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. Low Power Mode allows the device to collect data for longer before the battery completely depletes.

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:

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:

    Controlant Saga Logger displaying Low Power Mode. Text on the image: "Low power mode. The logger is now in low power mode. Please charge 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.
