nRF9160 Low Power Example

Question

Hi, 
 
 I'm currently trying to evaluate the nRF9160 for one of our projects. 
 One key requirement is the power consumption when using eDRX. 
 
 I have tried profiling the at_client sample, but the lowest I've manged with the nRF9160DK is about 900uAs. 
 Additionally, the power profile does not seem to show the expected paging windows when eDRX is configured. 
 
 Is there any low power example, or documentation which can help me with this?

Hi H&aring;kon, 
 I've resolved the issue now. 
 The guide here helped me. https://devzone.nordicsemi.com/nordic/b/blog/posts/measuring-psm-idle-current-on-the-nrf91-dk 
 Edit: The guide seems to have moved. It can now be found here: 
 devzone.nordicsemi.com/.../measuring-psm-idle-current-on-the-nrf91-dk 
 (Note that for the 0.8.2 DK boards, it is SB44 that needs to be cut.) 
 I seems that if you removed the USB, the board will draw an additionally, 70-75uAs from the P24 header.
