I just ran coconut battery on my MacBook and ouch! Yeah, I think it is time for a new one or at least start to think about one. I am only getting about 2 hours of battery life now compared to 4+ that I was getting. I am not too sure if it is correlated to my processor going crazy when I am on my battery but I am sure it is not helping. I am going to have to research it. The image on the right is my Black MacBook and the one on the left is my 17″ MacBook Pro. I have now idea now what is gone on.
