Reducing power requirement

I am trying to design a product using the MangOH Yellow to work on minimal power.
I have managed to get it to run at 7 to 30mA (@5v) with the radio active and connected. It has bursts of higher current when it is transferring data. This was achieved by pulling GPIO41 low.
With the radio off (cm radio off) and mainly in sleep mode, it still draws 7mA.
Is there any way to reduce the current further (without taking a soldering iron to the board)?
ULPM seems to require a reset and hence is not useful in our application.

does this help?
