I keep hearing this rumour, but it's confusing on two counts:

1) The single biggest drain on the battery is the radio transmitter, 
not the CPU, which is generally reasonably efficient.
2) If crypto really was such a major drain on the battery, then given 
that battery life is so crucial to the market, why on earth haven't 
they got crypto processors (which have a markedly lower power usage 
for crypto work than a generic CPU).
