Call your phones network company (at&t, verizon, ect.) Tell them your problem, and they will put you on the phone with technical support. Tell the person from technical support your problem and they will give you instructions. All you have to do after that is follow their orders. I had the same problem with my phone. (:

Firstly we need to narrow down the problem - Is it the charger, battery or handset?

If you can try with a different charger so if you are trying with AC charger, try with a USB charger.

If you can swap batteries, to test if another battery in your device will take a charge.

Lastly, try your battery in another device if you can to see if that device will take charge with your battery.

If you can't test on another device, I would try another battery - its probably the cheapest option. A quick glimpse at the battery in your device may give you an indication - does it look warped?
