Hi there,
So I feel like some PLUG is needed here, and so much more to be discovered. If seeed would take full advantage more could be gained.
Also Some of the users having issues may not be aware of the Power domains and turning things on when needed, I’m just starting to Scratch the silicon surface 
Thank you for the efforts and enlightenment 
PLUG
The nRF54L Series is among the first publicly available low-power wireless SoCs fabricated using 22 nm process technology. This technology offers high transistor density, lower average power consumption, and improved process efficiency, enabling the creation of compact, efficient, and feature-rich chips for advanced applications.
To optimize energy consumption, the nRF54L Series architecture is divided into four power domains that are independently powered, depending on what features are active at any point in time. This architecture enables ultra-low-power operation by allowing domains to be powered independently, allowing large sections of the chip to be turned off when not actively needed.
