** Battery consumption is indicative. Battery lifetime is affected by many factors including:
● temperature, in which the device operates
● signal conditions
● type of sensors installed in the device
● number of BLE connections (i.e. to download the data from devcie's memory)
● number of user / threshold triggered transmissions
● number of new configurations sent from the server to the logger
● number of network registrations (if device changes its location, resets, there are some network
issues, device needs to register to the network again what consumes a lot of battery)
● number of FOTA updates (not included in the model)
● complex physics of Li-ion batteries (in the model a simplified calculation is used). Due to physical
processes which happen in the battery, maximum battery life time is 11 years. After that time, the
battery will discharge, even if it is not used
