Why does my Macbook pro 15" lose charge so fast? The computer is only a year old and lasts under an hour unplugged from full battery. It also gets VERY hot whenever I use it without the cord.
Sound slike a dead fan or sensor.
Run a #3 Hardware Test write down the error codes, backup your files off the machine, delete what you don't want seen and take it in for service.

How do I securely delete data from the machine?
Thank you! I already made an appointment at the genius bar. How do I run a #3 hardware test?
You should also check Activity Monitor to see is a process is using up much more %CPU than it should. That would help explain both the heat and battery issue.
I can see how a dead fan might cause the heat issue, but I don't see how it would drain the battery faster.
My 13" does too... But the bat lasts 3 days in sleep.
Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity
