The standby time is estimated under the condition of operating with LTE CAT M1 and the CSQ is greater than 15, working at a constant ambient temperature of 25°C, where GNSS signal is strong enough and under open sky. 2. The battery life estimation is based on LTE CAT M1 Connectivity and may be influenced by several factors such as network coverage, ambient temperature, sensors’ setting, peripherals, installation location and orientation, etc. If you’re interested in power consumption calculation of our device, please contact with our sales or FAE to get
