I am wondering what people with the new Unibody MacBooks (that carry the built in 7hr battery) are getting in real life usage? I just got the mid-range 15in UMBP and am for the most part very happy with it. The only thing is the battery, which is advertised as lasting up to 7hrs, isnt very strong. I mean I never expected 7hrs to begin with so I am not surprised that I dont get that. But I would have thought that at least I may get somewhere around 5hrs of light use and 4hrs with more heavy use. Something like that would have satisfied me. Instead though I find that I get 3.5 to 4 hrs with fairly light use (textedit, a quicktime file/audio only, safari/moderate web browsing, VLC/occasional use). I mean my previous (black plastic) Macbook gave me around 4 hrs with even heavier use (add Final Cut to the list above). So I am a bit disappointed. And once I install Final Cut on here who knows how long it will last? 2hrs? 2.5hrs? pfffft, to that. If they are advertising 7hrs and the previous non-7hr batteries perform just as good, if not better, then I have a problem with that. Anyway, despite all my crying and complaining, could some sympathetic people who have some real life results with the new "7hr" batteries post them here for comparison. You can also let me know how easy you think this will be to get covered by warranty, and if anyone has already replaced one under warranty because of poor performance. Also if you think I am just over reacting and that I should just expect less hours and be satisfied with 3.5hrs on a brand new computer that is supposed to offer 7, I am also willing to hear that.
