Does your iPhone 5 lose battery quickly?

My iPhone 5 loses its entire battery charge in one day! Does anyone else have this problem? How do I fix it? I tried "deleting" the apps when you double click the home button and it doesn't really help with the battery. My brightness is also pretty low. Help?

Some report that the new ios 6 software drains the battery. Sometimes it also depends what apps you use. For example, the Tumblr app drains my battery on my iPod Touch 4th generation within 15 minutes. However for my iPhone, i haven't been experiencing any battery excessive drainage.
