How's the battery life on your iPhone 5?

Hello iPhone 5 users, I'm debating whether or not to buy an iPhone 5. I have the iPhone 4 and I get about 4-6 hours of usage on a regular day. I've read on other forum posts that the iPhone 5's battery is not as good as the iPhone 4's battery and that there are people who say that they don't even make through the day (I don't know if this because of extensive usage, defective battery or is just because that's the average time people should be getting.

So would you please tell how the battery life has been for you? Thanks.

P.S. Sorry if there are any mistakes in my writing, grammar, or paragraph structure...
