Macbook Issues

I have had my Macbook for a little over a year now and I havent really been happy with it. Lately when I charge it full at 100% and I turn it on it says I have 2 hours of battery left which is without opening any applications and having it on the lowest screen brightness. Also, it fans like CRAZY and becomes really hot even when I do something simple as open a youtube video or just if I have a couple applications open. I paid over 1400 bucks for tihs thing and it's ridiculous that it wont even perform well. Im going to go to an apple store but since its been more then a year i will probably have to shell out a lot of monye to replace the battery

Has anybody else had these issues or had any unhappiness with their macbook? The battery seems horrible and the fanning is uncontrollable. What are your thoughts?
