Question about nRF9160 power consumption.

[xinjiang]

I got an average DRx power consumption of 415.03 µA for 2.56s in the Online Power Profiler for LTE. But unable to get the average power consumption of eDRx.

In the following eDRx case, the average power consumption is (415.03 * 20.48 + 23.82 * 61.44) / 81.92 = 121.62 µA

LTE CATM1 Standby 81.92s eDRx PTW 20.48 and DRx 2.56 Sec

Is my calculation method right?

Hi,

with interval less den 5 sec, the DRx is the average current. 

With interval more then 5 sec, iDRx = eDRx.

So 415.03 uA is the  average power consumption, no additional calculation needed. 

Best regards,

I don't understand what you said :

With interval more then 5 sec, iDRx = eDRx. 

When 81.92s eDRx PTW is 20.48, isn’t there a 61.44s without DRx waveform?

Is the average power consumption in 61.44 seconds also 415.03 uA?

I made a sample picture like this:

Hi,

please have a second look at the power profiler and the user guide:
