Well that really depends on your use case Cord. I am saying if a person wanted MAXIMUM battery they would use the frequency that used the least voltage (obviously if you take that maxim to its logical conclusion the voltage be zero and the device would be off!). I was merely pointing out that there is quite a significant step between 250->600 and 600->750. The amount of extra power required to run the CPU from 600->750 is that voltage differance squared (times by itself) so big steps = even bigger increase in power requirements. From the graph you can see that the voltage step between 250->600 is not so big therefore it doesn't require that much more power.

The point is it is a trade off between power and frequency here and the most bang for your buck is at 600MHz.

The reason for removing unneeded frequencies is because it takes CPU time to check if a change is needed, then even more time to enact this change. From the graph we can see there is not really too much difference in voltage between 250->600 so why not just spank it all the way strait to 600?

I run my device at 805MHz as I am prepared to take a mild hit in battery life for the sake of performance.

Morphine ay? You either like to get REALLY high or...well you fight it.

where is karam? what do u want to say abt his battery tweak?...so finally what shud be the whole settings.if i want to save battery.like the whole thing cz i frgt what i hav changed and what not.

i think we should wait a bit more
until karam uploads the modified ideal profile
then we decide what way to do

PS : what i have figured out from vi_ suggestion is
he only increased the thresold value
and removed the powersave_bias
and why is it pointless
i use N900 from the day released and i can tell that powersave_bias
gave me at least 10 hours

cheers for that vi_ i've got it i'm clearer on that now
yeah morphine had an op last year and recovery didn't go exactly to plan, rehab awaits me when i finally am fixed

what are the settings? tell me the settings...ideal or default jst copy it and paste it here plzzz

i will wait..so can u jst copy it herethat what were the default and ideal settings before editing it.i dint copy it.my phone was better before.plzzz paste it here for both

refer back to first post and change your settings in default and ideal back to original values.
-----------------------------------
SMARTREFLEX_VDD1=1
SMARTREFLEX_VDD2=1
-----------------------------------

To

-----------------------------------
SMARTREFLEX_VDD1=0
SMARTREFLEX_VDD2=0
-----------------------------------

And change

-----------------------------------
POWERSAVE_BIAS=20
-----------------------------------

To

-----------------------------------
POWERSAVE_BIAS=0
-----------------------------------

where is karam?its his tweak..y isnt he replying

probably busy, he too has got a life away from here

yes dat i know..its given in the first page..i meant what frequencies...max min..can u suggest one to increase battery life..and the default upthreshhold.karam pm d me..he said dat he will c.and some one also pmed me saying that karam's patch is fake:S
