I had the MacBook Pro 13' since it came out and the battery life was amazing back then. Now after 10 months of use and 290 cycles the battery decreased to 92% capacity. Now it holds about 4 hours with light browsing and not more than 3 with heavy browsing and youtube 720p videos. I also swapped the hdd for a 5400 rpm 500 gb scorpio blue. The laptop gets very hot now and the fans are constantly spinning. It has that ocean breeze sound. Is this supposed to be normal on a laptop that has a 7 hr battery life and a 1000 cycle life. How much are you guys getting out of your macbook pro 13"? Is there something i can do to improve ht battery life?
