How long does your iPhone battery last?

Do any of you getting 10, 11, to 15 hrs. usage game much? I play a couple of games throughout the day and have not seen those numbers on my 5. I've been getting 5-7 hrs usage and 14 hrs. standby for a typical day.

playing CSR Racing through out the day, whenever the gas fills up, I play until empty and wait for the next fill up. That's like every hour and playing up to 15-20 minutes straight with low sound at 3-5.

Thank you to those that suggested turning off the battery percentage! What a difference it makes not looking at the numbers drop every few minutes. Since changing it, I haven't plugged my phone in to charge and I have been more at peace. Again thank you!
