LTC4162 battery temperature while no vin

Hi

As far temperature concern. We check die temperature keep on updating while system working on battery.
But Battery temperature value remain fix to last reading when working on Vin.
So I doubted battery temperature is not working while operating on battery.
In above all test set force_telemetry_on=1
Please confirm battery temperature updating while operating on battery ?

    Hello,

    Yes, the NTC reading still works when powered by the battery. If you did not change the telemetry_speed register, make sure you are allowing enough time for it to update. It reads at a reduced rate when powered by the battery unless you change telemetry_speed.

    Regards,
