My ProGrip turns off after 15 minutes, is this normal?

Automatic Sleep Mode:
After 15 minutes of inactivity, ProGrip will enter sleep mode to conserve power. This feature ensures that your device can be ready to capture photos or perform other functions when you need it while extending battery life during periods of non-use.

Reactivate ProGrip:
To reactivate ProGrip from sleep mode, simply press the shutter button once. This action will wake up the device, allowing you to continue using it without any interruptions.
