Improve iphone 5 battery life?

I've had my iphone for nearly a week now from brand new and the battery is just literally draining all the time. I've looked on the Internet and done most of the tips like turn off location services, Wi-Fi, iCloud, Siri, turned brightness down etc. But it still hasn't made a whole lot of difference. Does anyone else have another solution to the problem? I was thinking of just resetting the whole phone and seeing what happens. Or maybe I'm just being impatient and need to let the battery kick in more. Anyhow any advice would be real helpful, thanks

Double click your home button and hold the apps and click the - sign until they disappear this is gonna exit your apps from running and taking up battery power. Turn your Wi-Fi off when charging. Charge when your battery is super low not half way. I also heard turn off the phone when it's charging will make the battery last longer. Hope this helps some!

Turn of "Push"

That should save a lot of battery as Push constantly checks for updates on all of your apps.

Hope this helps
