I want to run NanoPi Neo Air with lowest power consumption from a 5V power bank?
What power modes are available on NanoPi Neo Air with Ubuntu LTS and are there any details on power consumption available?

-I assume wireless Wifi/BT can be powered down?
-run just CPU Core0 with lowest frequency and CORE 1,2,3 turned off. How to set it up?
-slow down RAM frequency? How to set it up?
-can peripherals not used be disconnected from power supply rail?
-can H3 CPU be turn on from sleep via GPIO IRQ PIN or RTC IRQ?
