Your battary required to be replaced and it will start working Fine.
It hasn't died with a high % showing in quite a while and when they tested it at the Apple Store, it was still "good". They also told me that apps use more power when they start up, so I should leave them open. I talked to someone who repairs phones and she said it should be charged before it drops to 20% to get the best battery life.
