After virtually everyday use since late February in and out of the charger every day, if not more. I have had constantly longer than 5 hours of battery life.
However, today, It has only lasted me around 3 hours, a sudden change from the day before. I know battery life is reduced over time, however, is it usually this quick.
Thanks,
harry

You can download Coconut Battery to see if the health of the battery has decreased, though it usually decreases slowly. I've had my Alu Macbook since they came out, and i am at 101 cycles now, health ranges between 96% and 100%

If you were doing something processor intensive the battery runtime would drop which is normal. For example watching video runs the battery down more quickly. Also if you were doing constant downloading of a large file via wifi the runtime would be decreased as the wifi would be constantly transmitting rather then intermittently as when you are reading webpages.
