I've recently purchased a new Macbook 2.2 and didnt bother upgrading the ram from apple ( Are you surprised?). For the first week of ownership i was averaging about 4 hours or more of battery life while running the basics. After the first week my new ram showed up that i purchased off the internet. I took advantage of a great deal and put in the max amount of 4 gigs. Every since then ive noticed a little less battery life while running the same programs (Closer to 3 hours). Could this be a result of the higher RAM? I've looked around on here and could find anything posted about this already. Thanks for your help!
