Make sure the lightning/30-pin of the lower portion of the case is clean and dust free. Give it a spray with pressurized air if you can. If not, try a hard reset of the device and it should be working again. The only time I had an issue with my Mophie on 7 was because of a few dust particles in the 30-pin head of the case
