Average iPhone 5 battery life?

So me and my friend both bought an iPhone 5 about 3 weeks ago, and his battery is better than mine… I have to charge it about 3 times a day(not even joking)… But he only chrages it 1 time a day. And my battery drains quickly and it gets really hot when it's charging. So I went to apple and complained and told them that I had a defective unit, a they tested my battery and told me that there's nothing wrong with it, they also told me that my avg standby time is 17 hours and refuses to fix it or exchanged one for me.So… What's the average standby time for iPhone 5 and what should I do?

And thanks.
