a more powerful processor doesnt always need more power ...speed is not the only thing that improves efficincy as well ...if that was the case we would have our phones connected to car batteries by now ..the one thing that improves at a snails pace is battery capacity

its because the OS is written around the processor and not the other way around, so much is optimized and its amazing to see how much difference optimization and adaption makes a difference, if you want to look for yourself get an n900 and load meego 1.0 onto it, and then load nemo mobile onto it and look at how much performance has been gained through optimization and adaptation.

i think its why android even with dual core processors still manages to find places to lag, like a cluttered home screen, ive heard here and there the OS isn't that good at allocating its resources.

I think it does, cos the frequency of the oscillator is higher...
(http://en.wikipedia.org/wiki/Clock_rate)
Which is why, slower processors also dissipate less heat... while more powerful processors require more cooling.
But yes... (wishfully thinking) we would do well to have the iron man thingi on out phones
The Cortex-A9 power-optimized hard macro implementation delivers its peak performance of 4000 DMIPS while consuming less than 250mW per CPU when selected from typical silicon.
The Cortex-A8 processor can meet the requirements for power-optimized mobile devices needing operation in less than 300mW; and performance-optimized consumer applications requiring 2000 DMIPS.

What you have heard is FUD. I first started seeing this repeated as an excuse by WP7 users as a reason why they don't need faster processors or dual cores. They often shout about how these things are useless. It's sour grapes/cognitive dissonance. It's FUD, one person hears it then repeats it. Little do these WP7 users know that their OS is lmited to a WVGA resolution for a reason, by policy, and that soon they will get their dual core faster processors, at which point I'm sure they will all change their tune. Android is just the OS where the phone is not limited, where the newer technology exists, the higher resolutions exist, Flash exists, it is just currently the OS doing more and therefore needing more.
If you want actual information about how Android allocates resources look here:
https://plus.google.com/105051985738...ts/2FXDCz8x93s
As for newer faster processors being less efficient because of clock speed, again, not as easy as that since they do not operate at a single constant clock speed for all tasks and if that wasn't complicated enough you also have to consider time. For example, is a process that takes 5 seconds to complete at a lower clock before going idle more efficient than spending 2 seconds at a higher clock before going idle. I recently read a paper which said performing quick bursts and becoming idle quicker is actually more efficient but I can't find a link.
Merry Christmas everyone.
