I dropped it in water and it wont charge at all

Priyanka Neupane, you did not tell us what you did about the water damage. My first suggestion would be to stop charging it and remove the battery. Do not try to turn it on until it is cleaned. Rice my be great as a first aid and excellent for cooking, but it is not great to repair phones. Disassemble your phone, take a look at this teardown and see if you are up to it. Once it is disassembled, clean every part, connector and cable end with 90%+ isopropyl alcohol. You can use a soft brush to help you with the cleaning, be diligent but careful so you do not damage the components. It is okay to submerge the board. After that, replace the battery reassemble and then re-evaluate. Hopefully a new battery will resolve this, otherwise you are looking at some components on the circuit boards.
