Asset Tracker V2 consumption and ways to reduce?

Hi,

I am trying Asset Tracker V2 application in my custom board and rechecking results with DK to ensure no hardware reasons are there. Using SIM supplied with DK and using PPK 2 to see consumption.

So, overall it's working, though between location search cycles, when I assume it has to go to PSM mode, it stays at 650-750 uA range, which is understandable for DRX and I was expecting PSM and going down to 200-300 uA range which doesn't happen. 

CONFIG_LTE_PSM_REQ=y
CONFIG_LTE_PSM_REQ_RPTAU="11000001"
### 20 seconds active time.
CONFIG_LTE_PSM_REQ_RAT="00001010"  
These are set by default and I see in CEREG report these values to be accepted.
 What I could be missing here ?
Regards
Grigor
