Reply To: Monitoring power consumption

@shicks surely the issue isn’t how long it lasts – it will always run  out of power at some point, or even worse batteries loose capacity, what was working decays – the issue is how to reliably recover when it has run out of available mA.  ?

The reliable bit – as in all engineering – is to add a buffer for real world component variations and that it just works for the “large power demand”  when the modem turns on – across the expected usage of the battery.      When Li-Ion batteries run down, their impedance goes up, they can supply less current at that voltage, and they need special charge management while they acquire a minimum charge .
