i'm really enjoying my N900
with the long battery tweak

ysss, your a smart troll. Consider:

Code:
power=a*capacitance*frequency*voltage^2
As power is a function of the square of the voltage, power usage is has an exponential relationship with the voltage used.

Consider this graph:



It can be read from this graph that the best voltage/frequency trade off is 600MHz as:

The V differance between 250-600 is the same as 600-700. The 600-700 voltage increase is the first significant increase therefore if one was attempting to use the greatest frequency with the least increase in power usage they would limit the maximum speed to 600MHz.

Further to this you may notice that there is little difference between 250-500 compared to 500-600. This would suggest that you would want the CPU to be operating in the 250-500MHz region, 'dipping' into the 600 when it needed to.

To achieve this one would remove ALL available frequencies except 0, 250, 500 and 600MHz then set the up threshold to something reasonably high.

This combined with smart reflex is how this extra battery life is achieved. The reason it is so revolutionary is because of the 'technical level' of the participants of the thread who have not arrived at this undervolt/extend battery life conclusion.

There is no logic here as logic implies there was a rational process of factual reduction that lead to this conclusion.
