I captured 10 seconds of measured idle current in both configurations, static ip (blue) and getaddrinfo (orange):

The large current spikes are definitely periodic about every (1.25 sec) and account for the increase power consumption. I also ran Segger Ozone with J-Trace to see if there are any instructions running on the application processor. The only instruction load was from the Zephyr kernel idle thread that executed periodically about every 20 seconds with only a few instructions. This seems to indicate that this issue completely resides within the modem firmware.

Would it be helpful to run a modem trace?
