How long is the battery life for an Iphone 5?

I know if differs depending on how much you use it/what you use it for but what is, generally, the amount of hours you can use your Iphone5 for? How can I extend this time to last me longer?

Ok, I get about 5 good hours from my iPhone 5, if you want the battery to drain down slower, turn off notifications and turn brightness down to the lowest you possibly can!

If you type in www.apple.com in your URL space and then click iPhone 5 once on the Apple page, it will give you a brief description of the battery life and overall phone performance
