My iPhone 5 battery runs out really quickly?

I just got my iPhone for Christmas and the battery is terrible. It is fast and does everything fine but the battery lasts like 2 hours. I have turned my brightness down and Bluetooth off etc and the battery is still bad. It drained 30% today in about 20 mins and it also takes about 30 mins to charge. Is there anything I can do or is there a problem with my phone.

Before you go to sleep, put it on charge and leave until morning.

It's apple what do you expect? Best think to do is get a new phone not an apple one though the are rubbish but if you still want to have one buy a new battery if you can get yours out as you may over charged it x

Hmm… Do you frequently close apps out? If you don't that could be a drain on your battery. If you don't know how, just double tap the home button, and the screen will slide up to reveal all the apps still open, then just hold down and erase them, it won't delete the app for real, it'll just close it out.

also, if you have a bad connection or do a lot of roaming, or if your phone is always trying to find and connect to Wi-Fi, that could be a drain on your battery life also.

If the problems persist, take it to the phone store you got it from, and ask for help from there, they should be able to help or guide you in the right direction.

I'm having the same issue with my iPhone 5. I got it as a Christmas present but a month early and mine is shocking too. Though iOS 6.2 was released a few weeks ago and it's in the news that is effecting a lot of the iPhone 5 users.

But try some of these:
*Double tap the home button when unlocked, hold onto your apps until they jiggle and then tap the red circle to close them down properly (If you haven't already)
*Turn off LTE
*Turn off push notifications for apps there's no need for
*Turn off certain iCloud settings
*Run your battery down to 0% and then charge it up to 100% undisturbed
*Totally reset your device and start again
*Reset your network settings

For some people, they work, for others they don't. I always run down to 0% anyway, I only sorted out app notifications today so it might fix, but the rest of them I've tried and it has made no difference. If not, I would wait and see what updates Apple release within the next coming weeks/months and see if they fix battery issues, if not, then I might take a visit to an Apple store, even though my nearest ones are 39 miles away and the other is 43 miles away, so I really don't want to.
Also, I've asked these three questions below in three different categories just earlier, so if you want to keep watching those to check and see if I get different answers to you and I'll add this one to my watch list too for the same reason, let's hope we get the answers and help we need!

If you leave it in you jeans trousers poket, will absorb heat your body heat, that's effect your battery

My science teacher said that you can't always have your phone charged there will be no space for it to build up memory.

My iphone 5 is fairly new and runs out so quickly. I barely use it. I will try the app thing, although I don't use apps hardly. I'm very disappointed in it. My GS3 ran for ages before the battery went down. Much better phone.
