Power Consumption and at+w32k

I’m attempting to get at Q2686 into slow idle mode with at+w32k=1.
I pull DTR high, issue at+w32k=1 and then pull DTR low.
Power comsumption sits at about 12mA and when DTR pulled low actually increases to 20mA+.
Do I need to turn off the UARTS to achieve the power savings?
