Some tips:

- Simplify your application to ensure you get low idle current and then add functionality and ensure you still have low idle current.

- Devicetree try to add zephyr,pm-device-runtime-auto; to the various peripheral nodes.

- Kconfig try to add CONFIG_PM_DEVICE=y, CONFIG_PM_DEVICE_RUNTIME=y

and double check here for tips:

Hello,

Most examples should already be powered optimized if you add CONFIG_SERIAL=n. But you can find this useful:
