Enabling Standby mode for your Compute Pack or Controller can help preserve your device's battery life while not in use.
Enabling Standby Mode
Compute Pack and Controller Standby are both enabled from the "Battery" menu in the "Settings" menu. You can enable or disable them individually - scroll down to the standby option for component you wish to enable standby for, and toggle it on. Disabling standby is done by toggling the toggle back off.
