The Barcode Edition is designed to always stay on the camera. This is why we integrated smart power saving functions. While active and taking pictures the Barcode Edition Bluetooth Module D200+ draws 11.0 mA from the camera. After 15 minutes of inactivity the Bluetooth® connection is disabled. It then only consumes 1.85 mA. After 45 minutes of inactivity the Barcode Edition goes into a deep sleep and only needs 0.066mA. This is so little energy, it would take several years to deplete the camera battery.
