In the iOS app and in the booklet, the setting is called extendedData. In the Android app the setting is called pubExtendedData.

Thanks for finding that, @ckrey!! I was wondering why that person had a problem with Quicksetup-configured Android device and wasn't seeing battery level. (I'd not specifically tested that.)

I need to work out how to support both for backwards compatibility.
