Make sure that you have fully charged your case by following these steps:
1. Take the ThinCharge out from your phone and charge the case by itself using the iPhone charger.
2. Charge the case for at least 6 hours to ensure that the case is 100% charge.
3. Reinstall your phone to the case, making sure that it is tightly connected.
4. Check the charging by holding down the volume up key on the ThinCharge case for 3 seconds. Please note, if the iPhone is fully charged or if the ThinCharge case is out of power, it will stop charging automatically.
