That's the sort of argument I label "all sign, no magnitude".
How much faster? If it took one minute of battery life off a 10 year
battery would that be a problem? 30 minutes?
How does that compare to other factors like ambient temperature which
also affects battery life but we mostly consider "in the noise"?
Could we make the battery just a little more powerful? How much power
would a bit of circuitry waiting for a "turn on! there's a new message
coming in!" need?
etc.
