Connection problems with MetaWear RG - doesn't connect unless charging

I'm using MetaWear RG, the MetaWear app, and iOS 7.1. I'm unable to stay connected to the device unless it is plugged into a charging source. It would seem like a battery issue but it reads '99'. I've updated the firmware and downloaded the latest app version, closed/reopened the app, and turned the phone off/on. Even when plugged in, many of the app's functions don't work, such as the LEDs, although the accelerometer does work.

I'm at a loss has always worked in the past. Any suggestions are welcome.

Thank you in advance.
