Anything is possible...I've had a bad battery in the past. Do you have insurance on it? If so, you can take it to a sprint store and they'll swap out the battery for you. Another completely random thought...is your storage card working ok? I had an issue in the past where I was having horrible battery drain all of a sudden. I had the phone replaced and the problem still occurred. I noticed that my sd card wasn't showing up in file explorer. The card had been corrupted somehow and the phone was constantly trying to read it, causing excessive battery usage. Took the card out and issue was resolved. Probably a longshot, but like I said, anything can happen.
