Why does the unit drain batteries when it’s switched off?
Quick answer
Ensure the device is fully turned off and updated. Batteries naturally lose charge if unused for extended periods.
If your unit appears to drain the battery when off, check the following:
- Ensure the device is fully switched off by holding the ON/OFF button for more than 3 seconds until a countdown appears. Pressing the button for less than 3 seconds activates “Display Off” mode, which still consumes power.
- Confirm your device has the latest firmware installed for optimal energy efficiency.
- If storing the device for a long period, note that batteries naturally lose charge over time. Follow the user manual to maintain battery health.
