Battery dying
The battery on my MacBook Pro is dying completely quite fast, even after a full charge. Why is this?

Not being omniscient, two possibilities come to mind. (1) Some software processes are using up your battery. See See how apps affect Mac performance, battery runtime, temperature, and fan activity. (2) Your battery is kaput. Take it in for testing/servicing. See Determine battery cycle count for Mac notebooks.
