My iPhone (fully charged), when I've closed it (using the top button), cycles on and off every 60 to 90 seconds. The home screen lights up for about 10 seconds, then goes black again. That is also about the same disconnect/reconnect timing that happens with my Bluetooth Streamer Pro 1.3 media link when I am talking on the phone. It cycles back and forth from my ear buds to the cell phone. In my Settings, already have checked the Bluetooth settings, checked Forget the Streamer Pro 1.3 and paired it again, tried turning off all the cellular connections for apps, and reset the phone (turning it completely off and on again). None of that has stopped it. Any more ideas for me?
