I haven't had any cutting out issues with mine yet, but one of my concerns has always been the non-detachable lightning cable. From my experience with TONS of varying quality lightning/micro USB/mini USB/proprietary cables, they will always be the weak link. I know even with detachable cables there can be issues with the port, but that seems to occur far less than problems with cables. I really wish they had gone with a detachable cable, which also would have allowed for switching between lightning and USB.
