Hello,

We do not have any product which use battery going to 2V, so, I can not recommend.

Current consumption can vary on several factors like battery voltage, rate of uplink data transmission, antenna design, network etc.

There you can find modem current consumption https://docs.nordicsemi.com/bundle/ps_nrf9160/page/_tmp/alta.nRF9160/autodita/APPLICATION.CURRENT/parameters.id_current_modem.html and GPS current consumption https://docs.nordicsemi.com/bundle/ps_nrf9160/page/_tmp/alta.nRF9160/autodita/APPLICATION.CURRENT/parameters.id_current_gps.html in our datasheet.

Thanks.

Hi,

Thanks for the reply. Do you have any recommendations for the boost convert ? And another question, what could be/is the max current the nrf9160 can consume when connecting to the network and sending message to a server for example ?

Sorry for the specific question! Thanks again!

Hello,

The nRF9160 has an operating voltage range of 3.0V to 5.5V, with 3GPP compliance requiring a minimum of 3.1V

Yes, you can add a boost converter to make stable voltage supply for the nRF9160 when using a battery that can drop to 2.0V.

Thanks.
