Q: iPhone 4 update to iOS6: Error 21

I have just attempted to update to iOS 6 on my iPhone 4 and get an error 21. After reading all the various forums some suggest it is a battery problem and the battery should be replaced. Is this correct and have others encountered this issue? Does anyone have any other ideas how to resolve this issue?

iPhone 4, iOS 6, Error 21
