How to fix my broken batter for my Iphone?

My phones battery is really messed up. It's only lasting a good 1 hour of usage and when I charge it, it charges right up to 100 within an hour, and once again, within an hour it will die on me. I have an Iphone5c and this has never happened to me before. It just started happening this past weekend and I don't know how to fix it.

You can change the battery of your phone

The ONLY way to fix this is to replace the battery, you can either do it yourself (if you know enough about electronics) or you can get Apple to do it

  • Which latest iphone is batter? I want to buy a latest iphone with advanced technologies, there are so many iphones in the market so i'm very confused that which one is better for me. I want to invest near about $500. Please suggest me.
  • Where can I fix my broken iPhone? So my ex had my iPhone and was mad and broke it completely. The screen is cracked really bad and pulled back from the cover is it possible to get it repaired instead of buying a brand new one?
  • When apple replaces a broken iphone, do you get to keep the old broken one? The back camera on my iPhone 4s broke (just stopped working), so I called Apple and I have an appointment set up to replace the old phone with a brand new one. But, I want to know if when they give me the new phone, will they let me keep the old one? The phone still works fine except for the camera. In fact, it's almost perfect. And obviously I want to sell the old one on ebay to make a boat load.
  • My iphone's aux in is broken how can i fix it? No matter what headphones i use on my phone, the sound is all messed up. I went to the apple store and they said nothing can fix it, but when i plug my phone into a speaker made for iphones via the ipod connector, i get normal sound. Is there any cable thats aux in to the "apple connector" so i can use my headphones?
