Iphone 5 wont charge

If it is in warranty, return it. If you got it from a phone company, take it back there and let them look at it. I don't think it is fixable.

Try to factory reset the device using iTunes

Is it a matched brand charger? If it isn't, then its more likely went out. Most phones use a special connection inside the charger to tell the phone to accept charge.

Before you can charge your iPhone on the computer, your computer needs to install the drivers for it. You might have to reinstall the drivers for it. A good way to check if the drivers are incorrectly installed is to see if iTunes detects it. Try updating your iTunes since the old version of iTunes won't work with ios6 and all iPhone 5 are shipped with ios6

I think it may be broken.You need buy a new iPhone battery charger.

Does the computer still see it when plugged in? Does the phone show that it's charging?
If your answer is no to the above questions, then you need to do a DFU Restore.
Here are the steps:
1. Turn off the phone. 2. Hold down the power (the one at the top) and the home buttons. 3. When you see the Apple logo, release the power, but keep holding the home button. 4. After you do that, open iTunes and it should tell you that your iPhone is in restore mode. 5. Restore the phone.
Hope this helps.
