I just started, so my experience is limited to knowing the power draw is too low for USB battery bank to keep it on.
But looking at the device config, I'm wondering if you lower the Nodeinfo broadcast interval, it might wake/check more frequently?

Maybe. I've ordered a nice power meter that can track power consumption over time to give me the ground truth on power usage. Then I can make changes and have confidence in any power differences I see.
