Science Buddies: "Ask an Expert"

I'm doing a project testing apple's iPhone 3GS and comparing it to the amount of time Apple says it will last on their website. I have already completed the project and it was between this and another project that would cost me money I don't have. Long story short my question are...
Does temperature affect lithium battery life?
Does the battery life decrease as it gets hotter?
How does multiple items (motion sensor, light sensor, etc.) affect battery life?
Does CPU and RAM use affect battery life?
