So i've been debating with myself as to how I am expecting the battery life to perform vs. how it should be performing. in November I picked up the Unibody MBP 2.53HGz. I'd say this machine gets low to moderate use. When i do use it for extended periods of time i've got it plugged in. I exclusively use this machine on better performance and have felt that since day one the battery life doesn't seem all there. On average i lose 1% battery life per 1 minute of use. When i am using it via the battery i generally don't use it long enough to drain the battery, but the charge is always significantly diminished. I've been avoiding bringing to the apple store, but now i am have additional issues with the machine so i think its time to have it looked at. How is apple with regards to replacing the battery? Do they take my word on it? do they hold my machine for days and run tests on the battery? my other issues that have arisen are when connecting an external monitor i get millions of red dots popping up all over the screen. you have to do a considerable amount of jiggling to make them go away. also noticed when i use it for recreation World of Warcraft. it used to run at 40-60 fsp and now seems to be averaging 12-20 fps. The longer the machine is running the choppier the frame rate gets.
