iOS Question App Disclamier

Hi Everyone,
I've try to put on the iTunes store a my app but was rejected because I use location background mode.
Apple replayed saying:

Your app uses the Location Background mode but does not include the required "battery use" disclaimer in your app description.

Next Steps

Please add the following disclaimer to your Application Description:

"Continued use of GPS running in the background can dramatically decrease battery life."

Where do I've to insert this disclamier? In iTunes in which field ? In some kind of metadata inside the App? And when I'll resubmit the app to iTunes Connect do I have to change the version number?

Thanks for any help.
