The first thing to consider is optimal configuration of all parameters of an existing software system. The main consumers of power are the Quectel modem, WiFi chip, bluethooth and display.
When these are optimized, a standby time of 24 hours is possible.
In normal operation a cpu-governor already manages the voltage and clock frequency of the CPU's in such a way that upon low demand of CPU activity clocks are appropriately set to a minimum.
There is no use for additional strategies before all the basic problems are solved.
After that, the mentioned package might eventually be considered.
