10 - 30 minutes
The battery did not hold a charge, and speaker output no sound whatsoever.
Initially, I ordered only the battery, and confirmed that would fix that issue first off. Once I confirmed that it did so, I then ordered the speaker. At the time of ordering the speaker, I also ordered a dock connector, just in case I needed to replace that as well. Replacing the speaker though solved the issue. :)
Just take your time and things will go smoothly.
