Hi,
if you use a custom circuit, switching the power of the pico completely off might be an option. I'm using this approach in combination with a real time clock: The RTC running from battery triggers an alarm, powers the circuit including the pico on via a mosfet, the pico is doing its thing, and as last action switches itself off using the same mosfet.
When switched off this way, the current drawn is very low (µAs), limited by the mosfet and pull up resistors.
You can find more details here: https://github.com/c0de111/esign/tree/m ... re/circuit
