Yes, it extreme power saving for IOT application, let's use Semtech officially calculator to check power saving performance.
We plan to use a 3.6V Li-ion battery, this battery provides 1800mAH power. Then we set SF for 10, BW for 125 and output power for 20dB. Transmit time is every second once.
In below picture that we can see this battery can use for 50,480 days, it equal 138 years! But this is just calculate by only LoRa device, not including sensor, MCU... etc.
