How long does your iphone 5 battery last?

I got my iphone 5 like a month or so ago and my battery lasts only about 5 hours almost to the minute. Its really bad. I don't do anything crazy, or use it too frequently (just regularly throughout the day to text an d check email or facebook or whatever) so i'm just wondering how long yours lasts to see if this is normal or if i got a crappy phone:/

That is not normal, so you should change it.

I would recommend calling or visiting Apple. You iPhone should last about 5 hours with the screen turned on at 50%.
