Hi All, I bought a MacBook Pro about 2 days ago. It's the 15" model with publicised 8 hour battery life. I was pretty happy when I heard this. I want to know how Apple come to these numbers. So they say 8 hours battery life while playing a video on publicity material, does that mean that you have a video playing and you do nothing else? I was using doing normal internet browsing and replying to some emails the other day, so I use MS Office and Outlook, and I don't think I got just about 4 hours battery life. I can't be sure but I am now beginning to time it under different scenarios to see how long the battery lasts. I have a bad feeling it's going to be well below or even half of what Apple advertise. Does anyone have any knowledge or experience of this? Is anyone else feeling a bit disappointed or ripped off like I am? What is realistic when you are doing normal work like Office Applications and browsing. One other thing, when I went to the Apple store I asked them when the next MacBook product refresh was going to be? They said a refresh happened 2 weeks ago, so the models currently in are about 2 weeks old. Is this correct? Thanks all.
