Higher current consumption seen for QCA4020 with and without deep sleep mode

Observing very high current with QCA4020 at J22 pin.

Tested on QCA4020 using QCLI demo 

{lp->deepsleep 0 } gives current of 69mA

{lp-> deepsleep 1 }n gives current of 73mA

There's only difference of 3mA for active mode vs deepsleep mode. Is there an explanation for this from software perspective or any possible leakage from malfunctioning external capacitor. Please help me understand the issue and provide any inputs on datasheet measured values for deepsleep and active modes

Is the power measurement part of IMPS or active activity ?
Kindly refer to Document: 80-YA121-147 QCA402x (CDB2x) Power Measurement Test Guide  for information on commands to verify system power and use case.
Refer to latet QCA402x SDK release notes for appropriate power dashboard use case values.
