How does the logger battery saving mode work?

In this section:

When the battery level goes below 10%, the device enters Low power mode.

When the battery level reaches 5% or less, the device enters Hibernation mode.

Low power mode: Battery 10% or less

When the battery level goes below 10%, the device enters low power mode and only wakes up every 24 hours to sync data.

In low power mode , the device:

  • Switches to 24-hour wake-up interval, whether in shipping mode or standby mode.

  • The display indicates Low power mode with a full-screen service message:

    Low power mode. The logger is now in low power mode. Please charge the device.

The device remains in low power mode until one of the following happens:

Hibernation mode: Battery 5% or less

When the battery level reaches 5% or less, the device enters Hibernation mode and suspends everything except measuring temperature every 10 minutes.

In Hibernation mode, the device:

  • Measures temperature and logs in the memory.

  • The display indicates Low power mode with a full-screen service message:

    Low power mode. The logger is now in low power mode. Please charge the device.
  • The following functionalities are stopped in hibernation mode:

    • Modem wake-up

    • LED lights

    • Light sensor

    • Accelerometer

    • Barometer

    • Wake-up and LED behavior due to "button press" is switched off. Button events are still registered to memory.

The device remains in Hibernation mode until one of the following happens:

  • The device battery is fully depleted.

  • The device is charged until the battery level reaches 15% and the device resumes normal operation.

Note

External variables (e.g. low temperature, poor cellular signal, etc.) and the battery’s health can affect how quickly the battery depletes.
