I have a 2016 legacy 2.5 limited. As of 2021 I've replaced 3 batteries and about to put my 4th in. I did a drain check and on Fuse 9 under hood/main fuse box I get 0.6 amp drain then when I pull the fuse it drops to 0.06 amps. This feeds the Data Communication Module / DCM. How long should it take for the DCM to go into sleep mode? Has anyone changed out a DCM, how tough is it? Per the manual it looks like you have to pair the DCM to the car, can that be done by a DIY person? I don't use starlink or SOS or Info button on Telemetric do I absolutely need to pair the DCM? What have others identified with dead batteries.

What did you find what your issue was? I have a similar draw of ~0.6 amps. When I pull DCM (data communications module) fuse the amps drop within spec ~0.05 amps
