BG95-m2 Current consumption when powered down?

I am working on a board and i notice that when the device is cold booted i have a current usage from battery of around 0.6ma witch is what i expect from my external micro, how ever after connect to the network and then powering down via AT+QPOWD=1. The usage seam to be around 3ma is it possible to turn off what ever is still running on the bg95? IN my use case the device will be off for months so this extra 3ma really eats into the battery.

for BG95 power consuption ,pls kindly open the below docs
